16X2 LCD screen

Hi,
I'm using a 16X2 LCD matrix using I2C- for a project using RPI_ZERO_W.
I'm looking for a equivalent lib in microPython for ESP32/ ESP8266.

Re: Last will on umqtt.simple

So this is a totally different problem now than what you started the thread with? I.e. your client keeps losing the connection? Please open a new topic for that. and before you do, try to come up with the smallest possible amount of complete code that demonstrates the problem. Nobody wants to debug...
