Yes please try to update the bootloader first- I think it's quite interesting for the rest of us what is the actual rootcause
I don't use the stock bootlader in any Arduino codes, but instead an optiboot from GertSanders (as optiboot have enabled the WTD/watchdog)

@strixx
so did you change the IC ATmega328P or was it the whole Arduino board?
if it's the whole Arduino board, then Sundbergs suggestion that a cap is faulty quite likely the error

quote Sundber84: "

@strixx if you removed sensors like suggested above and you still have a high mA you should try to change the pro-mini. It could be a failing capacitor leaking."

Nice case
Sorry I'm teasing you - you can improve and create a lock that slides so you can avoid the screws. It's not my design I have only used it. Credit shall go to Arvin. He have done it quite clever in OpenScad so you can easily adapt dimensions

@tbowmo
Quite impressive arcade game

Looks good

Domoticz have a sensor timout, and makes the icon red if the timeout appears, so regardless it's required to occasionally (1 or 2 times per day) to send a "heartbeat"/alive message. I know this timeout in Domoticz can be changed, but it's a nice feature.

@tbowmo Looks good

Great that you solved your problem, I still recommend to replace DHT22 to a a better sensor that uses less current consumption and also is working with a lower voltage. This will save plenty of money else spend on replacing batteries too often

@ehome
If you need a minimum range of 5-7m have you thought of radar?

@sundberg84 said in 2.2.0 node - sleep() problem:

The best way to debug this is to remove the sensor and see what kind of mA you get. If it's still a high reading I would replace the radio.

Sundbergs approach is the right one, and if non of those are working, replace your Arduino
did you remove the LDO voltage converter on your Arduino Pro Mini? This will use current
clones are not 100% identical, so your clone could have the LDO positioned somewhere else:
