Hi again HB, prompted by your story I thought I would go look carefully at one of my own LHT65’s - this is deployed at a remote site in the north of England, so I cant make physical checks only look at received data - installed July/Aug’19 running at SF7 under ADR (so likely also with slightly reduced TX power as with very good signal level & conditions to nearby TTIG as GW. Little battery drop so far - if anything the slightly warmer weather over the summer has helped recovery. Note update rate is every 20mins, and unit also has an external temp probe so reporting T&H directly along with additional T.
Are both of yours the same distance, and essentially the same or very different signal paths, to GW - such that one might be commanded to run at lower TX pwr if both on SF7? Tx will have significant impact on battery life…are they configured for ADR?
