I am new to node red and can't seem to find a fix for my issue.
Node red is being run on my pi 3 model b that is connected to ardunio uno via usb serial link. I am able to get the data from the serial.print from the ardunio to show in node red using the serial in node.
Connected to Ardunio UNO:
1x Temperature sensor
1x water flow sensor
1X RTC (Not updated with correct time yet)
1x PH sensor ( ignore this one for now )
For reference please see below:
** connecting debug node to Serial in log**
What I am trying to do is display the readings (values) coming in from the serial in onto separate dashboard gauges.
The advice I find online says to use a switch to filter the strings However on the debug log for the outputs on the switch I either get no readings or the same reading as the serial in
For reference below
As you can see from the screen shoot above the readings are the same as the serial in and pulse though all the readings shown in the debug at the top of the post.
Any advice will be appreciated to get this working
Thanks for reading
