Thanks! Seems to be the right direction, but haven’t figured out how to use it yet.
example: http://remote:remote@http://192.68.1.23//scada-remote?m=json&r=grp&fn=write&alias={grp}&value={value}
Generated three channels of this device, requests, notifications and response status..
I guess there is a way to pass the parameteres GRP and VALUE through the formula field of the request channel? Or maybe I miss something substantial in the process? Will try more tomorrow…
