Now i add a new feature: checkboxes for each day of the week where timers are active

But currently i store the selected days only in RTC RAM... (The timers stored as a json file in filesystem)
So next thing is to store the days in filesystem, too.

Very nice work.
Sonoff products seem finally to have come of age. I spent a lot of time on the Sonoff Basic in-line switch. This has gone through three hardware redesigns. Unlike the R1 and R2 units, the new R3 units actually work reliably with decent wireless range. I gather from @kevinkk525 that the S20 is good, too. These things have a lot of potential MicroPython applications and are very hacker-friendly.

v0.9.0 is available
I've refactor the timer schedule. This makes the functionality much more robust and reliable.
From the README:
The Device always tries to turn the power ON/OFF based on the current timer. Even after a power failure. However, this only works correctly if the current time is set correctly by the RTC. The current time is automatically retrieved from the Internet via NTP sync. At boot and also repeated after start. Of course, this can only work if the device is connected to the Internet via WiFi
You can "overwrite" the current timer at any time by pressing the button on the device. This overwrite will stay until the next timer. After a power failure the "overwrite" information is deleted and the timer regulates the power again.
However, it is still the situation that now and then the RAM is not sufficient. But I already have an idea what I can optimize.

Are you already using littlefs? That would free 4kb of RAM

MicroPython v1.12 is expected to be released within a few days and it'll have littlefs built-in...

With v1.12 I will use it.

Now it's possible to dim the power LED:
