I want to be able to remotely turn on my water heater (wall hung boiler) and well p7mp using the m1. What would I need to use to control these.
I am also interested in upgrading to the Ethernet/cell dealer. Would it be feasible to control smart devices with google home or Alexa with that device? I could conceivable at smart switches/outlets to control the other devices. How do I know which the best cell signal to use would be? ATT vs Verizon?
Are these devices 220 VAC and less than 30 Amps? If so you may want to consider using the ELK 9200 Heavy Duty Contractor https://www.elkproducts.com/product/heavy-duty-relay-contactor-9200/ to control these devices. The ELK 9200 operates on 120 VAC but can switch up to 220 VAC @30 Amps using an Appliance Module or any other means to switch the 120 VAC.
I use an ELK-9200 Heavy Duty Relay/Contactor to shut off power to my well pump whenever a water leak is detected. It should work well for your application.
Even with my water pump turned off, my well expansion tank will continue to supply water to my house until the internal bladder pressure reaches zero. This article describes using a ELK-WSV2 to immediately shut off the flow of water (as opposed to just turning off the well pump): https://www.elkproducts.com/dont-get-washed-away-by-water-leaks/
