Does anyone know the size of the little screws at the bottom of the Smart Thermostats? I've lost one.

    Hi, the screw used on the earlier version of the Smart Thermostat is a M2.5 x 4mm countersunk machine screw with a slotted head. This is a Metric screw 2.5mm in diameter x 4mm long. I would not recommend anything longer than 4mm as there maybe a clearance problem.

    These can be found on eBay or equivalent, and I recommend to use a Posi or Phillips head as these are easier to start than a slotted head.
