Support for EZO I2C Sensor

[chris3600410]

#Hello everyone, I would be happy if EZO sensors can be integrated here

https://github.com/Atlas-Scientific/Ezo_I2c_lib

Some have already been added in Tasmota ... but I would rather stick with Raspi

Which sensors do you have? The Tasmota implementation seems rather basic, do you need anything else?

I won't be buying one of these to test, but I can implement it "blindly" for you to test it.

@chris8519 Thanks, I will have a look and will get back to you for testing.

Note to myself: have a look at this:

I have everything connected now ... you can maybe try to integrate that so I can test it ... greetings

Hello @UncleSamSwiss,
did already something happen here? If not I will have a look maybe.
I have a running Atlas DO Sensor on a pi4 with dev-server installed, and currently I am investigating your implementation.

Hello everyone, update on this Topic:

I have investigated this topic deeply meanwhile. As the whole EZO Protocol differs quite a lot from the ioBroker.i2c implementation and is not related to "standard" i2c Protocol and readings I think it makes sense to make a separated Adapter for this. The changes would require changes up to the device-handler-base class. I will start the Development of a new Atlas Scientific Adapter soon and will publish the repo after MVP implementation here.
