Hi, I am using the Automation/Irrigation Hat - V10 and it is working perfectly fine toget her with the 8-relay board.
I would like to add more than 5 digital sensors to the system, but there are "only" 5 GPIO's on the board.
What would be the easiest way to connect more digital sensors (apart from getting I2C sensors :0)
Can I connect them to the available multiplug, where relay board #2 could be connected?
Brgds

Hi, yes you can connect to the relay2 connectors, so you will get additional 4 gpio available (as the other 4 are already shared with relay2). If you want to have some fun, you can try adding sensors using WiFi and the ESP module. As a curiosity, regarding the I2C , I had indeed a working prototype of my sensor working with the I2C interface, then I realized that the I2C couldn't be used for cable length more than 1 meter, it was definitely not so useful so I implemented the current protocol.
