@jawoodfield - Before I comment more…Your timeline would be about right from a full charge to going offline without much opportunity for charging but have you monitored/looked at the timeseries data for the battery? Since your unit was brand new in the middle of winter, you don’t really have confirmation data that it had been charging properly (my unit ran all summer and fall, so I know it worked well in that regard). That may be something to investigate just to check that box of the potential list.
I haven’t found a solution in all my reading that I like. I have had my unit pop on twice since it first went offline (so assuming some good sunny days… it should charge… thus my unit doesn’t seem to be the issue… just my property). So far my thoughts from reading and monitoring the help community here have been:
- Acknowledge that the unit wont work in the dark months (Nov-Feb) without something changing - this would be an expensive bummer and I like to think its not the solution.
- Wait for the powerpak upgrade - sounds like it could be here before next winter.
- Taking the unit down to charge with artificial light indoors - this is a chore … and I don’t want to bias my “climate record” or “calibrations” with indoor data or inconsistent siting information after install/reinstall (but if data points/ranges could be flagged by me as bad? i suppose that would be a small encouragement).
- Run an extension cord to charge the unit outside with artificial light - i can do this… i think… my unit might be at the end of my extension cord length and I wouldn’t want to do it while its raining (which is pretty much all the time right now… and I would have to get my lamp up to 2+m high… oof maybe this isn’t it either) Perhaps this is a good task for a coming weekend?
- Move my unit - other than lifting my unit up in the air more to perhaps increasing the exposure duration (an engineering task to set up guy lines and the like for any appreciable change). Unfortunately, I think my current sighting is optimal given my property - its in the center of my cleared land away from nearby obstructions/buildings (but not so far as to not have a wifi signal). I do have a barn that I’ve contemplated installing it on the top of… but it would be a trade off to some extent as it would be higher, but closer to the treeline and probably have its own microclimate due to roof heating and wind eddies and arg… I don’t have the bandwidth to do optimization tests for light levels around my property for what might only be 1-10% enhancement in light at the expense of other characteristics.
In the meantime, i have an old P/T/RH/WS Accurite sensor and a wealth of RH/T IOT type arduino sensors around to keep me busy and patient. Given the tech embedded in this sensor (i’m sure its neither trivial nor easy to manage the power) and in the backend systems, I still believe in the product and have faith that the unit will surpass any other consumer met package. The commentary on this page here makes me hopeful and the longer days do too… I’m guessing with no modifications, my unit should be up in a month or so.
