Another relevant link is resilient MQTT which provides an asynchronous MQTT interface which can recover from outages. It offers true qos==1 service: if the WiFi fails a qos==1 message will be passed once connectivity is re-established. If you plan a DIY approach, expect to spend a great deal of time...

The usual way to program MicroPython devices is as follows. Make no changes to boot.py (or absolutely minimal config changes). main.py consists of a single statement: import my_module my_module.py contains your code. That way you can develop your code at the REPL with an empty main.py. When it's wor...

@jaichhier I suggest you read this guide.

Ah, you're right. Been spending too much time with Pyboards

This forum supports MicroPython. CircuitPython is the Adafruit fork of MicroPython, and their SSD1306 driver differs from the MicroPython version. I don't know if Adafruit support using different fonts. A search on their forum or a query there might produce results. There is unofficial MicroPython s...

The commonest cause of corruption is when the flash drive is configured for MSC (mass storage) mode. The nature of mass storage devices such as USB sticks is that the PC expects to have full control over the (presumed dumb) drive. If the device makes any changes to the filesystem all bets are off an...

What IDE or development environment are you using? Perhaps that is setting the time. Note that the RTC will continue to run through a reboot.

The simple way to set the time is to acquire internet connectivity and run ntptime which gets time from an NTP server:

You might like to watch this talk by Damien which sheds a lot of light on this issue.

@smith.randallscott For your test to pass, several things have to happen correctly and in sequence. main.py has to run The ESP32 has to connect to the WiFi network, waiting until the connection is successful. It then has to connect to the broker, again waiting for success. Finally it has to make a s...

@ajocius Unless you have a reasonable knowledge of electronics I would look for a commercial motor and controller designed for opening and closing a door, and linking that to your ESP32. A DC motor or linear actuator would be ideal for the job, but we're talking about a fairly powerful machine requi...
