Thought the Problem was solved with the right Power supply, but seems not.
I think this is more a temperature problem.
When it goes under -6°C or less, this is when the PB appears...
Strange as the receptor is in waterproof enclosure, and when i open it, no humidy inside or condensation.
I replace it by another receptor and was the same...
This time, what happens, simply stops working after few minutes... The Green LED simply goes off and the red light stays on. (emitter is OK).
Maybe still a PB of voltage after regulator who goes down due to cold conditions?
Do you think using a 12v DC supply and a heatsink on 5 volts regulator can be a test to do?
Somewhere like with the MR16, where the main Power standard is 12 volts who goes directly to the 5 v regulator?
Some thoughts?
