Home automation is the residential extension of building automation.

It is automation of the home, housework or household activity.

Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

Need something along the lines of a Shelly 1 Plus that can be in 140F temperatures (alien.top)

Title says it all. Shelly devices are only rated up to 105F, and I need to control an outlet in my attic (it powers a hot water recirculation pump). It needs to work with an inductive load since it's powering a motor.

Any suggestions? It can be Z-Wave, Zigbee, or WiFi. Will tie back to Home Assistant.

Do you need to place it in the attic? Where's the breaker box that powers the outlet? I ask because I have a zigbee relay controlling the outlet for my washing machine, and another controlling the outlet for my garage heater, but neither are anywhere near what they control. I stuck them in junction boxes closer to the breakers in the basement.

Unfortunately, yes. There are several critical loads on that circuit.

I recommend running a new cable into the attic, with the Zigbee/WiFi relay device in the utility room, garage, or basement, wired in parallel to a manual override switch.

Another option is to disable the recirculation pump in the attic, and install another one (or the same one relocated) where it is more accessible. I have a Grundfos pump next to the hot water heater in the garage, and the pump is plugged into a battery-backed timer.
