Hello,
I use node-red to communicate with Siemens s7-1200 and Alexa. My problem is when I do the command in Alexa to activate one DO in the PLC. The command is for activate light. I do the command to turn lights on in Alexa and I turn off in my HMI. When I see the state of the switch in Alexa he show me ON. Whoever the lights are off because I turn off in hmi. Anyone can help me to resolve this situation?
Best regards
Marco Wilson
