How-To Compile this Project ?

[Noschvie]

Is there a How-To get this compiled and running ? Thanks!

[FKW9]

Are you using PlatformIO? Otherwise i can't really help you

[Noschvie]

Have installed Visual Studio Code and extension "PlatformIO IDE for VSCode". Please find below the output with warnings, BIN file seems to be created, isn't it ?

Yes, this was a successful build. Can you upload it to your ESP? BTW check the selected environment, you built it for ESP8266

[Noschvie]

Visual Studio Code is running in a virtual machine, recompiled for ESP32.

Using ESP-Flasher-Windows-x64.exe leads to this output:

Is the last part the serial output of the ESP? If you get this Message after line "Showing logs" continuously, it seems like you are stuck in a boot loop, but i cannot tell from this log.

Are you receiving messages from the ESP? You can check this by connecting to the serial port on which your ESP is and restart it and you should see messages appear.

[Noschvie]

Something is missing to get this firmware running. Flashing Tasmota to this ESP using ESP-Flasher-Windows-x64.exe leads to a running system.

Have no display connected and tested with disconnected / connected M-Bus interface. Any idea ?

[FKW9]

Sorry, i do not really understand what's your problem.

The warnings seen in here can be ignored. The ESP should print something to the serial port (when booting), with or without the connected hardware. Please check that first.

Fix #3 solved this issue, thanks!
