One more brief update about our Nest thermostats. After a few weeks of limited use of our HVAC system due to a very unusually warm late winter and early spring, I’d set the whole house to AWAY mode last evening. However, a bit later, I heard the furnace running. Odd. I walked to the thermostat that I’d set to away and confirmed it was still “AWAY.”

imageI grabbed the iPad and used the Nest app. The thermostat that I had set AWAY to was reporting the same error that I’d seen back in January: the giant question mark. Tapping the image resulted in the message:

Thermostat Disconnected – The thermostat First Floor last connected to the nest.com more than 3 days ago.

Three days?

So, I went to the thermostat and checked it’s settings. Great, no wifi and no account information. It had apparently forgotten it’s wifi connection information completely and also my account information.

Seriously, I’d want to fire myself if I wrote code that was this bad. Why would it EVER dump that information? It’s literally its key to being a smart thermostat.

Thankfully, as we still have 2 other thermostats in the house, it was simple to add the account back to the thermostat after entering the wifi password again, as the thermostat recognized that there were other Nests nearby.

Without the wifi connection, you still have a thermostat (thankfully!). However, you loose all remote scheduling capabilities via their web site or apps.

I still can’t recommend these thermostats. While the “BETA” label has been finally removed from their remote access web application, the device itself still has numerous unresolved issues.
