I am trying to send a signal in hour I want every day but if I put 14:30 it sends at 16:30, and if I put it 12:30 it sends at 14:30. How can I correct that?
Check the time zone settings on your server
I can´t find the setting of Node-Red to change the time zone settings...
Node-RED takes the time settings from the server that it runs on.
the server is running on the right time.
What OS are you running the server on?
