I have a central ventilation system that I can control at four levels using three KNX actuators (a, b, c, d), with settings (on, off). The correct combination of these actuators determines the appropriate fan level:
A 0
B 0
C 0
D 0
= Level 2
A 0
B 0
C 0
D 1
= Level 1
…And so on
How can I create a 4-stage slider or fan controller in Home Assistant that sets the correct actuators to the correct positions?
You could use a helper (dropdown or number) and create an automation triggering on state changes. As action use knx.send.
Or maybe find a template entity to do it all in yaml.
