Revpi 4 Connect Digitial In
Hallo zusammen,
der RevPi 4 Connect hat einen Digital In, laut Handbuch für die Überwachung einer USV. Kann ich den DI zweckentfremden und auswerten in NodeRed?
Danke und viele Grüße

Re: RevPi4 Connect RS485 NodeRed
Thank you so much ...
That was the hint. It works now. Also many thanks for the information regarding "/dev/ttyRS485-0". I changed it now under Bookworm, so that should work with Trixie.
Many greetings
