Sensebender Micro
-
@Stric Did you get a "avi", or did they end up in the mail-box directly? I got a "avi" today but it might be also for any of the constant inflow of stuff from aliexpress... Can't wait for my 4 pieces Sensebender to show up! :)

My first Senseboard is now Up and Running. Have even tested to reinstall the sketch. No issues so far. Thanx for this product.

Picked up my four devices yesterday and two of them are up and running using the pre-loaded sketch and it works like a charm!
But i have a question regarding the battery level reporting, I can see the following in the code:
// Battery voltage is repported as child sensorId 199, as well as battery percentage (Internal message)But it seems to only present temp and hum as sensors and no voltage:
gw.present(CHILD_ID_TEMP,S_TEMP); gw.present(CHILD_ID_HUM,S_HUM);What is it i'm failing to understand? I just setup Domoticz and in there I have not yet got a good way of presenting historical battery levels, it just shows the latest internal battery level message. To get a better understanding on the battery life performance it is necessary to be able to create a graph. I thought I could use the voltage level for this but I can only see the internal message :-(
Thanks,

That's a leftover from my initial battery monitoring code. It could be re-implemented quite easily, in the battery reporting routine, you could report actual voltage measured, as an extra sensor
(I actually thought that I had removed everything related to the old monitoring code)
Edited
I have updated the sketch for sensebender micro, to include sending battery voltage measurements as a sensor value. This is not enabled by default though, and people need to recompile it, with a #define uncommented.
do a pull from mysensors github, to get the latest sourcecode

That's the old A10. It would probably work but A20 has some firmware fixes and more tests performed on it.
I have nothing to say about the price. It is the same as for A20.. As you can see it is the most expensive part on the micro board (30% of it's price).@hek said:

As you can see it is the most expensive part on the micro board (30% of it's price).Would you consider a Sensebender Micro Light-version without this component? i mean, if it's 30 % of the price, not available and not imo a critical component (you could always add your own humidity/temp sensors), there are quite a few reasons why a light version would be tempting. At least to me. :)

Well, it's a temperature sensor, and humidity in one :). If you are going to use other sensor types (DS1820, or cheaper humidity/temperature sensors), you also need to have a booster circuit, in order to boost battery voltage to 3V minimum (as they don't operate on voltages lower than that).
So in the end, you'll buy both booster circuits, and sensors, which will be close to the same price as the Si7021 in the end, to get the same functionality.
And since you (probably) are using a cheap booster circuit from ebay, the battery would not last that long, so you buy lot's of batteries to feed the booster circuitry :)
But when that's said, we could ask itead if they could make a "barebone" unit, without the Si7021 mounted, and then provide a quote on that type of sensor.

Thank you for your answer tbowmo - i see your logic.
But if you want to use it with say, light, motion or another sensor with this board - do I need a booster? -
Well, the atsha204 is only about 0.5$ in price, so the savings will be very little.
@sundberg84
If it's a pure motion sensor then I can see a point in using a light edition. I have requested a quote from itead on a light edition.
