@kurthofman Whenever you boot up the device and select setup > change wifi connect and setup a new wifi connection it will be added to a list on the same page as the change wifi connect menu
@jpilarski take a look at the I2C hub from Seeed; only problem is how many milliamps your I2C sensors need. My multichannel gas sensor (from Seeed) cannot run on the bus while the BME280 is on at the same time. btw addresses are configured properly.
