Thats really interesting result.
If we can keep the xenon up and cloud connected then It will save the need to have an RTC and a more complex application firmware.
At the moment I’m having all sort of reliability with reconnecting devices that where sleeping back to the cloud. Seems Mesh is not ready for mainstream production without the need to kick the entire network to get a few reconnected.
We have a lot of daylight here in NZ, but also some long spans of overcast or dark days, maybe over a week, be interesting to see what the shading does to a device over this overcast period.
