    • RE: Send pH, Redox and temperature values to domoticz

      I try to change the pin 2 by another but my lcd doesn't works.
      I don't know if it's possible to change the assignment for the pin lcd.
      To put in place the lcd I have used a tutorial. I have a look on google but a lot of tutorials have the same pin assignment.

      Oups!

      Unfortunatly, my LCD allready use the PIN 2 of the arduino.
      As I need to connect my NRF24L01+ on my Arduino mega, I need to use the PIN 2 also for the RF.

      Do you know if it's possible to map the LCD on other PIN?
      For the moment, it's map like this:

      LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

      Thank you for your help

    • RE: Send pH, Redox and temperature values to domoticz

      I have a look at https://www.openhardware.io/view/381/Floating-Swimming-Pool-Sensor-Water-Quality

      In fact, in my arduino code, I take the average value of the ph and the redox to keep stability of the values. I record it into 2 variables:

      • float pH
      • int Redox

      So I have to use the "var1_msg( 0 , V_VAR1 )," to send my variables as I can see in the "sensor water quality" project.

      I will try this

    • Send pH, Redox and temperature values to domoticz

      Hello,
      In first time, sorry but my english is not very good.

      I will explain my project:

      I put in place a pool regulation with an arduino Mega and an LCD screen.

      • pH value of the water pool
      • Redox value
      • temperature of the water
      • pump to inject Chlore for the redox
      • pump to inject acid for the pH

      My system works as I want.

      My next step is:

      • Send the pH value to domoticz ( between 6.8 and 8.0 ) (float)
      • Send the Redox value to domoticz ( between 400 and 1000 ) (int)
      • send the temperature value

      I would like to be able to control the light and the heat pump of the pool throught domoticz.

      I allready have some mysensors nodes at home ( light level, temperature and motion sensors ) wiches are working perfectly.

      I don't know how to send the pH and the Redox values
      It will be kind of you if someone could help me.

      Best regards
