i dont want to drill into the roof using this EcoWorthy kit.
OR is there a way to hold the skinny 1.5 inches rails down with 4 cinder blocks?

efoil vs jetboard

i see both are same price. seems efoil is bulkier with the fins underneath. a jetboard looks more compact. so why 1 over another?

anything like Pila without the high price tag?

i really like the slim design but $1500 for 1.6kwh battery is outrageous! this is double or almost triple an Eco-Flow. is there anything out there that is almost flat like a Pila but without the high price?

here's a Pila battery in case you havent seen it

how to prevent NEMA motors slipping?

i got these nema motors to lower/raise my shades thanks to this video https://www.youtube.com/watch?v=NSV8zTLBukQ

the problem is, my window is really big. the motor can lift easily. but during lowering the shade, the weight of the shade will cause the shade to spin faster than the motor can control.

is there any way to prevent weight of the shade pulling on the motor? or do i need a bigger motor? if so, what type will still work with the driver and existing code? (i dont know how to code yml)

what are these contacts and how to add 2 wires to them?

this bluetooth remote controls a smart roller shade, using a proprietary protocol. i want to add relays to it so the remote can be automated with Home Assistant as seen in this video https://www.youtube.com/watch?v=glp2w6chl8I BUT as you can see, this remote does not have any "normal" momentary button. it is still momentary but super flat. i peeled back the sticker holding the almost flat metal button. for button labeled K55 as shown by the green arrow, i need to add 2 wires as shown by the red arrows to a relay. i confirmed by shorting the 2 red positions with a paper clip. the 2 contacts do not appear to be metallic so how do i solder 2 wires in? they are dull black instead of the usual shiny silver contacts.

desktop into smart plug to prevent turning on?

i dont know why my Win10 desktop randomly turns on, especially at night as seen here.

is it safe to plug desktop (1000w power supply) into a smart plug (10 amps)?

the automation will be if time between 11pm and 5am, do not turn On plug.

POE doorbell cam, aqara g400 or reolink?

aqara or this reolink for doorbell cam?

looking for something that works great with Blue Iris and off course HA. im guessing Reolink is the solution but not sure if there are other options. Unifi is not because i have never seen in stock. ebay selling unifi over $500, is over my budget of $300.

SavvyCAN's Playback does not work. any idea why?

i tapped into my Hyundai Ioniq 5's B-CAN bus. while i was in the car, i pressed buttons to lock/unlock, fold mirrors in/out, roll windows up/down. saved the CSV file.

next, i chose Send Frame and Playback. loaded the CSV file to replay. only lock played back fine and that's how i found the command to lock the car's door. any idea why the lock, mirror and windows commands did not work during playback???

automation on esp32 for CAN bus not working

i dont understand why this simple automation using ESPHome does not work: https://pastebin.com/5BcXeSZQ

IF doors are closed and unlocked, start 3 minutes timer. sadly after 3 minutes count down, the automation does not auto press the Lock button for me.

off course if i press the Lock button on the web gui, it works fine. and the same automation set up in HA works fine.

the ultimate goal is to have the automation on the esp32 chip work by itself, independent of HA.

any idea what's wrong with my yml file?

Can esphome run independently of HA?

I was able to get my car's doors status (close or open, locked or unlocked) into HA via esphome CAN bus. I got the esphome to send the lock command to lock the door in HA. Then i got an automation in HA: if door is closed but not locked for 2 mins, lock the door.

Can I set up the same automation in esphome so that the esp32 chip would lock doors in the middle of nowhere, without wifi ? If so, how?
