I would just add that I made up various meshtastic nodes with XIAO units and placed them inside pill bottles with neod-magnets on the base then used a 3/4 inch PVC pipe with a mating magnet. the unit was pushed up into the crotch of a tree. This worked very well for temporary… Only problem is LoRa is strictly line of sight… I always say it will transmit to the moon if you can see it… not sure that is 100% but definatly have pinged off aircraft at crusing altitude and seen those aircraft relay messages from states away…. if a tree branch or trunk is in the way… the relay will probably not happen to/from that direction… I would recomend maybe installing a flag pole so you can run the unit up and down…
I would recomend the Meshtastic Device - SenseCAP Card Tracker T1000-E at one time seeed produced a kit that came with multiple units/ and a case with multi charging bank… at this time i cannot find the link
