Yes, I did a straight swap and now, after over a week, the battery level hasn’t dropped at all.

@martinb
I replaced the NRF24L01 and now the power consumption has dramatically reduced. Thanks for all the help, as I’m new to MySensors it helped to eliminate other potential issues.

I'm beginning to wonder if it's the NRF24L01 that's the problem. I found this post which might explain my continuous power draw.

@mfalkvidd
Yes, I'm using pin 3 which is opposite A2

@mfalkvidd
The current draw is the same whether the reed switch is open or closed. There is a momentary increase after a change (which I assume is the radio drawing additional power to transmit?)

@mfalkvidd
It may be my terminology! It's using digital pin 3 (just marked "3" on the Arduino)

@mfalkvidd
That's correct, no further log activity until the next change in state of the door

@mfalkvidd
It looks as if the node is going to sleep OK, as I get this from the nodes debug log:

7116 MCO:SLP:MS=0,SMS=0,I1=1,M1=1,I2=255,M2=255
"Sleep node, duration 0 ms, SmartSleep=0, Int1=1, Mode1=1, Int2=255, Mode2=255"

7122 TSF:TDI:TSL
"Set transport to sleep"

@zboblamont
The current draw is the same, whether the door is open or closed.

@yveaux
I did follow the build instructions in your link, with the reed switch on D3. When the door is closed, the reed switch is closed (conducting).
