If the Tuya cloud integration is too limited, there is an alternative solution - purchase a cheap Tuya IR blaster, and control the AC this way - 100% locally.
Search on AliExpress for "Tuya IR Zigbee"
Make sure you order a Zigbee model.
Hi,
I was able to make the integration working but it turned out that it is very limited so Im able mostly to switch the air-condition unit on/off. I was thinking that it will be able to switch on/off + at least to change mode cool/heat and set temperature but it looks like it does not work. I will look at tuya ir - thank you for good hint
