Hi all, I’m having problems with my Netatmo Thermostat App, it just displays “!” in both images of the thermostat?? I have fully reset the thermostat by holding the bladed button for 20 seconds (slow pulsing blue light, then 5 quick flashes of the blue light) I then reset it up eventually on an android tablet as trying on my iPhone didn’t work (the app appeared to keep crashing) but on the android tablet it did actually complete the installation, the app does display my address and outside temperature correctly, but just not the inside temperature. I have changed the batteries on the thermostat and that works perfectly fine talking to and controlling the relay… any help would be appreciated, these things can’t half be a thief of time…
