Shelly Capteur de température DS18B20 Jack 3.5 mm

The DS18B20 chip reads room temp within a degree of my old thermometer, and the 3.5mm plug clicked into my hub with zero fiddling. Wired it up in under two minutes, and it’s been stable all week.

The 3.5mm jack makes hooking this up to my existing setup absolutely effortless. I've got it dangling right next to a vent and the readings are spot-on to the degree every time.

Was a bit skeptical about the jack connection at first, but it clicked in firmly and the sensor read the room temp within seconds of pairing. The DS18B20 chip seems accurate — it matches my other thermometer to within half a degree. Nice and compact too, doesn’t stick out awkwardly from the device.
