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. Review: Other Shelly products are great - Not this one though - It appears that this unit won't maintain a stable connection with my network. The temp displays in Celsius.... The time only displays if it's connected to the internet, or synced through the app, not sure. I think the temp. and humidity are inaccurate on mine. Maybe the offset adjustments can fix that, but I didn't get that far to test it. I didn't want to use the Shelly app, but in an attempt to salvage anything good of this unit (and at least give Shelly benefit of the doubt and use this how it's intended to be used), I installed the app and ran into issues. You must have an active internet connection to sync. this device with the Shelly app. You have to create an account too. Being unwilling to connect the app to the internet, I gave up. The goal was to run this through Home Assistant, but it only reports the temp/humidity initially when it first connects and then loses connection. Maybe related to network issue, dunno. Shelly, your other products are good, work over wifi, and don't require internet and an app. What happened to this one? ## Features - Shelly H&T Gen3 Black is a next-generation Wi-Fi and Bluetooth temperature and humidity sensor equipped with the new Shelly chip: 8MB of memory and faster responsiveness.

I spent a lot of time reviewing different devices, interfaces and their specifications. I wrote software to manage this device, including RPC, Bluetooth and MQTT. I am also very experienced in the dynamics of environmental monitoring for residential and commercial buildings. In my opinion this is an excellent humidity and temperature monitor at a low cost for home automation. The interfaces are well documented, easy to work with and there are numerous open-source implementations and libraries available. If you are a non-developer or a home automation user, this device will monitor humidity and temperature and perform well. I have read comments regarding long times to report changes. Temperature and humidity do not change rapidly in normal residential or commercial environments. If you require fast change detection, you are designing for a problem this device is not intended for. This device reports on wakeup every six minutes. The reason is to save battery life. That is sufficient in normal environments. If you require fast response times, select a different type of device that is plugged into a power source and reports continuously. The device will need to support rapid temperature and humidity changes and those types of instruments are much more expensive. The big issue is accuracy when detecting changes. It does no good to use a cheap device that reports every 5 seconds if the changes are only +-20% accurate. Accuracy requires either time or money. ## Frequently Bought Together - Shelly H&T Gen3 Black | Wi-Fi and Bluetooth Smart Temperature & Humidity Sensor with Remote App Control & Monitoring | Smart Scenes | Notification Alerts | LCD Display | Free Data Storage Export - Shelly Plus Plug US | WiFi & Bluetooth Operated Smart Plug with Power Measurement | Home Automation | iOS Android App | Alexa and Google Home Compatible | Monitor Appliances | Remote Control --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/612115774-shelly-h-and-t-gen3-black-smart-wi-fi-bluetooth](https://www.desertcart.us/products/612115774-shelly-h-and-t-gen3-black-smart-wi-fi-bluetooth) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-05*
