Release 3.4.2 is broken
The code changes in the 3.4.2 release seriously broke the phase & deCONZ daylight sensors. Depending on the configured location and time of year, they could cause bursts of state changes, resulting in a seriously negative impact on system performance. Unfortunately, I didn't take all the boundary conditions properly into consideration, my own testing was minimal, and I did not receive any beta testing feedback.
This release reverts the code changes from the 3.4.2 release. I apologize for any inconvenience.
