Recommendation for a smart in-wall plug
-
I currently have an HVAC system in the attic - for heating and A/C. 120v is supplied to the unit to run the gas heating. A/C uses 240v. I have an ecobee thermostat...which sometimes goes offline....not often. When it goes offline, I need to turn the 120v power to the HVAC system off and then back on (the ecobee gets its power from the HVAC system). That resets the ecobee and all is fine. I spend the summer away from this house and if the ecobee goes offine..I have no current method to reset the HVAC 120v power remotely. My idea is to replace the current 120v plug in the attic with a smart plug...then I can remotely turn the 120v power off and the ecobee will reset and come back online. I use Wyze and Lutron Casita in the house currently and was hoping I could find an in-wall smart plug from Wyze or Lutron. Obviously, I don't need diming, etc...just the ability to turn the plug power on/off. I've seen some options...but one problem I have is the attic can reach up to 135F in the summer...many of the smart plugs I've seen are not rated for that temperature. Might any of you have any thoughts on a smart plug I might want to look at? I don't want to invest in anything that would require a new hub - so either WiFi based or Casita HUB based. I need 120v and 15amp ratings. Thanks in advance.

It sounds like you've got a solid plan to reset your HVAC system remotely using a smart plug! The high attic temperature is definitely a key concern here. Most consumer-grade smart plugs aren't designed for environments as hot as 135°F, but there are a few industrial-grade or higher temperature-rated options you could consider.
Unfortunately, Wyze and Lutron don't currently offer smart plugs that can handle that kind of heat. However, here are some options that might work for your situation:
Kasa Smart Wi-Fi Plug by TP-Link – This plug is reliable and WiFi-based, but it’s only rated for temperatures up to around 104°F. You could possibly mitigate the heat with some insulation or a vented enclosure.
Insteon On/Off Outlet – While this requires the Insteon hub, it’s designed to withstand higher temperatures, and it's one of the more durable options available.
Meross Smart Plug – Meross plugs are Wi-Fi based and may be more temperature-resistant compared to regular smart plugs. However, you'd need to check specific temperature limits.
If none of these options work in the attic due to heat, you could consider placing the smart plug in a cooler area outside the attic, connected to a switch that controls the HVAC unit.
Lastly, make sure the plug you choose can handle 15 amps and ensure that the installation adheres to local electrical codes for safety.

It’s a smart idea to use a smart plug to reset your Ecobee remotely. However, the high temperatures in the attic (up to 135°F) are definitely a concern since many smart plugs aren’t rated for that heat. Unfortunately, Wyze and Lutron Caseta don’t offer in-wall smart plugs that are rated for those temps. You might want to look into industrial-grade smart plugs that can handle extreme conditions, or maybe relocate the smart plug to a cooler spot near the attic access, if possible. Kasa makes some Wi-Fi-based options rated up to 104°F, but you'd need to confirm if they can handle brief periods of higher heat. Be sure to double-check the specs to ensure safety and longevity.
