Adjusting Aircon at night based on heartrate - any reccomendation/AI to improve based on feedback loop?

Prologue:

I know I get best sleep values from my garmin smartwatch - if I freeze slightly at night but not too much. And next day attentiveness / sports performance pretty much reflect my Garmin watch sleep quality numbers.

I have seen a study by a university where they said IOT based temperature setting in Korea with University students yielded 90° correlation based on heartrate. However they only relied on a questionnair in the morning to assess sleep quality - which is very unreliable to a smartwatch tracking HRV, heartrate, skin temperature, and some algoes for sleep quality based maybe on some more additional sensors.

I know best sleep quality is when the temperature stays rather the same all night and I need darkness - but cannot cope with an eyepad. Freaks me out if I cannot open my eyes properly. That's why an aircon is essential as otherwise even in winter my room instantly overheats once the shutter closes for darkness bevore sunrise even if window stays open. However that limits me to around 15-16° C. minimum temperature

Temperature control is about the most important thing affecting sleep quality at least for me - besides needing

Some factors to consider:

I know I need about 1K colder temperature after moderate sports during the day, and about 2K colder average temp during the night after a hard sports effort. Two to three hard days in a row (a hard day is like 400-500 activity minutes on my watch per day for me) may mean even 3° colder.

I have not yet had a reliable quiet aircon that I could regulate - but in a few days will get a high quality one that can integrate locally into home assistant and should be able to adjust temp accurate to 0.2-0.3° Celsius.

Personal factors:

Now I know this is very different based on persons. I sleep best with very cold temperature. Very cold meaning near freezing. I have my best sleep at around 0-3° C I get better sleep values at -20° celsius compared to 15° C. I sleep better with a weighted blanket - but that requires for me a constant temperature at around 13-15° C - quite expensive to achieve in summer based on electricty cost - if you want some fresh air exchange for oxygen too. I monitor air quality with a CO2 sensor - and shutters/window are electronically adjustable to open by percentage should air quality fall too low (or better stay open slightly even with aircon running - as otherwise after about 1 hour in my small bedroom air is used up). I cannot use blankets above 17-18° otherwise I overheat. At 17-18° I would use a bedsheet or a knitted blanket (meaning with many holes to let air through) only. For me in the mountains in a tent the low temperature rating of a sleeping bag is perfect as comfort temperatue. I just produce a lot of heat at night. And no - I'm not overweight - body fat fluctuates from good periods at 10% to max 14-15% when i start dieting cause extra kilos aren't good for endurance sports.

Oh yeah - I of course already use a pocket spring mattress that is rated very well for hot climate.

I could try going waterbed - but that will be more noisy and I think aircon is the cheaper, more reliable solution as stiffness/softness can be much better dialled over waterbed/eightsleep or similar. Also eightsleep is out for me because of noise. I'm a sidesleeper and ear plugs annoy me when sleeping.

While i therefore sleep much better in colder temperatues - more important is to have the right temperature that doesn't fluctuate wrongy. If temperature increases too much I will wake up and it will destroy my sleep. So anything below 15° C. is in my bedroom sadly not achievable. Yeah i already placed a fan into the window to blow in subzero air during winter - but as soon as sunrise approaches the temperature increase then will make it horrible. Aircons just cannot reliably cool lower and I'm not allowed to install a venting system as I live in a flat not my own house and walls are owned by everybody. The higher the temperature the more correct it needs to be - at 0-5° I can just pull up the blanket a bit more - but at over 20° the sheet basically just acts as creating a more even temperature around the body.

I basically cannot sleep at all in 25° C. or more - so if forced to in a hotel without aircon, I will drop like 20 liters of water onto the bed to get evaporative cooling to a degree/better heat transfer through the mattress. That will make sleep possible but yeah not good at all.

Literally as soon as I want to go to sleep my skin temperature increases 1-2°. During the day I don't mind heat too much (rather average) but at night it's miserable for me. Strangely taking a short nap during midday/afternoon I can cope with heat better (yeah not as restorative as in cold, but I can fall asleep)- but not at night.

My girlfriend prefers it warmer - but usually when I sleep with a sheet, she already has a winter blanket. And if it's cold enough for me to use a blanket she has a heated bedcover that adjusts temperature based on proprietary loging and data from her apple watch. So she is covered and 15° is still okay for her. She will just use warm blanket and maybe a hot bottle to fall asleep. I often then later see her legs sticking out of the blanket or throw one of two blankets away at night - but she needs heat to fall asleep while I need it cold. So people are very different and I know I'm rather unusual.

Technological aspects:

How can I best set the temperature based on my heartrate? I have an ESP32 with bluetooth that directly gets the heartrate from my heartrate strap - as garmin watches cannot transmit in real time properly (yeah there is the broadcast option - but it's only available during activities - and I don't really know how to capture it with generic tools and get the data into home assistant). After hard sports average overnight heartrate is 10-15 beats higher than after a recovery day - so the simple feedback - the higher the heartrate the lower the temperate needs to be adjusted is the first factor.

The harder the sports was - the more the temperature needs to drop during the night - while after a relaxing day and eating very little - temperature maybe could even increase slightly over night for a good sleep. For waking up a slow increase in temperature is beneficial.

I guess adding an Emfit QS into the loop - but using heartrate via heartrate strap will give the best data - and then allow to build from there.

What I want to know:

Is there an tool I can use for analysis. Best some tool/software that can use the heartrate data and import sleep data from my garmin account. I cannot find anything really. Anything for home assistant that would to it?

Or should I just use the above and ask Claude/another AI to write me an automation for Home assistant and then I would adjust it manually myself?

Anyone with experience on setting up aircon temperature based on heartrate. Or maybe based on some other technical tools that aren't crazy expensive to try out.

2.5kw vs 5kw Wok induction burner

It's really hot the last few weeks so I don't wanna make a video showing the differences. But one thing is ace clear. You really need a high powered induction wok burner if you want to get towards high quality restaurant grade Asian food....

Pictured here is a standard 3.5kw (actually 2.5-2.6kw measured draw) on top wok induction burner 28cm diameter -4cm deep like you get around 100-120euros on AliExpress. Touchscreen is a pain in the ass and while it's leagues above the fully underpowered ones like Abangdun, Nuwave or other toys, especially the 120v versions, there's a huge step up to a 6000w (actually 5.3-5.4kw) restaurant grade unit.

That was my first buy but I just couldn't ever get it hot enough, tiny portions weren't even possible and the heated area with a ln effectively 22cm coil is too small.

So step up to a 6KW concave induction burner with magnetic slider. It again doesn't hit the real power levels but it gets to 5.3 or 5.4kw power. About 1/3 what I have seen and was allowed to use in a starred Sichuan Michelin restaurant in Shanghai for a dish and what I know is used by some high class restaurants in Taipei. Yes 15kw induction, foot operated power dial, and 46cm wok I've seen the chef do two portions at once, and get wok hei so good everyone would say they must have used a 200k BTU or higher gas wok burner. But with a little over actual 5kw power you can easily get restaurant grade wok hei without gas at home. You can dial it to the max for a few minutes to get oil actually self igniting but it's a bit of a mess indoors with fire alarms tripping virtually in your neighbours flat and even with great ventilation it will take a few hours for the smoke to really clear your flat.... What you do get that is virtually impossible on the small burner is crispy veggies, smoky taste from sauces/oil slightly burning off instead of half stir fried half steamed veggies which is about as good as you can get on the small burner. Price wise you look into about 160-170euros from Taobao or Alibaba,plus 30-40 Euros shipping, plus toll, plus VAT and plus the toll processing cost charged by your postal operator. All together like 300 Euros.

I have here now a 32cm, 7.5cm deep 6kw model with magnetic slider control. Yeah you could go for a dial but trust me the magnetic slider is much more intuitive and faster. The coil was wound at 26.5cm actual width but I plan to rewire it sometimes to 28cm or so to spread out the heat on the sidewall a bit more. But while it's easy to open the bottoms it's hard to take of the protective metal casing for rewiring the coil.

Yeah as visible in the introduction picture, you need a lot of space for it, and you will need to either hard wire it to 24A - 230v or you get a CEE plug combo so it stays mobile and your plug doesn't go up in fire... And you want at least 2.5mm² cabling or thicker all the way to your breaker box.

The wattages I measured are 500w on level 1 pulsing. 1000w pulsing on level 2, 2000w steady on level 3 then rather continuously up to 5.3kw. 500w is quite a lot for keeping dishes warm, that's not optimal but the pulsing is quite fast, so fast you cannot see it on a standard 1sec interval shunt meter.

The actual levels I use are usually 1,2,3 or 8. You don't really need any of the intermediary steps. If you want to keep something warm it's deciding 0 or 1... 2 is already easily hot enough to keep something cooking/steaming/frying and 3 is hotter than your Abangdun will ever get. Then whenever you need power it's flick the slider to max and get stirring fast. Yes you still may need to cook even single portions in 2 batches. Otherwise you end up with some ingredients burned with others just starting too brown. Say Sichuan green beans I make a single portion in two batches for the beans on max heat, then fry the rest on setting 3, then add back both portions of beans, up to max and add the sauces and dry it off.

What you do get is really crunchy veggies and meats that have nice char to them. Something basically impossible on any gas burner <50K BTU, and impossible on all the consumer grade induction burners.

What is not too like besides the size and the electric side? You really need a wok that fits. I always prefer my Yoshikawa 36cm over my Oxenforge 34cm for ease of maintenance and cleaning up. But the Oxenforge has a too big cold spot right in the middle here because it is too flat and bigger. The Oxenforge still has a small coolish spot of 3cm diameter or so right smack in the middle but that is not a worry. You would not be happy on a 36cm Oxenforge I believe as it will sit too high.

I somewhat need to hammer my yoshikawa into form, but not sure that will work smoothly. Too bad yoshikawa has no fully round version.

I've added some water boil pictures to show the difference. Yoshikawa has the additional handle, Oxenforge doesn't.

So yeah, you don't want a too thin wok on induction. You will inevitably miss some reactivity Vs gas an super thin wok, you will not be able to toss food, and you really need to find a wok that fits nearly perfectly. So get a 36cm diameter induction wok for 36cm wok. I'm not kidding for those 7-8cm deep cookers. The big advantage over the 4cm deep ones is much better heat up the sidewalls. You want it deep but it will make wok selection hard.

And why not save 10-20euro and get a version with knob? It's much harder to get the knob from 8 two 3 and being sure you hit 3. Any second you need to check is degrading your food.

So vs dedicated wok gas burners. I would say it beats any 50k BTU dedicated burner. If however you can install a 100k or stronger BTU wok burner, cook outside, it beats the induction burner here. My kitchen only has 25A-230v, so I cannot get a 18-20kw induction burner and the crazy ventilation you would want for it in my kitchen. This is the best compromise for me. It's a huge step up from the smaller old so called 3500w induction wok burner. But there's still enough moments where I would just like to have those 20kw instant firepower. Actually the chefs told me they prefer their 20kw induction over gas for indoor kitchen. They are even faster than 200k BTU gas, you don't have bad air quality and for their health it's just much better. Outdoors go gas, indoors just go for the biggest induction burner you can afford. It the pros can get a Michelin star for a Sichuan restaurant serving loads of stir fry dishes, you don't need to compromise your health and use a gas wok burner indoors. Also with gas you can use any kind of wok and showcase your tossing. You'll learn however to move food with spatula not much worse.

Oh yeah - takes about 5 seconds for my 2mm Oxenforge 34cm to hit 250° Celsius when empty. It took 15 seconds on the small burner. Even though it's only twice the actual power, it's three times as fast empty as there is less time for the wok to lose heat to the air.

Oh and another plus, it doesn't stop ever if you take the wok off. Cut power, plug it in it will always directly fire away on the level chosen if a wok is present. I think the consumer grade all stop and start making annoying noises to remind you they are on. Restaurant grade means your job to switch it off. No standby nothing. As soon as the metal gets contact it fires away.

Bartscher for example has a 5kw model. I'm sure it's good but the touch controls simply destroy it. That's why for a 3.5kw model I think GGM Gastro is as good as it gets (the one with a knob dial, they also have a touch one). Deeper is always better but makes it more problematic fit - meaning harder to choose the right wok.

Drehzahl Lüfter Außen Gerät je nach Verbrauch, Outdoor Silent mode wie hoch?

Sorry - Domain war im Screenshot daher erstpost löschen müssen und repost.

Bekomme das Firmware Angebot irgendwie nicht angeboten - weiß jemand welche Drehzahl beim Outdoor Silent Modus sind bei minimaler Last?

Drehzahl je nach Anforderung:

848 - bis etwa 150w im 1% Mode (46db)

944 - bis etwa 200w im 1% Mode (49db)

1080 - bis etwa 350w im 1% Mode (52db)

124x - bis etwa 680w im 100% boost mode (56db)

Lautstärke gemessen in 2m Abstand etwas seitlich vom Luftstrom (im Luftstrom selber nochmal 3db mehr, vernünftiges Messgerät db(A). Allerdings in 18m² Raum was die Lautstärke erhöht wegen Reflexionen. Mindernd jedoch der Fakt dass ich den Grill weggeschnitten habe sowie innen die Aufhängung selbst gebaut aerodynamisch korrekt statt mit den Alu Profilen die laut sind - was etwa 3-5db die Lautstärke senkt. Mein Patio zum Kleinen Innenhof ist noch lauter und das ist das Problem. Nachts darf es in 1m Abstand zum AG maximal 35db haben (Tirol, Wohngebiet, Lärm Verordnung).

Mehr power bekomme ich im Kühl Modus nicht hin bei 20/24 Grad (innen/außen)

Ob die angezeigte Drehzahl korrekt ist, kann ich nicht prüfen, aber es sollte halbwegs passen wenn man die Lautstärke im Vergleich misst. Steigt ziemlich exponentiell zur Drehzahl an. Bei 650 wäre es wohl halbwegs nutzbar für mich. Ohne Silent mode Brauch ich sie gar nicht rausstellen. Die Lautstärke ist in 18m² Zimmer gemessen. Am Balkon im Innenhof hallt es noch stärker.

Für die Drehzahl musste ich in Home Assistant erst die Anzeige aktivieren. Kam bei irgendeinem Update der Integration, und war per Default inaktiv.

Alle 30min in etwa (wenn 120w Verbrauch) kommt das hoch drehen zum Öl Rück pumpen auf etwa 500-600w und zumindest 1080 Umdrehungen. Wird das im Outdoor Silent mode eigentlich besser gelöst ohne hochregeln von außen Lüfter? Weil während es innen am Kompressor ja nötig ist könnte außen alles leise weiter laufen, in den 30sek geht die Temperatur ja nicht kritisch hoch.

For Europeans - finally a quality cheap induction 3.5kw burner

Stumbled over this: https://www.ggmgastro.com/de-at-eur/kochgeraete/geraete/mobile-tischkochgeraete/mobile-induktionskochfelder/induktionsherde-ids

That's actually cheaper buying them from Germany Vs getting the Chinese original on AliExpress. 165 euros plus VAT vs around 180 on AliExpress plus vat for something very similar (and 2 months shipping on the slow lane - as it's cainao for heavy goods which means either rail or freightship)

165euros for an I think actual 3.5kw unit in the 165mm height bracket with knob power control is great. Those are restaurant/catering grade and the shop is pretty well known in catering..

Definitely a level over the cheap Bartscher unit... Too bad they don't sell a 5 or 6kw one - but this is about the very best Chinese 3.5kw burners you can get, and buying it locally means even some sort of warranty unlike AliExpress. Yeah they are just some branded Chinese ones I think, but this is the highest quality 3500w package you can get and I think they actually hit 3500w unlike the smaller ones that actually only have 2500w with horrible electronics... Or could they actually

Actually they have mobile flat induction plates too which likely blow any of the cheap ones with undersized coils out of the water.
