I think there is an option to upgrade the battery to have a 240mi range

I had one of these for years, it grows like crazy if it’s given the space. The branches will get tall and start to droop, then new branches will sprout in to fill in the new overhead space. Otherwise lots of trimming and pruning will expand it also.

I don’t know about FOSS, but Tasker is probably the best bet for phone automations.

Edit: Found this LibreTasks
