I spent longer than I’d like to admit integrating this AC with HA. But the end result is spot on. I assume the mapping I obtained will be the same for you. If not, here’s my approach so you can perform the same if needed.
- On the Tasmota Console run weblog 4. This provides debug info to the console.
- I played around with the settings on the AC and observed the messages back (Tasmota debug).
- From there I determined what responses I needed to send back to HA for status updates. Unfortunately these DpId formats didn’t match the syntax described on the blakadder site.
- I wrote a catchall Tasmota rule that will send the MQTT messages out with the relevant data (Tasmota Rule1). It sends as stat/topic/DpId with hex formatted value (0x…). I deal with the mapping of these on the HA side.
- With that same info I determined what tuyasend<x> commands could be used to control the unit.
- Getting HA to send the relevant commands over MQTT proved difficult. I could only get Tasmota to listen to MQTT Events, and I couldn’t find how to manipulate HAs MQTT climate integrations outbound data. Fortunately all message data proved unique, so I squeezed in the mapping for all possible combinations (Tasmota Rule2 and Rule3)
- I included the serialsend5 command as per the blakadder details. That forces all values to be queried and sent back to HA via Rule1. I also listen to an MQTT refresh event on the AC which I can trigger from HA if needed to update status. I have a HA startup automation that fires this.
- The HA MQTT climate setup is pretty self-explanatory. My unit is named ac1 in the below. State topics are mapped to the DpId. The temperature values required hex to decimal conversion, and the other values are just straight templates.
- Only shortcoming here is that the mode of the unit always reports cool, fan_only, dry or heat. It won’t report off. For this reason I have commented out the mode_state_topic. Given control is typically via HA anyway, this isn’t proving a bother to me.
- Put weblog back to 2 on Tasmota when you’re done, weblog 2
