Ok great, thank you for taking a look. Yes I2C is too short range for the applications I have in mind, but I have some experience with RS485 so that sounds like a good option.
I’m not very familiar with your ecosystem, but would using ModularSensors require the Mayfly to be connected directly to the sensor? So if my sensors are natively I2C, I need to put a microcontroller next to the sensor and then implement RS485 (or SD-12 / RS232) there to communicate with the Mayfly, right? Then I would implement the combined sensor in ModularSensors? Just trying to get a handle of the expected pattern here.
