By way of the FCC, we learn something that looks like a third generation Nest Theromostat is en route… with 5GHz joining the party. Now I can’t say for certain the unnamed Nest device is another learning thermostat. But the round profile, withon back, identified as model ZQAT30 (versus the 2nd gen’s ZQAT20) sure seems suggestive.
As the test firm received their sample back in April, but there was no mention of a thermostat refresh at Nest’s June press event, I’ll go ahead and assume some production or engineering kinks have delayed an announcement. As to additional features, beyond new wireless capabilities, no remote sensors have popped (unless that’s what this is)… which has become something of a shortcoming compared to the highly regarded (and now HomeKit-compatible) ecobee t-stat.
