@bjornhallberg @Koresh That's what I wrote a few posts above - start with the capacitors

My suggestion - get a decent DMM. Brymen BM235 or 121GW or any Fluke.
Measuring a sleeping current is challenging and some unexpansive Chinese DMM manage it just really well. BUT! You do not want to waist your time just because your meter is crap and was completely off on some readings.

@bjornhallberg

1. No - please double check the board. There are options for a few sensors. Which ones do you have. Sensors on board.

2. Code really depends on sensors on board you have.

3. This is not about counterfeit radio. Just radio NOT SLEEPING. That's it.

4. OK.

5. OK

First thing first. Let's deal with your sleeping problem.
Identify which sensors you have on board or post a good quality photo of the board.
Try to use minimum sketch (see commends below - choose the correct Mhz band):
and measure the current

#define MY_DEBUG
#define MY_RADIO_RFM69
// Please use one!!!!!!
//#define MY_RFM69_FREQUENCY   RF69_433MHZ
//#define MY_RFM69_FREQUENCY   RF69_868MHZ
//#define MY_RFM69_FREQUENCY   RF69_915MHZ
#define MY_NODE_ID AUTO
#define MY_TRANSPORT_UPLINK_CHECK_DISABLED
#define MY_PARENT_NODE_IS_STATIC
#define MY_PARENT_NODE_ID 0

#include <Wire.h>
#include <BH1750.h> //Make sure you are using this one https://github.com/claws/BH1750
BH1750 lightMeter;
#include "SparkFun_Si7021_Breakout_Library.h"
Weather sensor;
#include <MySensors.h>
#define SPIFLASH_BLOCKERASE_32K   0xD8
#define SPIFLASH_CHIPERASE        0x60


void setup() {
lightMeter.begin(BH1750::ONE_TIME_LOW_RES_MODE);
  noInterrupts();
  _flash.initialize();
  _flash.sleep();
  interrupts();
}


void loop() {
lightMeter.begin(BH1750::ONE_TIME_LOW_RES_MODE);
lux = lightMeter.readLightLevel();
Serial.print("Lux="); Serial.println(lux);
sleep(10000);
}

@yveaux you are quicker than me ;-))

You cannot beat this guy

@bjornhallberg I have the same v1 board you have with a sleeping power consumption being 5uA. I also have Si1132 sensor soldered and had some issues with power consumption initially as the standard Si1132 lib did not implement sleep function for this sensor.

1. what sensors do you have? Do they properly put to sleep? BH1760?
2. can you share the sketch?
3. removing the LDO will not help you to bring down consumption from 3mA. 3mA most likely mean your radio is not sleeping. Such consumption will kill CR2032 very quickly - no chance running the board on such consumption
4. did you try a different multimeter?
5. there could be a problem with one of the tantalum capacitor. @yury could you remind which one has to be removed please?

I suggest you start with 5)

@rejoe2 Interesting. I'll try it

@mfalkvidd Yes, I have gone through that. Domoticz does not recognise tty if it does not like it. I have

/dev/ttyAMA0

Hello,

I have several GWs in Domoticz. However, only one (MySensors Gateway USB
Version: 2.1.1) never shows up its version in "Domoticz - Hardware" unless I press reset button on Moteino.

This is a Moteino Mega with a trace antenna connected to Raspberry via TX/RX.

All other GWs (ethernet ones) are working flawlessly. Just to summarise, when Domoticz is rebooted, only one USB GW shows "?" in the version section. When I press the reset button, the version comes up as 2.1.1. Upgrading to 2.3.0 does not help - any idea how this can be corrected please?

I have abandoned an encryption idea for now as I do not have too much time to troubleshoot it.

@mfalkvidd Let's put it this way, everything works smoothly without encryption. However, as soon as I upload the same GW sketch with encryption (both GW and the node have the same AES key). GW is seen by Domoticz and the node just becomes invisible. I can see there is a successful communication between the node and the GW (sadly I did not save the log). Something fails at the GW level, but you gave me a hint:

he messages will be decrypted by the gateway before they are sent to the controller
