The shorter cable version was perfect for tucking behind my desk setup, and it paired seamlessly with the controller in under a minute. Readings have been spot-on accurate every time I've checked them against my other thermometer.

The two-meter cable option made placement a breeze, and the readings on my dashboard match my standalone thermometer within half a degree. Solid little accessory for anyone already running Shelly gear.

Wired it up in about ten minutes and the readings are spot-on against my reference thermometer. The waterproof probe tip feels sturdy enough for outdoor use, and the extra cable length made routing it through the wall a breeze.
