Aqara W500 floorheating thermostat

Hardware
1

Hi, I see that the Aqara W100 thermostat is supported bij zha and z2m, I’m looking at the W500 since it has a dry contact (and mains powered)

I plan to use such thermostat to control a electric 900W radiator in my kitchen

Does anyone know if this or will work via Zigbee or Matter over Thread with HA?

I don’t fancy getting a aqara hub :wink:

Alternatively I might get the w100 and a shelly to control it

In my experience, Aqara products work well with Zigbee. I dont have experience with that thermostat though.

Not fully supported yet over Z2MQTT yet.

Yes, I am still waiting for the support as well. Especially because I wanted to fully test the device or return it, if it’s not doing everything I am looking for. I did not think that it would not be supported by now, since the W100 is for some time already.

Its now supported by Z2MQTT :slightly_smiling_face:

Thanks for sharing, I opted for a different solution to control the radiator (less wiring), I was planning to use now the W100, in the assumption that that would give me a binary sensor ‘heater-on’ but unfortunately all these extra params are not available via thread, only with Aqara hub. I returned it :pensive:

I now operating it with a Sonoff zigbee temperature sensor, a Shelly 1PM mini and a virtual thermostat in home assistant. missing the ‘manual’ control though

maybe if the Aqara W100 gets more elaborate support in HA i can still adopt my system.

Aqara W100 has Zigbee support and work pretty well and is nicely customizable. You can use external temperature sensor as well or virtual one which can be controlled on W100 with +/- buttons as a target heating temperature for e.g. I have 6 of W100 and all works great for last 3 months so far.

are you using the W100 with ZHA or Z2M?

Im using it with z2m

Just installed the W500 as well. Trying to connect it to HA, but it’s not working smootly yet. I tried Matter first, it starts the configuration but ends in an error. Then switched to Zigbee (ZHA), and I can connect it. However, not all entities are really giving correct values, and I can’t click on the device (HA will freeze).

Is this model just too new for ZHA or Matter?

Edit: I just noticed the Power entity doesnt display the correct values. It says 30W, but actually it uses 300W. This is the case when using Zibgee with ZHA.

Edit 2: Added now through Z2MQTT. Works great, the only thing I am missing now is the Power entity. I would like to follow the energy used.

I have the Aqara w500 in Zigbee mode, integrated into Home Assistant through Zigbee2mqtt.

Things work relatively well and I have automations cycling through the different presets. However I cannot, for the life of me, figure out how to customize the temperature for each preset! Neither through the exposed variables nor through the device itself.

Any ideas? :grimacing:

Thanks!

For ZHA users: I created an initial quirk for ZHA: [Device Support Request] Please add Aqara W500 Floor Heating Thermostat · Issue #4412 · zigpy/zha-device-handlers · GitHub Mostly it do same things as Z2M converter.

Hello :slight_smile:
By curiosity how did you swicthed the aqara w500 in zigbee mode ?
i wanted to buy it, but i read in some comment that without Aqara hub it cannot be switched to zigbee mode.
And so not possible to add in Home assistant.

Hey Ben, I was having the same question as you, you need to configure it with the Aqara app, to change it to Zigbee mode. It uploads a new firmware to the device

16

I have the same problem as you in Zigbee ZHA mode, it crashes HA …

17

Thanks for the reponse ! :grin: just one element to be sure, in order to configure it in Aqara app, do we need to have an aqara hub ? (or can we do it through another thread border router for example)

18

If it’s anything like the latest Aqara products (like the H2 switches), then you only need the app to switch from Matter to Zigbee (& vice-versa). No hub required.

Try it out yourself - the only thing it can cost you is 5 minutes of your time.

You don’t need the Hub to change it from one mode to another, just the app.

If you want to use it as a Matter device, you need a Matter hub
If you want to use it as a ZigBee device, you need a ZigBee receiver

It would be great if Home Assistant would get support for the Aqara W500 over Zigbee ZHA. I was looking for exactly such a device. My first hit was a Salus Quantum SQ610 but although it has zigbee support it is vendor locked to their own hub. The Aqara looked like a great alternative, until I found this topic. :sweat_smile:

This works, very good!!

This is great. THANK YOU!
