Aqara W200 fan mode via scene sync workaround

I briefly had ecobee and there are limitations when using it as a HomeKit device integration vs using the W200 with the matter over WiFi integration. My W200s are on LAN only VLAN with no internet access. I was able to provision them without the Aqara app as it can be setup completely via the screen. If you want to use the W200 as a matter hub for Aqara devices (which cannot be added to non Aqara hubs) such as the U100 lock then you do need to initially expose it to the internet and use the Aqara app to add the thermostat and lock. After that you can block the internet. So now everything is …

… don’t need multi-sensor averaging. This is coming post-launch, so wait until it’s updated if this is important to you. First a few things: - despite its hub having Thread, it actually connects the thermostat via Matter over WiFi. - Aqara app not needed for setup. - works with internet access disabled. However, I did detect clock drift on the W200. I addressed this by adding a local ntp server in the DHCP options on my DHCP server…which I can’t believe I had forgotten to do! Basic HA functionality is: - climate entity with controls for setting cool/heat/auto/off modes and up/down temps. …

Aqara Thermostat Hub W200 - Real-world notes. I recently swapped out my ecobee Premium for the Aqara Thermostat Hub W200 and wanted to share some real-world notes after using it for about a week, especially from a Home Assistant perspective. Setup was straightforward. I added it through the Aqara app and then paired it to Home Assistant using Matter. It shows up as a standard thermostat device with temperature, humidity, and HVAC mode controls. Nothing too surprising there. One thing that is actually more useful than I expected is the built-in screens. You can add up to six extra screens with …

Unfortunately, fan mode is not passed through Matter. Hopefully, this gets implemented in a software update. There is a workaround, but it requires initial setup in the Aqara Home app. You create a “scene” which is a virtual button that triggers an automation. You then enable ‘scene sync” through Matter. This creates a virtual switch that shows up as a connected device under the W200. You can then use that to set the fan mode. Options are: * fan auto (normally idle, on when ac/heat is active). * fan on. * fan timer (min). * fan cycle (min/hr). Other things can be passed through scene sync, …

Just want to add some additional notes for other people who may be looking. If you have a 2-wire radiator boiler setup it may not be worth it to switch over. I switched over from a Nest, and It does not do the "power-stealing" that the Nests and (i think) ecobees do. I ordered the adapter and have been talking to support all week on how to get the nest thermostat to power on for me
