I am looking to control 3 minisplit aircons for a short term rental house. The main idea is to have a motion sensor that will turn the thing off during the day in case people forget to torn them off.
So far I have thought of two things:
- buy 3 Remotec ZXT-600 Z-Wave Plus which will set me back over $220.
-Or get a multi relay for $32.
First option is ideal, but expensive. The second one would work, but super unintuitive and will have to add work arounds for it to come back quick. Also, the a/cs remember their last state, so they will turn themselves back on when pawer is back,
Is there any other product out there I can use to get this done?
