Hello @Sir_Goodenough,
I totally agree with Enrique and I truly believe that HA should consider adding the Local Control to the current IntesisHome Integration that works through Intesis’ cloud. I am afraid but it is not reliable at all as it gets disconnected very often.
The local control works like a charm and as Enrique has mentioned, I also believe that the HA Team should look at the Custom Integration (GitHub - jnimmo/hass-intesishome: Experimental fork of the IntesisHome integration for Home Assistant) and natively add the extra functionalities that the custom one has.
Until I have found the Custom one, I have not been able to rely on the HA to turn On/Off or Automate my AC.
