Upgraded to yesterday's firmware (20170219) and now the temperature (including the raw %TEMPR%) often reads zero. The temp/humidity sensor I've had for a fortnight or so has previously been reading OK as far as I've noticed (was on 20170131) but is now showing zero. They sometimes show good values but I haven't been watching carefully enough to see a pattern - maybe it's just for a while after they're plugged in but they do fail before the “lila” light goes out. They can also work after that light goes out.

I also haven't tried my CO₂ monitor for long enough to see if that's OK or not.

Sometime tomorrow I'll try going back to the previous firmware (20170131) to see how that works.
Perhaps it just fails when it goes into power safe mode. I've clicked on the Rescan Sensors button but not sure if that's be seen when it comes out of power save or not. Whatever, temperature stays indicating zero.

yeah... i also just noticed this
seems like the SI7021 needs a little time to boot, and since i optimized the start time of the firmware the sensor still reads 0

Here, my temperature reading was fine for a couple of hours, then dropped to 0 (SI7021). After a reboot it's now back to normal; I will report if this happens again.

Upgraded both my temp/humidity sensors this morning. They've both been giving sensible readings for an hour and a half now so definitely looks fixed. Thanks.

Ok, I will update once I have physical access to the device again (probably Thursday) and let you know if the update helps.

btw.. one of the features that i haven't yet described is to define an mqtt topic on which the device will check for retained messages each time it wakes up
so this way if you want to manage it remotely you could potentially send a command to tell it to not go to sleep
and after few minutes when it is up again - connect to it via the config tool Smile

I can confirm this is fixed: after the update I have not seen the temp failure again.

Thanks,
