Ruuvitag placed in sailboat salon on 11/10. Last upload to Victron VRM on 11/18. 2 weeks later, (12/2) removed from boat with battery at 1.8v. Replaced battery on 12/6 and red led is solid and Ruuvitag is undiscoverable by iPhone with Bluetooth or NFC.
Another Ruuvitag is still working on boat under the same conditions.
Is there anything I can do to revive it? It has a single button and I tried a short push and a long (10 second) push. Still has steady red led.
