I think 1.5 to 3.5 is lala land for ttl 5v. As you disconnect components where does it rise? Like the pwm motor controller what are its specs?

I have a recollection of a wifi lig that can be activated. I tried to find that - no luck.

That log, if it exists, might give more clues.

I would measure the voltages being supplied to assure they are not lower when the problem occurs.

If you have a scope look at the pwm pins too.

Where have you searched?

Use a ruler if you want to measure its size. Use google if you want to measure its charge.

I would run nodered on my server. Easy to use.

Or MQTT.

I have used both.

Or a service: many choices available.

Tom

That is my ratio for use.

I view frequently to learn and occasionally to teach.

The posting mostly are very specific about an area and thus few can reply from experience.

Have you tried: wifi_on, false?

Have you looked at the .h .c for wifi
