I don't think CR2077 is a size, it may be a typo for CR2477 which is very common?
CR2477 is high enough capacity that it's used in a number of zigbee or zwave800 based products that have no wired interface.

It is indeed a typo! Thanks.
Interestingly I’ve used Zigbee for well over a decade, tried easily over a hundred different devices, built others homes, and I’d never encountered this battery size until this project!
Will fix the typo later
