May be... but I tried also other 2 sensebenders without FTDI programmer (using the pre-loaded sketch) with out results. So I guess there is something else wrong.

Hi there!

I bought 10 Sensebender Micro a couple of month ago, and finally was able to play with them during this weekend.

I opened 3 of them and try to load a sketch on in just to try the FTDI programmer (I have been using UNOs and NANOs to avoid this until now!), but get the following output from the Arduino IDE using Sensebender Micro, Atmega328 1 Mhz configuration:

Sketch uses 25,350 bytes (82%) of program storage space. Maximum is 30,720 bytes.
Global variables use 814 bytes (39%) of dynamic memory, leaving 1,234 bytes for local variables. Maximum is 2,048 bytes.

The Sensebender Micro LED is always solid red, except when the sketch is uploading when it turns off.

I was unable to read using the self-test-mode anything on the Serial Monitor.

I also try with 2 more Sensebender Micro, and always get the same solid red LED with and without radio.

I tried also to add them to my Domoticz environment (with several sensors) and was unable to read anything from them.

Not sure what else to test, nor what the solid red LED means.

Any help would be greatly appreciated!

@mfalkvidd Hi there and thanks for a great and super detailed step-by-step tutorial.

I've got mine running in no time with your instructions, but after a couple of minutes I've got the following error:

2015-12-30 20:51:30.356 Error: MySensors: Unhandled sensor (sub-type=32), please report with log!

I also attached a partial screen capture showing that it was working before 8-)

Any idea on why is this happening and how to solve it?

Southern regards and happy new year to all!
