Dear Colleagues,

I'm facing some issues to get the relay 5v working, i have change from d0 and d1 but it does not work with mine nodemcu v3. Also i change from active low/high and few the same! D1 is not active and d2 is alsmot all active IN of my relay. May you help me to figure out my fault?

marceltech commented 4 years ago

Just to add something for your troubleshooting, when using the D2 it makes relay active all the time

Use Active Low Relay Type and Momentary option. It works by me...
