I have a Rinnai AC which uses the ELECTRA_AC IR codes. As mentioned here Ballu also uses ELECTRA_AC IR codes. I was able to use Ballu as the IR Remote Climate in ESPHome for sending and receiving.

@schlumm I can only get fan and mode but don't have any degree +- interface...

omersht · 2024-10-02T07:19:36Z

I am too not getting any temp control, have you managed to solve that?

mickeyva · 2024-10-02T07:28:52Z

No. can only power it on and off...I ordered a broadlink and will try smart ir ...

omersht · 2024-10-02T08:01:08Z

If you have a zigbee network, you can order any super cheap zigbee ir emitter from aliexpress, there are even some battery powered ones, and integrate them locally using zigbee2mqtt, if you do so, i have already learned all rc-3 commands, and set up using json sensor, and climate template for my other electra ac, i can help you set it up.
Also, smartIR dosent work on electra AC’s because of the wired fact that a change temp command doesn’t turn on the AC.

omersht · 2024-10-02T10:53:23Z

I have solved the no temp control issue, add webui, then set temp from webui, then you can delete it, and control temp from home assistant.

mickeyva · 2024-10-02T12:53:24Z

I have solved the no temp control issue, add webui, then set temp from webui, then you can delete it, and control temp from home assistant.

Great. Can you post your ESPHome yaml file and ElectraClimate.h? can you be more detailed about the above procedure?

omersht · 2024-10-05T15:26:50Z

I have Made Some tweaks: 1. fixing the no temp control(hopefully), 2. removeing the non used fan off/on modes,3. add fan auto,4. added swing, 5. changed default max temp to 30C , 6. fixed the off command and 7. added the fan only and dry modes.
At some point custom componenets are supposed to be deprecated, so this shoud be made in to an extarenl component, but this is a project for another day.

Working great! now I don't know what to do with my broadlinks I ordered :)

mickeyva · 2024-10-07T09:53:32Z

Did you personally utilized a temperature sensor?

omersht · 2024-10-07T10:07:10Z

No

omersht · 2024-10-07T10:07:28Z

But it’s possible

omersht · 2024-10-13T09:05:23Z

Can anyone knows how to add the support for the IR receiver, so a change with the regular remote will be reflected in HA?

Yes, in the github repository I have made https://github.com/omersht/ElectraEspHome
