I’m looking for the best solution to control ball valve.
Valve has 3 wires so I need controller that can control two switches and these switches will always work in opposite states i.e
switch is ON
switch is OFF
when I change state of 1. switch then 2.swich will also change state:
switch is ON->OFF
switch is OFF->ON
The best solution would be something with Zwave. I found .ie TZ78 but I’m wondering if something from ie fibaro can be used.
I use one of these to control the dimmers in my sun tunnels; same principle, switching the live to the appropriate wire moves the shutter in that direction.
