Hi,
Wondering if anyone knows for sure if the Wemos mini D1 has problems with pin assignments or other hardware issues in 8266basic.
I am getting strange results, where an esp board works fine.
The basic interpreter is running okay, just wont do a dht22 on pin 4 for instance, where the parts are known to be good.
Thanks
Paul
**edit** I was using the wrong pin numbers.
on a d1 mini, pin4 is gpio2 and pin3 is gpio0 etc.
It works great once I fixed that.
This is Rotohammers thermostat code adapted for a wemos d1 mini and a dht22.
