Yeah, my 6075 device is also still working fine on the 2xAA batteries I put in it a year ago.

@madelle-kamois This has been done before. For some inspiration -> https://forum.mysensors.org/topic/157/diy-blind-control-motor

I found an ESP-07 so I uploaded the ESP8266 WiFi Gateway sketch to it an tested inclusion mode in Vera (MySensors plugin version 1.5) and it seems to work just fine for me. I used esp8266 Community version 2.4.1 in Arduino IDE 1.8.5 and MySensors version 2.2.1 -alpha. I'm really out of ideas why this is not working for you.

@mntlvr I got it from GitHub but it seems like the development version is now 2.3.0-alpha, not sure what has changed since I downloaded it.

@mntlvr sorry I do not have much experience with MySensors Library version 2.2. My 2 Gateways I run at home use 2.0.0 and 2.1.1. And my test GW (SensebenderGW) is running 2.2.1-alpha since there were some issue using RFM69 on the 2.2 version. Maybe you should try the development version also (2.2.1-alpha)? Unfortunately I ho not have any ESP8266 Gateways at the moment but I can see if I have one laying around so that I can test.

@nca78 I have now measured the current consumption of the small bluetooth beacon device (N51822 QFABC0) using your code and the results are encouraging.

With your code I get around 4uA sleep current compared to 800-4000uA with my old code

Measurements done with an Micro (nano) ampere meter (double) that has not been calibrated against a reliable meter so do not take the measured values so seriously but more as a comparison.

1.8.4 of the IDE should be just fine, I'm using 1.8.5. But you need to check the AVR Boards definition you are using. 1.6.11 is know to work but newer versions are known to cause reboots in Ethernet GW and this is what seems to be happening for you.

I'm not sure I understand in what situation you get the above. Is it when you try to start inclusion from Vera?
If it is then it seems like your GW is restarting and this is something that happens with some versions of the Arduino AVR Boards definition. Please check that you are using version 1.6.11 from the IDE Boards Manager (I think this is something that I have already mentioned to you in one of your other threads but lets check again).

@mntlvr If you now try to start inclusion mode from your Vera you should see some event also in MYSController.

@mntlvr In MYSController you just need to go to "Settings" and check "TCP/IP" and enter "IP" and "Port" and then "OK". And then you press the "Connect" button. Then you should see some messages under "Messages" and under "MYSController Debug" tabs.

Now try restarting your node to see that it presents itself correctly.
