Not an issue - Video on how to convert and setup the particle sensor #20

Hey @Hypfer I made a video on how to convert and setup the Vindriktning sensor. If you want you can add it to the readme, as it will go through all the needed steps. There is also a German version of the video, which is also linked from the English version 😄 https://www.youtube.com/watch?v=NwHL8XMarFY

I would still go for the extra protection using the voltage divider, as I remember correctly I killed an ESP8266 before supplying 5V to a GPIO. So better stay on the safe side.

When the device is configured, how can I reconfigure it a second time to select another mqtt broker?

enwi commented 3 years ago

@Q7Jensen that's still a todo, but afaik if the device can't connect to its configured WiFi network it goes into AP mode and you can reconfigure.

I'm fighting with this, too. Somehow, the mqtt server was reset not by my request to example.tld and now I can't reconfigure it (first it worked). Even formatting the SPIFFS didn't work.

addendum: I fixed it with erasing the Wemos completely with esptool and reinstalling the sketch:

esptool.py --port /dev/tty.usbserial-34440 erase_flash
