I would like to read from i2c device (PH EZO Atlas Scientific) (https://www.atlas-scientific.com/product_pages/circuits/ezo_ph.html)
I can read out the PH sensor using a Python script so hardware wise it's working fine. But I would like to integrate it into Dashboard from Node-red.
The python script starts and the you need to input some command manual like: Poll,2 or R or I
I found a flow https://flows.nodered.org/flow/80fa54d83213202e33d599483a6a8fcd but it uses SERIAL and I don't have serial connection. I have only i2c connection.
I installed node-red-contrib-i2c and the settings ask for COMMAND and it only accept numeric not Poll,2 or R or I. Address is no problem this is 99 so OK
Is there a solution for this?
