WLED 16 and LED Matrix Panels in Home Assistant!
You can display practical information from Home Assistant on LED matrix panels like this...
OR draw on it and add gifs of your dog! Haha! WLED was updated to version 16 recently, and the Pixel Forge tools are fun and easy to use even on four 64x64 HUB75 panels in a 2x2 (128x128) orientation!

Also, big shout-out to u/Frenck for creating and maintaining python-wled and the WLED Home Assistant integration. Since switching from WLED-MM to WLED, we're now able to get WLED updates directly through Home Assistant, which is awesome.
I need suggestions for a water shutoff valve that must be plumbed in.
My Dome Watermain shut off, just died. I need to replace it but I don’t want to do the same thing as before, strapping a device on my water main valve. I want my water main valve completely unobstructed and in a state that is dead simple to shut off. The shut off must be completely separate.
I want to plumb in a valve just down the pipe from the water main. I’d appreciate any tips, advice or recommendations on products that you have experience with.
I want to stay away from moen because I have heard that they fail after 3 years and are prone to false positives.
Reliability is my #1 concern.
Right now I’m looking at Solid motorized valves. But I don’t know the best relay to use with them etc. is this a bad idea?
what have you been using?
Any tips would be great. What issues might I run into? what don’t I know that I don’t know?
Which Smart Water Shutoff Valve?
Currently building a house in the FL panhandle. Hot sun, salty air, and the exterior walls of the house are ICF with 6” reinforced concrete. The house‘s main water supply will be located outside the house. All piping is PEX-A.
So I want an in-line outdoor “smart” water shutoff valve that can withstand the elements, doesn’t rely on WiFi or cloud connection, and preferably doesn’t need AC main power (don‘t want to run a cord from the side of the house where the water main is, to the nearest ac plug on the patio around the corner). My “smart“ home will be run via HomeAssistant.
I researched Moen Flo, Phyn, Rheem, FloLogic, EcoNet Bulldog, and YoLink. I’ve narrowed it down to the Moen Flo or one of the YoLink Smart Valves (not sure which one is best).
Pros:
- Micro-leak detection
- Automatic shutoff
- Insurance savings
- Integrates with HomeAssistant
Cons:
- Plastic turbine design
- Subscription paywalls
- False alerts during high use
- Requires ac power and Wi-Fi
YoLink X3 Valve Controller & 3/4” DN Series Motorized Valve
Pros:
- Long Battery Life
- Offline Reliability (Control-D2D)
- Superior Materials
- Full-Port Flow: Features zero bore reduction, meaning it causes no reduction in water flow.
- Long Range LoRa Tech
- Integrates with HomeAssistant
- Separate Controller from Valve (could also be a con)
Cons:
- Outdoor Limits: While the valve is weather-resistant (IP67), extreme environments still require careful placement to protect the controller and battery compartment over long periods.
YoLink Commercial Grade Smart Motorized Valve
Pros:
- Long Battery Life
- Offline Reliability (Control-D2D)
- Long Range LoRa Tech
- Commercial-Grade Build
- Flexible Power Options
- Integrates with HomeAssistant
Cons:
- Sold out for several months (discontinued?)
- Controller and Valve together (co 1. Moen Flo
Pros:
- No monthly fees
- Long-range LoRa tech
- Offline functionality (Control-D2D)
- Ultrasonic accuracy
- Integrates with HomeAssistant
Cons:
- Reduced volume/pressure: due to reduced inner diameter for flow monitoring.
PSA verify that your Smart water valve is actually able to shut off.
My dome water main shut off stopped working. I have no idea how long it had been bad. Luckily on a whim I decided to test it. It failed. Was slow and couldn’t close the valve all the way. At first I thought that it might have been a bad power supply so I swapped that out. Nope same story. When I took it off I was able to tell that something was wrong mechanically. The the flat sided bolt stripped out of the part that connects to the valve handle. So it couldn’t get it to tight all the way. I was very anal making sure that the Dome was properly aligned. With the valve. I think it’s asking a lot of the small amount of metal to the side of the flat sided bolt to handle that much torque. Anyone have a good suggestion for a replacement? This time I want to put in a valve separate from the main that isn’t just tacked on.
Random HAOS Reboot
Took a dedicated Windows 11 machine (Intel NUC) and installed HAOS. It now randomly reboots every 5-10 minutes. Hardly anything loaded on it. Just clean HAOS. Anyone experience this before? Works perfectly fine running Windows 11.
Tablet Display
For those that have a fully functional tablet display, I'm very curious as to what you learned worked well and didn't work so well.
Ours is intended to function more as a family hub, so things like calendar, grocery list, recipes, birthdays and bills reminders, and possibly some YouTube
Does anyone have any tips and tricks to enable a really effective and streamlined tablet display and function?
MCP Server - which one?
I want AI to review, clean up and possibly rebuild my HA instance - entities, dashboards, automations, the works... I don't need it for any kind of voice or natural language control of my home just yet... just to clean up the mess that I built over the years and make it better/prettier/stabler.
I've looked at YT videos, scoured github and searched this forum and the Facebook forum, but the AI world moves fast and hard, so it's hard to find up to date info.
So what does the (human) hivemind suggest is the best MCP server plugin/integration to use to achieve what I'm trying to achieve?
Ceiling fan with light switch
I have many of these switches around my house I would like to replace (wifi, zigbee, zwave, doesn't matter). The right switch is a toggle for the ceiling fan light and the dimmer slide controls fan speed. The left switch controls an outlet in the room and I will be removing that functionality so open to replacing that switch or wiring it to another function.
Any suggestions on the best route? My wife will naturally be replacing all ceiling fans in the near future as well.
This was a journey, but now I have a HA alarm clock
Getting here was a journey. This is an IOTTime clock from Aliexpress, that needed to be disassembled to get to the solder points I needed to connect a TTL UART adapter to before I could even talk to it. Then building and flashing Tasmota thanks to this person's work. Setting up MQTT, helpers, automations, and dashboard cards in HA.
Now it:
- Is fully controlled including presets from a HA bubble card popup card.
- Has physical button controls for showing current alarm, enabling/disabling current alarm and a spare button I haven't found a use for yet.
- Triggers a gradual room light automation 30 min before.
- Handles DST and time sync itself, unlike my current cheap backup alarm clock that needs to be manually set and will drift and eventually overlap my smartwatch alarm.
- Let's me send custom alarm sound sequences not actually tied to the wake up alarm, which I can tie into other automations. As an example, one courier here drops mail in the mailbox during the night, so I want a toggle I can turn on for expensive deliveries to wake up and grab it when the mailbox sensor triggers rather than leave it sitting out until morning.
In the future the plan is:
- Extract alarm timer from my smartwatch, add 5 minutes, have that be the automatic backup alarm.
I'm at my whits end, if anyone else did set up an Midea AC unit please tell me how because this can't go on when, without HA, the AC it's doing it's job properly.
Update to 2026.8.2 broke remote access
I've recently upgraded from 2026.7.4 to 2026.8.2. I did so remotely while being away a few days (yeah stupid, i know) and after updating i lost all remote access.
I'm using both the cloudflared addon and the tailscale addon and am running HomeassistantOS on a Pi 4. I can see in the Tailscale dashboard that the last time the device was seen was right before the update and i cannot access homeassistant or any other device from that network through the vpn/taiscale anymore. Cloudflare just gives a 1033 error.
I know homeassistant is still running, because i get notification from automations on my phone (probably because those run through google services). I've also rebooted the system completely through a smart switch, but that also didn't help.
I can understand something breaking with accessing homeassistants frontend in the update (even though the changelog mentioned that the new network settings would migrate automatically), but both OS and Supervisor were already up to date, so i don't really get why tailscale would stop working. Atleast i thought that Addons/Apps were somewhat independant of homeassistant.
I'll see what had happened when i'm back, i'm just wondering what exactly could've caused this.
Setting up Echo Spot for VACA
Hello! I have finally gotten my jailbroken Echo Spot set up comfortably with View Assist Companion App and I would like to share my configuration if anyone wants to replicate my result!
- Zoom level: 1.0
- Wake word threshold: 5.0
- Wake word: Alexa
- Wake word sound: Alexa
- Wake word engine: OpenWakeWord(onnx)
For the device itself, I downloaded the companion app from the GitHub and I logged in with a special account for the device. For this account, I set the default dashboard to be hidden and added an analog clock with the following configuration:
kiosk_mode:
hide_header: true
views:
- type: panel
path: ''
cards:
- type: clock
clock_style: analog
clock_size: large
show_seconds: true
no_background: true
border: false
ticks: hour
face_style: markers
seconds_motion: continuous
time_zone: America/New_York
date_format:
- weekday-short
- day-numeric
grid_options:
columns: 12
rows: 4
icon: mdi:circle-double
To edit the dashboard later, use "?disable_km" in the url. The only downside I have with this device is that when I press the power button (previously the mute button), the screen can mildly flicker sometimes. That is solved with a restart, but important to look out for. So far i'm liking it, but does anyone have an easy way to change the clock hand and text colors?
Google Home replacement?
So as the title suggest, I want to replace google home, its current use is to just control some devices but because of Zigbee stuff I cannot control those and I want to.
What's the simplest way to control zigbee items staying true with homeassistant, no cloud BS. local control without spending too much?
AC battery storage with local Home Assistant integration?
We are looking for a solution where we can add an AC-coupled battery to our current PV setup. First priority is to have a good HomeAssistant integration (either via Modbus or a local API) working locally as we live in Germany and do not want to rely on some vendors’ cloud which might go down and erase our data / automatons forever.
It’s mainly about being able to make some automatons from HA like starting your washingmachine whenever you battery is full, controlling how much you charge/discharge depending of electricity price etc…
Hey all! Anyone here running an AC battery (with HA) in germany? Which one and which protocol modbus or api local?Also just wanted to ask about the SB Max ac, does anyone have experiences how well it works locally vs only working via app/cloud? It says it can connect to various apps. But i havent gotten further than testing for compatibility yet. Any input would be great!
You could say things are going pretty well for my cpu usage
Sensor for current light temperature
As the title states: I want to make some of my lights flow better with the current outside light conditions, but adaptive lighting doesn’t really cut it.
Does a plug and play sensor for measuring ambient light temperature exists or am I looking into understanding esp32 and everything else that follows to make this come true?
Harbor - Home Assistant Integration
u/DivergingDog built a Home Assistant integration for Harbor that was recently deployed https://www.home-assistant.io/integrations/harbor/
Harbor started as a baby monitor, but we’ve been pushing it more toward a general monitoring platform.
You can use the same system for a baby, an aging parent, or someone medically fragile. We have nurses on staff who can monitor medically fragile family members (as an optional service), and the vision and word-detection AI lets you create open vocabulary alerts for whatever you care about instead of choosing from a fixed list.
A Home Assistant integration has always made sense for us, but we didn't have the expertise / HA experience internally. Community dev u/DivergingDog did all the work on the integration. We just helped where we could. Harbor is modular by design (you can add as many Cameras or Monitors as you'd like), so we wanted to be able to plug it into everything else people already have in their homes.
More entities and support coming in the 2026.9 release, and even more after that.
You can learn more about Harbor on our website.
Thanks for any interest 🙏
Seriously messed up GPS
This is my Homeassistant tracking. A lot of Home-Jumping, whil my Google maps history shows none of it. High Accuracy mode is ON (all the time), due to a bug(?) in the zone-detection of the Companion App. Maybe its the reason for the jumps, but actually I would assume location to be BETTER than WORSE with "High accuracy mode"...
Anyone with similar issues or ideas?
