Customer Ratings & Reviews

It was not possible to connect to my wifi network using the instructions provided (using the device's wifi hotspot); possibly this was because my phone detected "no internet" and kept aggressively trying to reconnect to the internet. But once finally connected (using the app) it has been great.

It's only been a few days, but so far so good

These are awesome! They last a long time on 4 AA batteries. Using mine with Home assistant, they only send an update once an hour or so, unless nothing has changed.

Worked great.100%. Always reconnected to modem when power went out. Always sent data and warned when something was not right. Best sensor - the others I tried were junk in compoarison.

Works great. Planning on using it as a virtual thermostat.

Love the units unfortunately one of them does not consistently hold temperature even with offsets

Love this device! Have a crawlspace which is lined with plastic, this lets me keep tabs on whether the dehumidifier there is doing its job!

the display is clear and sharp very easy to read. super easy to adopt into the Shelly app and Home Assistant.

easy connection, works great

Looks nice - really like the display. I wish it would wake up for a reading more often - say every 30 seconds, which half the current time. On thing that got me is the button on the thermostat page. It looks like a regular power button with a red underscore. This button turns the H&T off and on. It took me a week to figure that out. (I initially thought that button might override the setpoint and be a manual way to turn on the furnace - but no, it turns off the H&T and no signal goes to the furnace when that button is off. The relay I have on my furnace wouldn't turn on from the H&T. I've ended up owning three of these so yes I like it a lot.

Nice little project

Known quality. I want to add one more heater for this winter and need to control it.

'+ Easily readable screen, accurate measurements - A lot of batteries, not so easy to integrate in Shelly Smart Connect'

Good

Works Great! The physical button should be on the external case, and I wish it had better integration with Alexa, there are no events available to use with this sensor.

Everything was OK!

Well built and easy to setup. Battery last longer than expected. I would only make it easier to stand alone.

Perfect device for keeping track of enviromental issues in various situations.

The Shelly H&T gen3 is compact, clear and easy to read. Setting up was easy with the Shelly app. It works with Google home seamlessly so I can change temperature by voice or on my phone ifI should need to. Mostly it will just keep a constant temperature. The best thing for me is seeing the temperature history including boiler on and off times soI can adjust the water temperature.

Great design, especially with the E-paper display and the possibility to connect it to a USB charger instead of using batteries. I can not judge how accurate it is. However the deviation to a cheap humidity sensor that I bought, is maximum 1%. I think this is good enough. I have integrated it into Home Assistant and it works great. I do not understand why the button for activating it is not reachable from the outside, this would be very helpful, even if you do not really need it, after it is connected to your network and the cloud. A connection by Bluetooth could spare an IP-address in the local network. Other than that, a great device.
