Correct. My integration is for the Infinitive software. Infinitive acts kind of like another thermostat on the A/C bus. You’d use it if you have the normal “dumb” thermostat.
@MizterB has the Infinitude integration that you’ll need to use if you have the Infinity Touch thermostat.
Either of the integrations should be able to control at least the basic functionality of the A/C unit.
