I wander if I just alter that file to stop any polling via ebusd and only use the manual script if that would be better.
Hopefully get an hour to play about with it over the weekend. I’ll try what you have above, and note the bits that get updated each minute, then possibly just narrow the manual 60s poll to things that arn’t already being done.
Either that or I can try a command to space out the requests by 5-10 seconds each, so only asking for a little data at a time.
