Not sure what I catch your question 

how counting of Zuno pins related with Zuno channels?!
AFAIK Zuno can implement 10 channels 

so you can have 10 switches 

actually I have tested 5 switches 1 temp 1 hum 1 pressure  1 binary sensor

  • Hi 10der, thank you for your rapid reply. There are 25 "digital" pins but some have additional functions e.g. PWM or INT so I am querying whether all 25 can be setup as ZUNO_SWITCH_BINARY(getterSwitchX, setterSwitchX) channels where X = 1 to 25?

     

    I guess you have answered my question - Zuno is limited to 10 channels so there can be a maximum of 10 switches. Can I ask which Pins these should be set up on? 9 to 18?

     

    Thanks again for your help. It is greatly appreciated.

  • Just following up on my query. Has anyone been able to use Zuno with more than 10 digital inputs/outputs? If so which pins can you use?

    My Z-UNO uses 9 relays (pin 10,11,12,14,15,16,19,20,21), 7 temperature sensors (pin 9) and 5 input sensors (pin 8,7,6,5,17)

  • Wow. Ok. That is a lot. Thanks as this is VERY helpful.

     

    One question how can you have 7 temperature sensors on pin9?

    The other Z-UNO uses a me 280 pressure and humidity sensor, 6 DS18B20 temperature sensors, 10 relays,
    and 1 sensor. Everything has been working perfectly for more than a year.

    the DS18B20 temperature sensors have different addresses and are connected to the same pin Z-UNO
