@thierryd Nice idea.
Two remarks:
You write in the cpp file:
if (BatteryType == 2) {
/* LiPo voltage ...
You probably mean here "AA voltage"
The AA batteries you talk about are Alkaline (not rechargeable)?
The values are different for NiMH rechargeable (which I always use).
@gohan yes it confuses me too. I have a similar situation where my node with 2 sensors is recognized by Domoticz as 3 devices like: Temp, Hum, Temp+Hum.
Apparently Domoticz is able to recognize that the different sensors belong together, but sometimes, there is a disturbance or bad reception in one sensor message, and then Domoticz creates a new device for it.
That would not be such a problem, except that you do not know which device to show on the Domoticz dashboard. Personally, I choose the combined one, ignore the others, and live with it.
I do not know if this is a bug for the Domoticz people, maybe they can resolve this?

Oh, I just remembered, a 4051 contains a 1-of-8 multiplexer, and is cheap.
Look also at the 4052 which contains two 1-of-4 multiplexers.
Search on ebay for: 4051 DIP
I would use a 4067 IC for the analog voltage, and probably a second 4067 to switch the power. Then you will only need one analog line of the Arduino, and a few digital lines.
See http://assets.nexperia.com/documents/data-sheet/HEF4067B.pdf
The 4067 is one of the 4000 series CMOS chips, which work with 3V to 15V power supply. It contains a 1-of-16 multiplexer of analog switches. For a smaller number of analog switches, you could use 4016 or 4066.

@meddie : Sure, I can:
The following is an extract from the code shown at https://www.mysensors.org/view/1/Sensebender-Micro, from the "loop()" function:
#ifndef MY_OTA_FIRMWARE_FEATURE
if ((measureCount == 5) && highfreq)
{
clock_prescale_set(clock_div_8); // Switch to 1Mhz for the reminder of the sketch, save power.
highfreq = false;
}
#endif
If you remove these lines, it will stay on 8MHz.
(I did not test this but I am quite sure)
@tbowmo : The code to switch the frequency back to 1MHz is still there at https://www.mysensors.org/view/1/Sensebender-Micro.
Should it be removed?

OK, I understand.
My confusion was caused by the second sentence at https://www.mysensors.org/hardware/micro : "... it operates at 1Mhz ..."
That's a mistake then?
To reprogram the sketch in a sensbender micro, wich processor frequency do I choose?
After choosing Board "Sensebender Micro", the menu in Arduino 1.6.12 has choice Processor "Atmega328 8MHz" and "Atmega328 1MHz".
My code seems to be executed equally fine with both settings.
But the Arduino Serial Monitor not:
If I choose the 1MHz version, the Serial monitor only produces garbage, whatever setting I choose for baud (in the sketch and in the serial monitor UI).
If I choose the 8MHz version, the serial monitor works fine.
I am confused. The Sensebender is a 1MHz device, isn't it? Is it able to run on 8MHz too?
