Thermostats compatible with selfhosted Home Assistant (lemmy.world)

Hi! I am running Umbrel on a Raspberry Pi 4 and I have "Home Assistant" installed in it, I oly have some smart lights connected to it. I would like to integrate a Thermostat with HA. But I am a bit overwhelmed with the different types of connections (Z-wave, Zigbee, Wifi, ...)

Do you guys have any kind of recommendation, what connection is better? I would like to keep it local (or connecting remotely via Tailscale) but I would like to avoid any cloud or third-party server solution.

What thermostat hardware can I buy?

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters
HA Home Assistant automation software
~ High Availability
MQTT Message Queue Telemetry Transport point-to-point networking
Zigbee Wireless mesh network for low-power devices

3 acronyms in this thread; the most compressed thread commented on today has 8 acronyms.

I'm currently using a Meross thermostat as it was relatively cheap: https://shop.meross.com/collections/smart-thermostat/products/matter-smart-thermostat-mts300ma

Currently using the meross_lan (https://github.com/krahabb/meross_lan) integration to make it work because my LAN doesn't support Matter.

Definitely Zigbee or Z-wave instead of wifi. Once you start to build out more devices you will be glad to not have gone down the wifi route.

I went with Zigbee and have Sonoff SNZB-02 temperature and humidity sensors in each room that have been absolutely flawless since the day I installed them, and they last about two years on a single battery!

I would obviously recommend them but I don't have any experience of other thermostats or of Z-wave.

I did also install smart Zigbee TRVs on each radiator but I don't rely on the internal thermostats of them as they don't accurately represents the overall room temperature.

If you're just starting to build out, what about using thread instead of zigbee or zwave?

[–] jellyfishhunter@lemmy.world 1 points 2 hours ago

I second that solution. I've built the same setup for my home last Christmas, even tried different brands of TRVs to see which one I like. Works perfectly well with a Raspberry Pi with Home Assistant. The only issues I ran into were my lack of experience.

That is the one you want. Honeywell t6 pro Z-Wave version, specifically that link which is the newer Smart start version.

Z-Wave is 100% local, not Wi-Fi, and secure.

I use these in my house and couldn't be happier.

I like this one but I’m not sure why a $5 microcontroller, 4-5 relays and a screen costs so much. And it’s not even a great screen. I kinda like it to be more of a full color LCD screen. Just my opinion.

[–] a_fancy_kiwi@lemmy.world 1 points 2 hours ago

The house I bought had one of these installed already. Works great with the homeassistant ZWA-2 antenna.

[–] MaceyDay@lemmy.world 4 points 3 hours ago (1 children)

Another vote for this option. I've had mine for three years and it's been rock solid. I'm not using the built in schedule, I'm controlling everything through HA

[–] avidamoeba@lemmy.ca 1 points 2 hours ago

And another vote for it. It's been great. The only thing I miss is it doesn't have multi-speed support but most setups don't have multi-speed motors anyway.

[–] osaerisxero@kbin.melroy.org 3 points 3 hours ago

The other recommendations are good, but please please double check your tstat wiring and/or HVAC system to ensure they are compatible. One of the few stats that work with my system without shenanigans is the Honeywell T10 Pro (which also worked out of the box with HA). This required me to rewire the control run to use it, and is not something I would recommend for people who aren't prepared to cook the control board on their furnace if they do an oopsie or regularly read electrical diagrams.

@orosus

i use a hive thermostat & a variety of radiator valves (hive, aqara, sonoff), all #zigbee & compatible with #homeassistant through the excellent #zigbee2mqtt.

[–] Ludicrous0251@piefed.zip 1 points 3 hours ago

They're all generally fine. WiFi thermostats open up more security holes than the others because they are designed to be chatty. I have an ecobee WiFi thermostat that's isolated to only talking to HA locally using the HomeKit integration, which is fine, but I can't say I'd recommend it.

When I set up my thermostat the ZigBee/Z-Wave options were quite frankly ugly and had limited wiring compatibility. Nowadays there's a bunch more options on the market - you should be fine finding what you need anywhere.

ZigBee/Z-Wave/Thread are all pretty comparable, so I'd go with whatever you already have on your network - me personally I'm all in on ZigBee right now so I'd probably get one of those.

If you're undecided, HA newest official hardware supports ZigBee & Thread so I'd go with one of those.

[–] CompactFlax@discuss.tchncs.de 2 points 4 hours ago

Depends on what you’re controlling and your geographic location.

[–] Windex007@lemmy.world 1 points 4 hours ago

I think you can use home kit ones locally... which really broadens your options

[–] UnrefinedChihuahua@lemmy.dbzer0.com 1 points 4 hours ago

GoControl GC-TBZ48, 6 years and running, not a single issue. ZWave.
