Has anyone tried to connect arduino that has multiple sensors to talk to esp32 that is running on esphome of HA
Why wouldn’t you just run everything in ESPHome and cut out a device?

To give a arduino a second life as port extender?
For other type of usage just connect your sensor directly to the esp32, should be straight forward
Thank you for your response, I tried port extender and realized it used for digital and analog pins extender…but since I had a setup whereby I am already using 6 arduino mega WIFI so I would like to migrate arduino mega sensors data to esphome as sensor values, My idea is to have them as slaves to one esp32 via i2c protocal
