FYI, Honeywell Home down? Current problems and outages | Downdetector
“Authentication failed”...
Thanks for confirming ... wanted to be sure it wasn't me as I had shut a breaker off to install more Caseta switches and found that TCC wasn't working.
Back up for me!
Piggy-backing an old thread - anyone TCC users getting "Service Unavailable" today?
I really need to dump this WiFi thermostat, but not in the near-term toys budget.
Seems to be working for me; was able to login just now with no issues.
Down again! On one of the coldest days in two years. What a sorry service.
TCC seems to be going down more and more as well as becoming unresponsive. Considering switching to Zwave thermostat, but would like to find something with a larger color touch screen like the Honeywell Wi-Fi units I have. Any suggestions?
