Ideas to port this to ESP32 ?

[waltsteinchen]

The ESP32 could replace the ATMega easily and has built in Bluetooth so one module less needed in the end.. Any brain-work already done into that direction ?

It could be quite easy to do the job, especially with micro python. Maybe latter, I want to build one as indicated before to think on another version. I also have a 3D printer and plan to design a box.

done that. had a few issues with the esp32 SPI timing, but works ok and uploads data to mqtt.

idoroseman,your sketch reset esp32 every reading

hi @melanrz, it goes to deep sleep after each reading to conserve battery power. wakeing up involves a reset. is that what you mean?
