Hi
The RevPi Compact does only support 2 wire PT100 RTD, which must be connected to an input and it's 0V pendant. If the sensor is only available as 3 or 4 wire variant you could use an external temperature temperature transducer (converts the rtd to 0-10 V / 4-20mA)

Hallo Andreas,
ja tut es. Der Node Red Docker versucht den selben Port zu binden. Highlander Prinzip

Re: Modbus Connecting Probleme
Hallo Ingo,
wir haben leider noch keinen SOS Report von dir enthalten, welcher für uns wichtige Informationen enthält.
Was für ein Core ist das eigentlich? Ein Core 3(+) oder einer der ersten Generation?

Re: Measuring Current Loop - Module is Present but not configured.
Looks like your wiring is wrong: brown should be connected with the positive voltage of the power supply white should be connected with the positive terminal of the AIO a ground wire must be connected to the negative terminal of the AIO The current you want to measure flows through the sensor Nicolai

Re: Digital Out Pins briefly switch to HI when booting
I will have another look. At the moment I'm not able to reproduce a measureable glitch on power on. Which kind of relais are you using?

Re: Digital Out Pins briefly switch to HI when booting
Do you actualy measure output voltage during power on or just observe flickering of the output LEDs?

Re: Measuring Current Loop - Module is Present but not configured.
A flashing red LED indicates Range error. A too high a voltage or too high a power supply at one or more inputs. Check the input status in the process image. https://revolutionpi.com/en/tutorials/uebersicht-aio-2/status-leds-revpi-aio-2 What is the voltage of the connected sensor? Could you please s...

Re: Digital Out Pins briefly switch to HI when booting
Hi
Could you please test if the following fixes the problem for you?
1. Download the attached archive and extract it
2. Copy the file to your revpi as `/boot/dt-blob.bin
3. Reboot

Re: How to unplug individual wire of PCB connectors
If you're using ferrules (depending on the crimp pattern) it can be sometimes helpful to twist a little while pulling.

Re: RevPi Connect: Zugriff über 2 Netzwerkkarten
Hi Christian, wenn du ohne extra Routen aus dem einem Netz auf einen bestimmten Port (z.B. vom Webinterface) eines Gerätes im Sensornetz zugreifen willst, würde ich mit Portweiterleitungen arbeiten. So aus dem Kopf: iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 192.168.0...
