Again, the problem is not Wi-Fi or that the devices use Wi-Fi to communicate. The problem is the protocol that they are communicating with. You can’t immediately say that any Wi-Fi smart home device is inherently bad just because it uses Wi-Fi. Wi-Fi is synonymous with cloud control, but more and more products are including Wi-Fi and local control, including some official standards like matter and MQTT.
Can you at least cover up the wall switch?
Search Amazon for TUYA thermostat. I found options for as low as $25. If you want something that’s actually going to be a good product, the Amazon thermostat is good I guess, it just is insanely walled off from everything else. Something that is worth considering as an alternative is the Wyze thermostat.
I wonder if this is how they subsidize EUFY and soundcore. Soundcore is another sub brand of anchor and they make quality Bluetooth speakers for a cheap price, but yeah… UFY pulling crap like that is not great. Makes me not want to buy anything other than soundcore speakers from anchor. Ridiculous! They also pulled HomeKit integration from their latest devices. Also ridiculous.
MOES has a Zigby hub. Otherwise, you might just be able to pick up an echo fourth generation and pair your devices directly with that.
It doesn’t look like that hub supports Amazon Alexa. It only supports Google Home, and apparently there’s an updated version that supports Apple HomeKit.
I’m guessing that you have a Smart Life Zigby hub? Check the specifications of the hub to see if it works in the Smart Life app.
I’m not sure if home assistant allows you to create a virtual thermostat entity or something like that using a separate temperature sensor and smart relay, but if it does, then this will work.
