I am running ewpe-smart-mqtt on Raspbian Stretch 4.19.66. I am using node v12.10.0 all other OS components were upgraded. On npm start i get (after detecting my Hunter/Cooper airco's) a decryption error: npm start

ewpe-smart-mqtt@1.0.0 start /home/pi/nodejs/ewpe-smart-mqtt node index.js

I also tried npm install eccrypto but that did not help.

I fixed it myself. Had to do: sudo apt install libpython3.5-dev
