Low temperature warning

[rikardkjell]

"Unit is offline due to extreme temperatures"... -2°C don't seam like too extreme to me but what do I know. It's a wired Nest Hello (gen1) doorbell and this warning and other stuff I really don't like have been pushed on to me due to inability to revert the migration from Nest (here it all behaved) to Home App (here it all turned south)

Hi Rikardkjell,

The “Unit is offline due to extreme temperatures” warning can sometimes trigger even at temperatures that don’t seem extreme, especially with older devices like the Nest Hello (Gen 1). The system may be using conservative thresholds to protect the hardware.

Unfortunately, once the migration to the Home App is complete, some settings and behaviors from the old Nest app—like how warnings are triggered—cannot be reverted. You can try:

1. Check wiring and power supply – make sure the doorbell is getting stable voltage; low voltage can trigger offline warnings.

2. Firmware updates – ensure your doorbell firmware is up to date.

3. Placement – if exposed to wind or direct cold, the sensor may read lower temperatures than ambient.

If the issue persists, contacting Google Support may help clarify why the offline warning triggers at -2°C.

I don't think we're going to "transfer" our 1st gen Google Nest Hello Doorbells from the Google Nest app to the Google Home app.  Besides the missing Nest app functions, and the fact that some customers are reporting that their 1st gen doorbells and cameras go offline in the Google Home app, there is now this.  The stated operating temperature for the Nest Hello is 4° to 104°F (-20° to 40°C), so there does not seem to be any reason to get an extreme temperature warning at -2 degrees Celsius.  We have three Nest Hellos--the oldest for 6 years now, and none have ever gone offline due to temperature extremes in Minnesota winters (down to -20 degrees or lower Fahrenheit) or summers (up to 100+ degrees Fahrenheit) using the Google Nest app.

Incidentally, there is nothing we as customers can do to ensure that our doorbell's firmware is up-to-date; that is entirely under Google Nest's control.

No. Don't migrate (transfer) is my recomendation.
