this is an implementation of liads ElectraClimate. with receiving capabilities a few tweaks and fixes, and as a external component, since custom components are now being deprecated. to install add to your yaml config:

external_components:
  - source:
      type: git
      url: https://github.com/omersht/ElectraEspHome
      ref: main

this is built over the original IR Climate Remote, with sending liads logic, and the tweaks requierd for an electra AC, so yaml config is the exact same as the IR Climate Remote, just replace the

climate:
  - platform: SOMENAME

with:

climate:
  - platform: electra

note - you can use an external temp sensor

I was able to understand the iFeel funaction, and document it in the code with notes. but it is a supur complicated fuanctiom to make, due to the remote reporting is own temp sensor state. so as of now, iFeel is not supported

additional options:

Electra AC's(airwell) uses the same command for on/off, but some of these devices also supports a dedicated off command, that will turn the AC off if its on, but wont turn it on if its off, but not all Electra AC's respond to this command.

climate:
  - platform: electra
    name: basment ac
    transmitter_id: ir_transmitter
    receiver_id: ir_receiver
    id: someid
    supports_off_command: True #defaults to True

supports_off_command: it is recomended to try it out with true, and only if there is no success change it to False.

if you wish to be able to sync the state of the ac, (change saved state without sending any ir code) using an Home Assistant service call, add this to your yaml;

api:
  actions:
    - action: sync_electra_state
      then:
        - lambda: |-
            id(someid).sync_state();

change the id to the id you set up in the climate declartion(step above). then you can call this in homeassistant with: action: esphome.YourDeviceName_sync_electra_state replace the YourDeviceName with the name definde under:

esphome:
  name: YourDeviceName

to do list:

• create an home assistant blueprint, to enable the use of contact sensors on the ac.
