Which provider? Which device? Where's the full documentation?
Anton, can you help me with what command can I activate/deactivate the output?
It uses MQTT, right? I'm not sure we support commands for it currently.
Actually wait. We do support output control command directly.
thanks for the feedback, I'll use MQTT. I'll wait as long as necessary
Will I be able to send commands or do I have to wait longer?
Have you tried?
yes, many times...but I really don't understand what combination of numbers to write in the command. I've tried everything
You don't need any combination. There should be a dedicated command type.
I want to control output 1, but data must be entered there. I assume for an on/off output.
I tried with the B0 B1 provided in the documentation, but it doesn't work, I tried to convert them to HEX, but I also have no success
Can you provide a screenshot?

The value should be 0 or 1.
I can't figure out what I should write in the data field when sending a command.
This is what the gps provider sent me .. Please help me
