Sharing what I did with my hot water recirculator. This will work with just about any pump.
This is what I did to turn my hot water recirculator on for a designated period. I created an Amazon Alexa routine (listed below) which I called Hot Water. When I say “Alexa, Hot Water” it runs the routine.
- Say “Turning on the pump”
- Pump – power on
- Wait 5 minutes
- Say “Turning the pump off”
- Pump – power off
You can also schedule the routine to run at a specific time (e.g. right before you get up in the morning). I prefer to simply tell Alexa when I want hot water and our schedule is not always consistent. I think this also can be done with a google home routine by saying/adding something like “turn on the pump for five minutes” but not entirely sure as I don’t use google home as my main smarthome portal.
Also, if the recirculating pump is in a unconditioned area (garage, attic, etc), I would recommend using the outdoor plug as the specs for the temperature range are broader than the indoor plugs.
