ESPHome: Climate Template for a Dometic RV AC Unit

Hi!

Not sure if this is the right place but…

I have HA in my camper van working great. I have a custom ESPHome device talking to my Truma heating that also works perfectly! It displays the various entities BUT it also exposes a Climate entity with the Horseshoe temperature control and and some buttons for changing fan mode etc.

Now I also have a Dometic AirCon unit that I would also like to control similarly.

The AC unit has BLE control and I have been able to write a YAML file for another ESP device with which I can control all the modes, fan, temperature etc. through HA. Still a bit of a work in prgress but mostly there by sniffing the connection!

However, I would like to present the data similarly to the Truma heater with a climate device but have hit the buffers! I cannot create a climate template in ESPHome 2026.
Is there a way I can combine my device data - sensors etc - into something that HA will interpret as a Climate device and present the climate graphic horseshoe entity does anybody know? Or will I have to go down the custom componengt route in Git :frowning:

You don’t need Git to build external component… :wink:

Did you take a look at what this can do yet?

It’s probably worth sharing some of your config too.

hey @soram , thank you very much for taking up this work! I am looking forward to also running my Dometic AC on ESPHome. Would you kindly share what you already made working so we can iterate on that together in the community?

best
