I have noticed that in the latest Vera firmware if a variable has no value it does not show up in the Advanced -> Variables tab.

Try writing some value manually from Apps -> Develop apps -> test loop code (here is an example):

luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_4", value=1}, 24)

24 in the example is the Id of the MySensors plugin Main device.
11;3 in the example is altid of the sensor node device.

After writing and refreshing of browser (Ctrl + F5) you should see the variables under Advanced -> Variables tab

The command should also send the value to your child node.

@gohan said in Which dust sensor do you use and why?:

@korttoma if you have a library that can read the values from the sensor, you can easily add the mysensors code

yeah I know, I just thought that if @NeverDie already made a MySensors sketch I would not have to invent the wheel again.

@NeverDie what lib are you using and how? I2C?

@neverdie

Just received an Plantower PMS5003 allso, do you have a "MySensors" sketch that you could share?

@vladimir there is an example for using rotary encoder on this page:

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.
