Why are the thermostats so poorly supported in terms of downloading data?

[GreyArea]

It either never works, or there's just not enough data. It's my house, my device, my data. Why can't I pull down a simple temperature log? Ten days in the nest app isn't enough. Migrating to Google home is a joke...not even an option for it.

Have you tried takeout.google.com ?  You can download all your data from there

See above under "it never works". I just wait 24 hours then get an error message along the lines of "there was an error".

Helpful. Not.

I'm trying it again.

What about setting up a log using ifttt ... It should be able to record readings into a spreadsheet for you 

[GreyArea]

Hmm, I could try that...though of course it means I have to have another device constantly on to hold the log...and also to learn how to get IFTTT to work, which I have spectacularly failed to do on several previous occasions!

[Ashepherdson]

You should be able to link the log to a Google sheets file , no need for a device.  I did it years ago but have not used ifttt for a while.

Ah yes, here, https://ifttt.com/connect/google_nest_thermostat/google_sheets

Failed at first hurdle. Nest can only "IF" on "change" triggers; temperature falls below, rises above, etc. There's no option for a regular hourly reading.

If I use date/time as my trigger, then Google Nest has no "then" options.

Let down on all sides it seems...

[GreyArea · Accepted solution]

Lol...I can set a trigger "if temp falls below "x"...but I can't replace "x" with "current temperature setting" from the device.

This isn't hard you know...we don't want the moon; five pieces of data at best; the timestamp (ideally split into a separate date and time), the target temp, the actual temp and whether the heating or cooling is active.

Fairly basic for a thermostat I think we'd all agree..!

Looks like they changed the ifttt integration .. I'll see what I can find out later today when I have more time.   Just read this guy who did what your looking for https://www.instructables.com/Nest-Thermostat-Data-Logger/
