How to restart and partially reset the Amazon Smart Thermostat

Before attempting any other troubleshooting methods, you’ll first want to try and restart your unresponsive Amazon Smart Thermostat. To do this, simply remove the faceplate from the wall, wait several seconds, then place it back on the wall. If you’re lucky, this will get your thermostat working like new. If that doesn’t work, try performing a partial reset by following these steps:

Step 1: Press the Up Temperature and Mode keys simultaneously for 10 seconds.

Step 2: Wait for the rEs notification to appear on the smart thermostat display.

Step 3: Hold the Mode button for five more seconds.

Step 4: This will reset the device and should fix any lingering issues.

Amazon Smart Thermostat unresponsive troubleshooting

If restarting and partially resetting your Amazon Smart Thermostat didn’t work, there are a few other things you can try. These are largely dependent on what exactly is wrong with your thermostat and only work for very specific issues.

A common issue with the Amazon Smart Thermostat is that the display will go blank. This can happen when the unit is left idle and inactive, and simply touching the screen should turn it back on. If it doesn’t, you’ll need to dive into your Alexa app, locate the Smart Thermostat, and increase your display brightness.

Another common issue that will cause your Amazon Smart Thermostat to behave erratically is if it’s installed in an awkward location. Amazon recommends installing it far away from air vents, sunlight, or other places that produce heat or cold air – such as a portable heater, air purifier, or near the kitchen. Consider moving your thermostat's location if you notice temperature readings that wildly fluctuate throughout the day.

The last way to fix an unresponsive Amazon Smart Thermostat is to double-check your wiring. This is particularly important if you had to install the C-wire adapter, as that requires additional wiring that may be best handled by a professional.

If none of these suggestions work, it might be time to contact an HVAC service to inspect your furnace and air conditioner. Most of the time a simple reset is all it takes to fix an unresponsive Amazon Smart Thermostat, but sometimes your issues might be caused by a more serious problem.

I tried to parody the most absurd AI products, but the tech industry beat me to it
The joke was supposed to be that every household object gets cameras, AI insights, and a premium tier. Apparently, that’s now a business plan
Imaginary AI products

I wanted to invent an AI product so silly that no founder could turn it into a seed round.

It had to solve a problem nobody had, collect far more data than the problem deserved, and turn normal behavior into an insight that sounded vaguely disappointed in its owner. Somewhere around the third feature, it would ask for a subscription.

Fraimic’s E Ink art frame generates art from your voice and looks incredible doing it
Fraimic's AI art canvas is one of the most thoughtfully designed smart frames I've come across.
Indoors, Interior Design, Person

We’ve seen a lot of "smart art frames" at CES over the years. Most of them feel like glorified digital photo frames in turtlenecks. However, there’s one that feels genuinely different: Fraimic, and I say that as someone deeply skeptical of this category.

The pitch appears quite compelling at first. Speak a prompt into the device, and its built-in mic sends the command to OpenAI's GPT Image 2.0, which then generates full-color artwork that lands on a Spectra 6 E Ink display.
