Its twin radios, Zigbee and Bluetooth 5 LE, let it join a Zigbee coordinator or report to a Shelly gateway, and its 37 mm IP54 shell is rated for a bathroom, a garage or a sheltered balcony, running about three years on one CR2032. The GoveeLife Hygrometer Thermometer H5104 answers with a 3.1 inch LCD showing the reading on the spot, but Bluetooth is its only radio and it carries no weather rating. Pick the Shelly for a multi-room Zigbee home or a damp spot, and the GoveeLife for a cheap screen you check in the room.

What the differences mean

Radios

The Shelly BLU H&T ZB carries Zigbee 802.15.4 and Bluetooth 5 LE, so it can join a Zigbee coordinator directly or broadcast to a Shelly Bluetooth gateway. The GoveeLife Hygrometer Thermometer H5104 is Bluetooth only, with no Zigbee, Wi-Fi or Thread, so its smart home path is narrower.

Weather resistance

Shelly rates the BLU H&T ZB IP54, which covers dust and splashes and makes it suitable for a bathroom or a sheltered patio. The GoveeLife Hygrometer Thermometer H5104 carries no weather rating, so it stays indoors.

Display

The GoveeLife Hygrometer Thermometer H5104 has a 3.1 inch LCD showing the live reading and the min and max values. The Shelly BLU H&T ZB has no screen, just one red LED, so its numbers only exist on a hub, in the app or in a dashboard.

Battery

The Shelly BLU H&T ZB runs on a single CR2032 coin cell rated for around three years, which suits one in every room. The GoveeLife Hygrometer Thermometer H5104 uses two AAA cells and pairs them with an LCD, a different upkeep than a coin cell.

Size and ecosystem

The Shelly BLU H&T ZB is a 37 x 37 x 10 mm, 13 g square, small enough to disappear on a wall. The GoveeLife Hygrometer Thermometer H5104 is a much larger 96 x 72 x 33 mm unit, and it reaches Alexa, Google Home and SmartThings only through a Shelly gateway rather than a voice assistant of its own.

What owners say

Owners of the GoveeLife Hygrometer Thermometer H5104 call it accurate and cheap, with readings that match between units and refresh every couple of seconds, and they like the LCD showing current and min/max values without opening an app. What they really buy it for is the logging: the Govee app keeps customisable graphs with dew point and VPD, fires push alerts when readings cross a threshold and exports up to two years of history, which owners use for greenhouses, aquariums, cellars and even disputes over damp in a rental. Their main frustration is that it is Bluetooth only, so live readings need you within range and anything beyond that needs a Govee hub. A few also note that Govee's own humidifiers are poorly supported in Home Assistant, which limits some automation ideas.

Frequently Asked Questions

Which is better overall: GoveeLife Hygrometer Thermometer H5104 or Shelly BLU H&T ZB?

The Shelly BLU H&T ZB, for most smart homes. It brings two radios, Zigbee and Bluetooth 5 LE, an IP54 shell and around three years on a coin cell, and it works with Home Assistant through Zigbee2MQTT. The GoveeLife Hygrometer Thermometer H5104 is the better pick only when you want a screen on the device and a simple Bluetooth logger.

What is the biggest difference between the GoveeLife Hygrometer Thermometer H5104 and the Shelly BLU H&T ZB?

Reach and ruggedness. The Shelly BLU H&T ZB speaks Zigbee and Bluetooth 5 LE, is IP54 rated and fits a bathroom or garage, while the GoveeLife Hygrometer Thermometer H5104 is Bluetooth only, indoor, and buys its place with a 3.1 inch on-device display.

Does the Shelly BLU H&T ZB need a hub?

In one form or another, yes. Over Zigbee it needs an existing coordinator, and to reach the Shelly app and therefore Alexa, Google Home or SmartThings it needs a Shelly gateway or a Shelly Plus, Pro, Gen3 or Gen4 device on the network.

Does the Shelly BLU H&T ZB work with Home Assistant?

Yes. Zigbee2MQTT supports this exact model, exposing battery, temperature and humidity, so it appears in Home Assistant as soon as it joins the Zigbee network. The GoveeLife Hygrometer Thermometer H5104 also reaches Home Assistant, but over Govee BLE rather than a mesh.

Which one can be used outdoors?

The Shelly BLU H&T ZB, in a sheltered spot. Shelly rates it IP54 and points it at patios and balconies while advising against heavy rain. The GoveeLife Hygrometer Thermometer H5104 has no weather rating and is indoor only.

Who should buy which one?

Buy the Shelly BLU H&T ZB for a Zigbee home, a damp room or a multi-room setup that wants no maintenance. Buy the GoveeLife Hygrometer Thermometer H5104 when the priority is a screen you can read in the room and app-based history.
