H&T Gen3 Black | Wi-Fi Smart Temperature & Humidity Sensor | Remote Control & Monitoring | Smart Scenes | Notification Alerts | Free Data Storage Export | No Hub Required | Alexa & Google Home

This is part of a range of devices that Shelly sell to control items around the home, as such to get the most out of it you do have to carry out some work yourself. That said, this is a very easy device to set up: insert the batteries, use a mobile phone to connect to the device, set up the wifi and away you go. The display is very clear and easy to read and the device feels good quality. It comes with a simple stand and can also be wall mounted or stuck onto a wall with the supplied pads. You can connect it to other systems and then use the readings to control other devices. Many people seem to connect it to home assistant but it can also connect to other systems with some work. I connect it to a MQTT broker and then use that to connect to Apple home where it displays the temperature and humidity. The device only connects to the Wifi system for a few seconds to update it's values and then goes back to sleep, however as the display is an e-paper display this stays on. The device updates it readings every so often (I think it states every two hours if nothings changes), or whenever they change by a certain amount, thus conserving battery life. Consequently it can be a few tenths of a degree out before it updates. It can also be triggered by a change in humidity which it also displays. I like these devices, they seem to be the best from Shelly and I intend to get several more. Note the Shelly web site states these will be upgraded to matter in the future, and when this happens you should be able to connect to a wider range of systems directly.

I purchased this humidity and temperature controller as I wanted to have a remote control device to alter heater settings when required. When I received it I immediately realised that it was an excellent visual device too, as it uses the same screen technology used on the latest Kindle Scribe, which makes it easy to read the screen in poor light and very strong light, which the cheaper displays do not use and consequently are a pain to physically read. It also operates off batteries or a USB C connection, the latter being best if you are using it tom perform frequent control functions. It was also easy to set up with the Shelly app and gave accurate readings. All in all good value for the money.

Great display A little difficult to set up

Wish i didnt waste so much time on this. The display is faulty out the box- The temp and humidty readings are wildy different on the display vs the shelly app precise check ins. Which in turn makes home assistant get another 3rd diff reading. We should ignore HA as there are other parameters in place. But the devoce itself is unreadable and temp logs vastly diff between devoce display and app, not sure which one to believe. Humidity again is wildly different and more extreme if at all readable. Wish i didnt spend so much tim on it.

Great temperature sensor, nice and clear display and the connectivity is brilliant, the app is easy to setup with the ability to offset the reading and works with home assistant too

I've had these a couple weeks and they're pretty awesome. Using them with home assistant and works well. I put them on a separate VLAN with no internet and they're very happy, none of this internet-required nonsense. They can connect to multiple WiFi networks with customizable signal strength switching, communicate over quite a few protocols (I use MQTT), e-ink display looks good, and you can even use a custom network time server, so even without internet the on-screen clock works as I host one locally. I'm using them with home assistant for automations to control heating in each room based on the temperature. They're a little expensive but I got them on offer for £21 each, I bought 6 and want more. They also come with a nice detachable stand as well as a 3M sticky pad for wall mounting, and just use normal AA batteries or USB-C power.

Bought to use in a shed and send readings to home assistant. Reasonably easy to connect it on WiFi but then the problems start. First I find out it doesn’t like running on batteries, apparently they can heat the device, affecting readings, so it may only report every hour rather than supposedly every 6 mins on external power. No way to change those times. Even on external power it only connects when temp or humidity change (you can reduce the thresholds) but in reality it doesn’t always connect when they change. Activating a websocket on the device seems to improve reporting to home assistant. It still often just stops connecting, it’s on the edge of my WiFi and gives up trying. To get to the button to force it to wake you have to open the back of the device, which isn’t great. I wouldn’t trust it to trigger anything critical in home assistant. Maybe it works better with other Shelly devices. Nice display though.

A bit expensive for what they do but once you have a few of these coupled with home automation the quality is what you'll appreciate - love my Shelly devices

Works great and connected easily to wifi. I wanted to monitor temperature and humidity where connecting to mains power is not an option. Also I wanted to monitor temperature and humidity remotely via wifi. This device fills the bill perfectly. There are a couple of quirks due to the battery power saving design. It only updates when a specific temperature or humidity change is exceeded. You can set the sensitivity to change but setting the limits too tight will affect battery life. Also when you make a setup change or update firmware that will not occur on the device until a transmit cycle is triggered by conditions changing. You can trigger it to transmit by pushing the update button which is accessible after you remove the battery cover.

Top quality product from a top quality company. It works perfectly, the values are quite precise, battery life is acceptable.

preso perchè Shelly è parecchio indicato ed attivo con Home-assistant, infatti è stato riconosciuto subito con dispositivo ed entità. Le batterie non sono presenti (4 AA) così come non è presente un alimentatore e cavo usb-c. Lo sto usando con le batterie, è meno reattivo ma nel complesso non è una tragedia, il check avviene un paio di volte l'ora come minimo. Attenzione perché da qualche parte avevo letto "plus" che indica il fatto di poter fare da gateway ai modelli Blue, questo non è vero nonostante abbia il bluetooth. Probabilmente errore mio, in ogni caso sappiate che non è presente questa funzione. Un po' scomodo il tasto di attivazione del web-server, che permette tra le cose anche di effettuare l'aggiornamento firmware. Questo talvolta va premuto ed è dentro la scocca a pressione. Vero che servirà una volta l'anno, ma potevano farlo meglio. Nel complesso sono soddisfatto, la misurazione per quanto testato è corretta, il display e-ink è bello da vedere e si legge bene.

Keeps temperature and humidity updated in areas where a want temperature and humidity to trigger actions in Home Assistant. Works perfectly fine!
