Update on loop timer stability... I ran for about a month without any problems with the loop timer (5.5 on, 10.5 off), but yesterday I noticed the lights didn't turn off and the sonoffs had lost connection to wifi (my router does seem to be having issues lately - may be the root cause)... Anyway, I cycled the router and the sonoffs, and then turned off the lights. I made sure the loop timer was still set to enable, however, the lights never came back on... That might be a feature (since I manually turned them off), or, it may be a bug that it's not smart enough to figure out the time schedule once it's interrupted.
