SONOFF SNZB-02LD IP65 Zigbee LCD Smart Thermometer (Probe Version)

Have worked flawlessly

I love the look and the temperature is accurate. The range is poor I loose connection all the time and it to less than thirty feet. I am going to install a light switch in between to see if a mesh network would solve this issue.

Using it in my aquarium wiith a Smartthings V3 zigbee hub. Working well as a temp indicator and alarm.

Our house has a pair of water tanks that can be heated either with a water coil fed from our gas boiler, by an electric heater element. The electric element has its own thermostat but the heating coil needs a separate thermometer. I have used these units to replace part of an owl-intuition system to monitor tank water temperature (x2) for display and control of the heating coil. They have proven easy to install, setup and are working well.

I bought two of these to monitor my freezer and refrigerator to make sure that the food in them stays at the correct temperature. After a previous incident that involved frosted evaporator fins, a -30°F freezer, a 50°F refrigerator, and food-borne illness, I'm hyper vigilant when it comes to food temperature. These thermometers give me peace of mind by providing an external display and integration into Home Assistant so I can get alerts when anything is out of whack.

Setting them up with Zigbee2MQTT was very simple, and I haven't seen any reporting delays or any other issues.

My only criticism is that I'd prefer the probe wires to be a bit thinner or even flat, but I was able to modify the seals on my refrigerator and freezer to accommodate the wires without sealing issues.

Excellent! I use one in the sauna because it's one of the few that works at 100°C (the display is outside the sauna room, with the sensor going through the wall). I use the other one outside for my child’s paddling pool water. I connect them via Zigbee to my Home Assistant. The sensor is very accurate — I even measured my body temperature under the tongue with it, and it was spot on 😀

Very good for what I need. I use it to check the temperature in my Aquarium with alert that tells me if the temperature is too high and I use also for an old fridge to check the temperature. The only "defect" I find on this product is that the probe is not replaceable; it should be better have it with a 3.5 jack.

The sensors work quite well. They respond fast and I've never had an issue with them dropping off from home assistant (Z2M). I really like that the main module and screen stays outside of the fridge and freezer (my use case) - that definitely helps signal vs inside the fridge.

My one gripe is that the cables to the probe as non replaceable and round. If they fray, the whole device is e-waste without some hard work probably. I also don't like that the cables are round rather than flat. A flat cable would be more compatible with the door seals of fridges, freezers, and ovens to avoid the leakage of heat/cold.

That being said, I don't think the round one makes a huge difference but it's hard to tell.
