The previous version of the Netatmo Thermostat (with no HomeKit logo displayed on the packaging) will be upgraded in the next coming months to be HomeKit compatible.
I couldn't find any info on an upgrade in this topic. I ordered my thermostat on an online sale yesterday, and it's on it way now. I hope this will be the one with the white LED, but since it was 118 euro's (about $ 99) I'm afraid it could be a clearance of older units
Does anyone have up-to-date info on a possible upgrade plan for older units?
