Now my next challenges is to connect a PT500 to analog input of unipi and read the value.
Tried this function but it does not work
var status = JSON.parse(msg.payload);
var newMsg = {};
if (status.dev == "ai" && circuit == 1 )
{
newMsg.payload = status.value;
return newMsg;
}
this is solved; for all others who have same problem enclosed my solutions. Any comments and improvements welcome
howto for 1-wire temperature via nodered?](/topic/444/howto-for-1-wire-temperature-via-nodered```Hi there,
I have just started, using unipi 1.1 + rpi3 and running rodened+evok
Excuse me my dummy question but i cannot find any informaiton howto read temperature of a 1-wire temperature sensor
Do I need to install owfs for this or can I just read the temerature via a function node?
How do I get the address of the 1-wire temperature sensor?
Do i need to configure anything before 1-wire works?
Sorry many perhaps dummy questions but would be great if you can point me into right direction or have an example.
Many thanks
