I've got a manual humidistat that has percentage humidity and has low voltage power when the hvac is running.
I'm thinking of using this Remotec Zwave Fixture Switch Module so that I can automate based on current humidity and outside temperature.
New to this so wondering your thoughts on this approach. I will have to run 120 power to it, but that is not a problem for the location I'm looking at, and this will still provide the low voltage switching required to go to my hvac humidifier. I think. Thoughts?
