.... I just not sure if a tiny MC is better than simple 8dip comparator config.
..
What would you choose for logic?
Do both designs in parallel ?
If you can manage it with simpler logic, that will be lower power and more stable.
There are simple low power timers that can give you some delay or ON time limits.
Once the parts count goes above some limit, you can look to flip to a small MCU.
Something with few pins that can run a 32kHz xtal could give you more options ?
If this is always mains connected (likely dropper powered?) you could also count mains cycles for timing.
What power is available ?
