After a lot of tinkering I’ve finally figures out how to setup and implement (and use) the Time Input Widgets. As this was certainly not trivial I decided to share my findings in a generalised piece of code.
I’ve started out with @Costas ezischeduler (check out that post to see the app side of the implementation) and had some exchange of thoughts with @Gunner.
The biggest difference in regard to other posts with examples (which used weekdays) that I’ve found on this forum is that I’ve split up the ‘schedule update’ and the ‘schedule check’ routines, which (in all examples) were both handled by the blynk_write() routine. The other change is the easy setup of multiple timers. Below the result
DISCLAIMER: I’ve extracted this from my current project and changed it so its more ‘general’ but I haven’t tested it. So should you find something, please let me know and I’ll update this post. It does compile and its derived from code that is tested (and works).

MultiScheduler.ino by Wolph42, 6 6 2018
Example use of the Timer Input Widget to schedule tasks
Based on Costas EziScheduler.ino
This code allows you to create upto [number of available virtual pins] timers.
Stuff you can/should change (besides the usual auth/ssid/pass)
- "MAX_SCHEDULE": sets the number of available timers (currently set to 2)
- "START_TIMER_PIN": this is the FIRST vpin used for the widget input timers (the
second vpin in use will be START_TIMER_PIN + 1 (e.g. V10, V11, V12, etc.).
Note: in case you didn't know 'V10' == '10'.
- "//PUT YOUR START/STOP ACTIVITY CODE HERE!!": I guess this speaks for itself.
I've added OTA as well as this makes life sooo much easier! But you can remove
those lines is not needed.
