Could you give me the size when the pcb is fully soldered as battery sensor?

I'm trying to use the serial monitor but I'm always ask entering a password? Although I didn't used one?

Reflashing sketch via OTA worked without any issues.

Edit: Tried to use a real OTA password and it's still not working although I'm using the correct. ESP8266 Tools 2.2.0

In some countries there are limitations That may be a reason. I tried to document it a little bit in the dev branch: https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/MyConfig.h

Seattle (https://www.linkedin.com/in/jcoliz // https://github.com/maniacbug) and Newport Hills Park (https://issuu.com/cascadebicycleclub/docs/courier03_15_r9) are in a really near distance to each other. So it could be his Linkedin account

Sadly I can't change the pins as easy as I want because I'm using a PCB. I'm trying to use:
D4 = ERROR
D7 = TX
D9 = RX

Using D7 for TX is working properly, only if I'm changing the other values. The gateway isn't working anymore.

I just tried to compile a GatewaySerial (Developmen branch) (https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/GatewaySerial/GatewaySerial.ino) with MY_WITH_LEDS_BLINKING_INVERSE enabled. It compiles but the Gateway can't receive any data, uncommenting this line and recompiling solve this issues. So it must be this function.

Thank you.

@meddie What's preventing anyone from walking up to your window and feeling if it is locked or not?
Or look at it this way:
1 = open, 0 = locked. If sent in clear text, an eavesdropper sees '1' or '0'. Now, assuming he knows which is what, then he knows the window is opened or closed. But that is really not important information.
So what do you get by encrypting that data? Well, you achieve "some certainty" that an eavesdropper don't know if you just locked your window. But he will know for sure you did something with the window at that point in time. And there is a 50% chance, you locked the window.
Now, that being said; encryption is supported for both NRF24 and RFM69 radios, so if it makes you feel better, just enable it. It won't makes things worse. But signing provides a far greater security value than encryption, so if you really care about security, you should prioritize signing.

Maybe it's my bad English or I really haven't understood it correctly.

Signing: Verifies the sender and receiver are known.
Encryption: Encodes the message so it's only readable for you.

So in conclusion, if I'm signing my messages I'm only getting my messages and only I am able to read my messages. So no third party can give me wrong messages and can't read my messages? He also should not be able to read if I'm playing with my door/window nore if I'm opening or closing it.

Interesting found indeed. I've send a pm to the user this could belong to. Maybe you could remove the link?

Thats right. But with the same principle you can also read an external voltage that is fed into the Aref-pin. Just read the value of the internal 1.1V reference against the external reference.
Sadly the Aref is not available on the pro mini boards. With some soldering skills it could be obtained directly from the chip.

I'm not 100% sure, but I guess it should work for Pro Minis, too? I'm going to give it a try and maybe implement it, to MySensors Dev...

Could you link your sketch and post your FHEM entries?

@Heinz very nice work (wie heisst du im FHEM Forum?)

Does someone have the values a MQ-07 needs to perform properly? I rally don't know how to gather the right values from the description....

Thank you

Hi Alex,

I just have had a short contact on github with you and on the FHEM forum.

I followed this project on your homepage and I'm very interested in it. Great work.

Just a few question:
You are using a 10uf capacitor, although only a 4,7uf is recommended: http://www.mysensors.org/build/connect_radio ?

Do you have sources there to buy (shipping to Germany) the different pieces to build up your sensor? And is it possible to buy a whole pcb (maybe ready to use )

Thanks Matthias
