We created a node red script that will basically OPEN relay 1 for a moment on our cerbo gx if it detects no internet for 1 hour.
This will reset our network switch and then turn it back on if it locks up.
We have a 24v to 48v DC to DC convertor hooked up to the “normally closed” on relay 1.
The convertor has a “remote on/off” port that basically acts like a switch. You would want it closed for the most part and only open when you want to cut power to the convertor.
The script works great from testing… but we are having an issue with the relay just jumping open randomly.
This convertor powers a network switch that is required for us to remote into our setups. So we CANT have it randomly turning off and back on.
We thought it may be our node red script at first, but completely disabled the flow and the issue still happens with the relay set to “manual” on the cerbo.
If we set it to something like “temprature” it never has this random relay OPEN issue.
If we set it back to “manual” it will randomly go open (which boots our network switch) even with rode red flow disabled….
Any ideas?
We have only 12 setups like this and more than one seem to have this issue so it’s not just one.
