Shelly H&T Gen3

Very cool

Just what I wanted, a battery powered temperature sensor that I can put anywhere, links to my WiFi and Home Assistant.

And it is so easy to set up

Associé à la gestion de contrôle de mes volets roulants, il me permet de s'intégrer à des scènes en informant des conditions de températures extérieures. Il s'intègre parfaitement à la gestion thermique de la maison.

The device looks so nice and well finished. I absolutely love the display. And about the software ... As soon as I put the battery in it, the app instantly recognized it, no annoying bluetooth device search forever, it just worked. The spec sheet says the battery can last about a year but it's already down 14% in 3 weeks, so ... I might have to use an USB-C power supply or rechargeable batteries. Also, altough it comes with a double sided tape thingy, it would have been great to have a hole in order to hand it on the wall. Maybe making sure the hole is perfectly centered to avoid the device being tilted was a no go.

Hallo, leider ist h&t defekt. Das Display ist wie eingefroren, selbst ohne Strom oder Batterie.
Was mache ich jetzt?
Gruß, Jörg

man kann nach ein paar Tagen das Display nicht mehr lesen
Die Zahlen werden nicht mehr angezeigt
An wen kann ich mich weden ?
Kann ich den defekten Teil retournieren ?
Kann auch Bild senden

they all work great except one the display is 1/2 on 1/2 off.

The behaviour of the shelly H&T is ok when it's connected to the mains power source, but unfortunately it's different when the equipement is powered with battery. The data refresh rate is then significantly slower.

Funktioniert gut, wenn aber bei 2Geräten dieselben Pixelfehler auftreten, gehe ich von Schlechter Qualität aus.

Ausserdem ist überall ausreichend WLAN oder BLE Abdeckung was eigentlich zu keinen Verbindungsproblemen führen sollte.

Easy to configurate temperature sensor with a good sensibility and accurance. A good tool for smart home and other tasks

Petit thermomètre et hygromètre très facile à intégrer dans Home Assistant

Funktioniert einwandfrei! Lediglich etwas klobig.

Nice room thermostat with limited compatibility. I use three of these – one in each of my rooms – to provide external temperature data for my TRVs. The only issue: these cannot be configured as external sensors for the Shelly Blu TRV. With some workaround, I can send the data to the valves, however, it would be nicer, if this could be set-up via the UI.

Sehr kompakt und macht, was es soll

Satisfied with the product. It looks nice and is made of high quality. The screen is very readable.

Good stuff!

Der erste Shelly ist super der Zweite hat Probleme mit der Anzeige

Super appareil, le design c’est cool. L’écran encre liquide est vraiment beau, bonne lisibilité et précision des valeurs.

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

It is a perfect sensor working fine. The handling works great and great functions. The only thing is, it needs a bit to much energy.

Gutes Produkt nur ist es nicht so einfach das Gerät in die App einzubauen. Etwas technischen Sachverstand solle man haben.

Buono

Kostengünsig und kann für Szenen genutzt werden

I bought 3 Shelly AZ H&T sensors to monitor temperature and humidity indoors (they are not designed for outdoor use). At first everything worked well: quick setup through the app, stable Wi-Fi connection, reliable readings and easy-to-browse data history. The display is clear and the multilingual instruction leaflet is simple but complete. Battery life (4 AA, not included) is fair and depends heavily on the distance between the sensor and the nearest Wi-Fi router or access point.
The problem. After a firmware update, all three sensors stopped working properly at the same time: they went offline and the displays started showing random, overlapping and unreadable symbols and numbers. Without a working display it is hard to even tell what state the device is in during a reset. With a lot of patience, using my phone's Bluetooth as the only confirmation that the sensors were awake, I managed to reset them and reconnect them to the network, but the displays remained unusable.
Customer support. I opened a ticket with Shelly. They asked for photos, videos and the invoice, a reasonable request to verify the defect. After a small initial misunderstanding, corrected within a few hours as soon as I pointed it out, they granted a free replacement of all three sensors, shipping included. Quick replies, courteous tone and no arguing about responsibility.
Why 4 stars and not 5. An update that disables three devices at once should never reach customers, and the reset procedure without a readable display is far from intuitive. I recommend not rushing to install every new firmware on battery-powered devices. In my opinion, it is also wise to run updates with the sensor connected to a phone charger (5 V, 500 mA) through its USB-C port.
In short. A solid sensor with good value for money and well-designed smart home integration. The fault did happen, but the way Shelly handled it gives me confidence in the brand: I would buy them again.
Update: the three replacement sensors have arrived and work flawlessly. Not a single missed reading so far.
