Hello,

here is the solution: https://community.home-assistant.io/t/arduino-port-expander-i2c-connection-not-recover-after-failure/745984
In the end decided to use modbus because i needed to breach a longer distance what i2c was not able to handle

Hi @glmnet,
any chance you make a version for Arduino Mega 2560?
I've been using a modified version from @thebradleysanders in the last years, but with the migration from custom to external components I've lost the possibility to update my devices with the latest versions of esphome.

Thanks. Bye,
Vito
