I’m trying to see if I can create a multisensor using multiple I2C devices. I know the ESP32 has 2 I2C busses, but I believe you can also “daisy-chain” I2C devices together on the same single bus (as each device is given a “unique” address for the communication between it and the ESP over the I2C bus) and this could be useful to connect two or more devices to a single I2C bus on the ESP8266. I’d like to use a I2C temp and humidity sensor (HTU21D) along with an ambient light level sensor measuring lux (TSL2561 or BH1780) which I’ll then add a PIR sensor to (AM312).
I’ve not seen much on this other than here: https://www.bluedot.space/tutorials/how-many-devices-can-you-connect-on-i2c-bus/
Can ESPhome support this setup?
