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 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
Hi RoryCodes
yesterday my solution arrived from Aliexpress.
I used the Atlas Scientific PH print and en UART device from Ali.
This works with the flow I already found!
it's solved. I've succeeded in reading the EZO RTD, EZO pH, and EZO FLO Stamps.
Where I struggle now is multiple byte command like 'Clear' to zero out the flow totalizer on the EZO FLO stamp. I'll have the same issues when I go to calibrate. Watch that thread that I referenced, as that's probably where I'll place my answers.
