Shelly Temp. Sensor DS18B20 1m cable

The 1-meter cable length is perfect for reaching across my greenhouse shelf without any slack issues, and the DS18B20 chip reads within half a degree of my reference thermometer. Wire detection was instant and the readings have been rock solid over the past week.

Took me five minutes to wire this into the AddOn port, and the readings are spot-on within half a degree of my old thermometer. That 1m cable gives just enough slack to tuck it behind the fridge without stretching.

The 1m cable length was perfect for reaching my HVAC duct from the AddOn, and the DS18B20 readings have been spot-on compared to my handheld thermometer. Setup was genuinely plug-and-play once I found the right terminal.
