Hello,
I have a question. So far I have only configured contact, temperature or GPS sensors in Node Red. Receive and process data from MQTT to send emails or SMS or operate a dashboard. So far so good.
Now I want to monitor an emergency exit with a contact sensor. The scenario is already set. Now I want to install an additional LoRa alarm detector (MTC-EU-AU01 from Mutelcor) that should emit an optical signal when the door is opened. So it receives from the contact sensor?! What would such a flow look like in Node Red? Thank you very much
