We have a MultiPlus-II and 7kWh of PT batts running as a UPS for our media servers in our business, and we need a way to command the Qnap server to shut down at a set battery level. Does anyone know of someone who can write code to make an SNMP signal from a MultiPlus-II or a Cerbo GX, if required? Thanks
Not a straight answer but what you describe can be achieved with the in-built Node Red and with Home Assistant (you need a computer for that) or even an external relay.
I use an ssh-v3 node (node-red-contrib-ssh-v3) in Node Red.
This node can login on a Linux system or Nas.
You need ssh access on your QNAP and run a shutdown command.
On your QNAP the command is /sbin/poweroff
Thank you both, will look at this when we have time. sounds like alot to learn and apply. HNY
