Its larger 3.6 inch LCD shows the live reading with 24-hour highs and lows, and it carries both Zigbee 3.0 and a Bluetooth Proximity Mode that pairs straight to a phone before any hub exists. The GoveeLife Hygrometer Thermometer H5104 counters with a lower price and a clear 3.1 inch LCD of its own, but it is Bluetooth only and its smart home reach stops at Home Assistant over Govee BLE. Choose the Sonoff for a Zigbee household or a display read across the room, and the GoveeLife for a cheap Bluetooth logger you read and export on your phone.

What the differences mean

Radios and ecosystem

The Sonoff SNZB-02DR2 AirGuard TH runs Zigbee 3.0 alongside Bluetooth, so it joins an existing Zigbee mesh and gains remote access, scenes and alerts through a gateway. The GoveeLife Hygrometer Thermometer H5104 is Bluetooth only, with no Zigbee, Wi-Fi or Thread, so you read it in range or pull its history later.

Smart home support

Once on a Sonoff gateway the SNZB-02DR2 answers Alexa, Google Home and SmartThings voice queries and reaches Apple Home and Matter through Sonoff's own bridges. The GoveeLife H5104 works with the Govee app and Home Assistant over Govee BLE, and nothing else, so there is no Alexa, Google Home, HomeKit, SmartThings or Matter path.

Screen size

Both have a monochrome LCD, but the Sonoff SNZB-02DR2 AirGuard TH is the larger at 3.6 inches against 3.1 inches on the GoveeLife Hygrometer Thermometer H5104, which is the difference between reading it across a room and stepping closer.

Warranty

Sonoff backs the SNZB-02DR2 AirGuard TH with a 2 year warranty, while the GoveeLife Hygrometer Thermometer H5104 carries 1.5 years. Over a cheap sensor the extra months are the only after-sales difference between the two.

Size and mounting

The Sonoff is a slim 18.2 mm slab at 99.3 g that stands on a fold-out foot or hangs from a hole, while the GoveeLife is about 33 mm thick and 108 g. Neither is heavy, but the Sonoff sits flatter against a wall.

What owners say

Owners of both sensors end up praising the same basics: quick setup, readings that match a thermometer they already trusted, and a screen or app that makes the numbers easy to check. Beyond that, Sonoff SNZB-02DR2 AirGuard TH owners single out the big display readable from across a room, the switch to common AAA cells rather than a hard-to-find coin cell, and the ability to show a second Sonoff sensor's reading on the same gateway, while a few note that settings only land after the button on the back is pressed and that the eWeLink app can lag behind the screen. GoveeLife Hygrometer Thermometer H5104 owners talk more about value and data logging, using the app graphs, dew point and VPD and the exportable history for everything from a nursery to a humidity dispute with a landlord, and their complaints centre on Bluetooth-only range and the missing voice-assistant support. Neither group reports trouble with the sensing itself.

Frequently Asked Questions

Which is better overall: GoveeLife Hygrometer Thermometer H5104 or Sonoff SNZB-02DR2 AirGuard TH?

For most people the Sonoff SNZB-02DR2 AirGuard TH. It pairs Zigbee 3.0 with Bluetooth, works with Alexa, Google Home, SmartThings and Home Assistant once on a gateway, has the larger 3.6 inch screen and a 2 year warranty. The GoveeLife Hygrometer Thermometer H5104 is the cheaper Bluetooth-only alternative for a phone readout and Home Assistant over Govee BLE.

What is the biggest difference between the GoveeLife Hygrometer Thermometer H5104 and the Sonoff SNZB-02DR2 AirGuard TH?

Connectivity. The Sonoff SNZB-02DR2 AirGuard TH speaks Zigbee 3.0 for a mesh and remote access plus Bluetooth for local pairing, while the GoveeLife Hygrometer Thermometer H5104 is Bluetooth only. That one difference decides what each sensor can do with your smart home.

Does the Sonoff SNZB-02DR2 AirGuard TH need a hub?

Not to get a reading. In Proximity Mode it pairs to a phone over Bluetooth and shows live values and history. A Zigbee gateway is what adds remote access, scenes, push alerts and the remote sensor display, and an Echo with a built-in Zigbee hub can serve as that gateway.

Does the GoveeLife Hygrometer Thermometer H5104 work with Alexa, Google Home or HomeKit?

No. The GoveeLife Hygrometer Thermometer H5104 is Bluetooth only and works through the Govee app and Home Assistant over Govee BLE. It has no Alexa, Google Home, Apple Home, SmartThings or Matter support.

Which of these is better for Home Assistant?

Both are supported, but differently. The Sonoff SNZB-02DR2 AirGuard TH has a Zigbee2MQTT device page and works on ZHA with a script Sonoff publishes, so it reports through your coordinator. The GoveeLife Hygrometer Thermometer H5104 reaches Home Assistant over Govee BLE, which is a local Bluetooth read rather than a mesh.

Who should buy which one?

Buy the Sonoff SNZB-02DR2 AirGuard TH for a Zigbee home, a wall-readable display or voice queries. Buy the GoveeLife Hygrometer Thermometer H5104 for a low-cost Bluetooth sensor whose app graphs, dew point, VPD and exports are all you need.
