Almost any of the bigger (5kW-10kW) electric garage heaters can be converted to an external smart thermostat using an Aube relay: https://www.amazon.com/Aube-RC840T-240-Switching-Electric-Transformer/dp/B0037MXM1C?tag=atomicindus08-20 For a temp/cheap setup, a few space heaters on separate...

Bit more $, but here's a similar "saddle" style that is also an inverter: https://www.amazon.com/dp/B0BVGJ1Q4G?tag=atomicindus08-20

Most of the smart thermostats will tell you total runtime. It would be easy to figure out % of total by taking runtime x ratings on the unit and subtract from your monthly bill. When I installed my first Nest thermostat (when they first launched and you had to pre-order it), there were big...

Are you sure it doesn't have programming? I don't use the 2 wire communication setup on my Vision Pro, but it is REDLink compatible. After I added the gateway device (plugs into your router via Ethernet), I was able to setup the wake up/day/return/sleep schedules in the app...

Is there a "G" terminal on the control board? If so, did someone put a jumper on it?

Model# of each component? I'm sure thermostat wiring is buried in the installation manuals.

Here is a SPDT relay I have used in the past for 120VAC circuits: https://www.amazon.com/American-Zettler-Power-120VAC-AZ2280-1C-120A/dp/B07587NZTC?tag=atomicindus08-20

What’s the harm if there is no delay? Is the 12VDC pump also on a float switch?

Between the flashy website with very little technical depth and the fact that they appear to be relying on "someone else" to pay for the device, it all seems very scammy. I don't doubt that the device and the connected app can and will track voltage over time, and that has some very real...

Seems like an easy way to check if the thermostat wiring is suspicious or not is to take it out of the circuit. Mount the thermostat at the air handler and connect with a short piece of new wire. If problems still crop up, it's not the wire running through the wall.

I tried a small number of those bulbs in my previous microwave. First problem is that they are not dimmer rated, so it was a strobe light show whenever the dim setting was used. Second problem is that they just did not last long. I thought I could get ahead by finding dimmer rated bulbs on...

Is this it? https://www.amazon.com/IP-Auto-Alarm-Dialer-Router/dp/B00WF9Q6PW?tag=atomicindus08-20 Looks like it sits there until the alarm siren output turns on.

I had my Trane HVAC system replaced spring of 2019, and I kept the old blower fan to make a nice and big garage fan. So I put the blower/motor on the shelf and kept moving it around for years, until last summer when I sold it on a garage sale for $10. May had been $5. I don't remember exactly...

Is the attic system A/C only? Or A/C and heat? How many wires are on each thermostat? Yes, you can combine thermostats, but you'll need a thermostat that has a separate Rc and Rh.

Like everything else on my to-do list, this one bumped down in priority. I’ve been getting by with 3kW of floor heating. Even on days where the temps never got above zero F, I was able to maintain temp. I guess this is what they mean when they say a properly designed system should keep temp...

Anything WiFi is going to need a constant source of power (C or common wire on the thermostat must be connected). The "learning" thermostats (EcoBee, Nest Learning) have a rechargeable lithium battery. I'm sure they will alert when the battery goes low, but that should only happen when the air...

I’m thinking roughly the same idea for my house. Not for solar and energy offset, but more for having a big backup battery. The EG4 6000XP has caught my eye. https://signaturesolar.com/eg4-6000xp-off-grid-inverter-split-phase/

You might be able to change the panel you have to one with a main breaker. I assume there are no other spaces in the panel below the meter?

All that panel space and it uses double pole twin breakers? I agree with the suggestion of 35Ford to change the panel to a main breaker panel and install a gen interlock kit. As to fuel usage - if you don't use all that much power, it might be worth it to consider both a small backup gen and...

Are you thinking inside or outside? If you put it inside, you really need to keep the area around it clear for access. Sure would come in handy to run additional circuits for anything along that wall, though. Outside you might be able to skip the disconnects altogether if the panel is line...
