I am wondering if can do the following with SmartThings.
I have a circulation pump for my tankless water heater. It is currently on a manual timer and runs way more than I’d like. I’d prefer to plug it into a z-wave outlet that is turned on less of the current time but will also turn on when the one of the two bathroom fans is turned on. If the pump was in an off-time-period then it would turn on and off with either of the fans. Can this be done at all? (See sample timeline below for clarification.)
Can I use any z-wave switches on the fans and have the hub trigger the pump outlet when a fan is turned on off, or do I need switches with specific features? (I’ve read something about the need to poll some switches because they don’t send a state change message? That seems sub-optimal.)
Thanks for any guidance/recommendations you can provide. Which reminds me, do you have recommendations for which outlet & switches to use for this?
Here is an example timeline:
7:00a pump on due to time
8:00a fan-1 is switched on, no change to pump
8:30a fan-1 off, no change to pump
10:00 pump off due to time
1:00p fan-1 on, pump turned on since not already on/not during on time
1:30p fan-1 off pump turned off
5:00p pump on due to time
7:00p pump off due to time
10:00p fan-1 on, pump on
10:15p fan-2 on, pump stays on
10:20p fan-1 off, pump stays on because fan-2 is on
10:15p fan-2 off, pump off
