(edit : thanks Heather this is post had got stuck) @rogers1313 great to hear your project (from your posts in the https://www.envirodiy.org/topic/mayfly-v1-1-technical-questions-forum-thread/#post-17333)
– thanks for filing your profile https://www.envirodiy.org/members/rogers1313/profile/
I’m similar EE/and FirmWare – https://www.envirodiy.org/members/neilh20/profile/ – youre welcome to email me dreictly, but this is also a good place for discussing how to deploy.
Matt is also deploying for TU https://www.envirodiy.org/members/mbarney/profile/
This thread may be of interest – I’m targeting my fork for easy deployment and reliable delivery of readings .
I’m scaling some systems for Tu N California, and documenting some of it through this (but an open source wip).
For low cell phone service I’m using an android app “Phone Signal” https://inpocketsoftware.com/phone-signal-cell-strength-overview/ for doing a survey.
A note, IMHO the core https://github.com/EnviroDIY/ModularSensors works for where there is reliable phone service – excluding some 90% of potential coverage range where the cell signal may be marginal.
