I tried combining my e-switch version with my NOINIT (power switch) in order to get full functionality on both switch's, but ran out of code space. I just ordered a few ATTiny45's - they have 4 * code and data space. There's been some successful porting effort goin on, so hoping I can get these up and running.
Update: Mission Accomplished! Got it working now on a ATtiny45. Some details here: https://budgetlightforum.com/t/-/34900, post #115.
