Project – replace sonoff failed temperature & humidity sensors

2023-08-04 – the zigbee temp & humid sensors “cave” and “outside” no longer updating. stuick at some value. transmits, but values never change.

  • reboot hass; no better
    power cycle sonoff zigbee bridge; no better
  • power off//on the cave sensor; no better
  • battery? measures 3.2, requires 3, so good; try new; no better
  • did i kill it by leraving outside? good for -10C, so didn’t get that cold , but was below zero.

pressed the buton on dining room sensor; 5 seconds, then it blinks 3 times red. seems to make it update, since now its readsing

even after 2 hours, no change (there is discussion that the tmep reading is ~1hr intervals unless fast chaning ); reset again; no better.
pressing reset 5 secs on outside sensor does nothing other than flash the led red 3x


2023-08-15 – now the new display unit in the library has locked up values but is still tranmitting? is battry dead?

try to reset
