h16bill:
So how long did it run with 4 AA batteries?I have a similar project.
Cheers
Bill
Using the setup described above (with a small difference: the deepsleep last 2 sec, not 5 seconds), I had a very good first run with 4 AA from 29/07/2018 to 03/10/2018.
Then I run into some troubles and I had to change the board. I went for a Lolin which is so much easier to "modify". With that board i got 2 month and half of battery life.
For the record, I ended up with using the main power and a lithium backup battery, with a special circuit to keep the battery charged.
