Looking for garage heater, US, 240v, 5000w (lemmy.world)

Can anyone help with pointers for automatable garage heaters? So far my searches aren’t finding anything. My requirements are:

  • remotely preheat when I want to work out
  • alert if it’s left on, or automatically turn off

I’m in the US, looking for 240v maybe 5,000w electric heater. The basic item is cheap and readily available at home centers or online. I even see variations with Bluetooth remote and/or controlled by app.

I’m looking for something locally automatable. Matter/Thread would be ideal but I’m fine with Zigbee or z-wave. But I’m not finding anything like that, and getting stuck on some vendors portal is not ok. Any leads?

Or something that can use an external thermostat - I actually have an extra Ecobee - that can be locally automatable. Any leads? Any search tips that might find such a thing?

I briefly thought of automating an outlet, however even if smart outlets are available for those loads, that wouldn’t work because all these heaters have a safety feature to run the fan until the unit is cool

If you can find one with IR remote, you can use something like broadlink rm mini 3 or 4 to learn commands

A second option I can think off is If heater has a button (not touch ones), you could use a fingerbot and add a temp sensor further away on direction of the fan so you can make an automation to ensure it is on or off

The IR blaster is not a bad idea. While I didn’t notice that, I wasn’t looking for it. I do see some with Bluetooth remotes and I imagine there’s similar I could look into
