During the past few days thermostats have been updated to the latest firmware.
The question is, what has changed?
3 years ago, the thermostats icons in the App showed orange when calling for heat or hot water.
For example, when the thermostat is calling for heat, the icon changes to orange, that is correct.
The hot water icon does not anymore, The hot water stays greyed out with the words 'ON', and has not worked for nearly 3 years. I was told by a couple of senior support this would be adjusted in the next firmware update.
