For OTA Update under Rpi i used this: http://www.virtualhere.com/

• just install it on the Pi, stop the controler software

wget http://www.virtualhere.com/sites/default/files/usbserver/vhusbdarmpi2

vhusbdarmpi2 -> for Pi2 only (see homepage for other platforms)

sudo chmod +x ./vhusbdarmpi2

• start the virtualhere server

sudo ./vhusbdarmpi2

• install the client on your Windows System
• Mount the Com-Port
• start MYSControler
• do what you want to do
• stop client

now you have to reboot your rpi, stop virtualhere server its not enoth, cant mount device again. After restart everythinks works well.

Greetings

I will try it direct on the CR2032.

You are right, OTA not needed and not possible. The second Reed is for a second Window, i would trace it seperatly.
It's for a doble Window, the sensor is placed in the middle of booth windows.

Works like a charm! Thanks a lot!

@tonnerre33 Thanks, i solved it already, but you are right that was my Problem :-)

I am finished and everythink is working well right now.

I dit some modifications on PCB:

• add an 470uF near to NRF24
• add two Diodes recovery diode (or free-wheeling diode) dunno how it called in english :-) at the relays

And some changes in your example code :+1:

Thanks for the Layout, thanks for the code, thanks for help!

I design a 3D Case, but only the bottom side. . . but not tested right now . .

0_1478263225360_RollerShutter_back.stl
0_1478263256093_RollerShutter_Back.123dx

Works :+1:

Insert an delay between sends will help to refresh the load in the capacitor. I prefer to wait for 100ms before send a new message. And increase the capacitor. My Sensor (not battery) works fine until -15°C.

Me too please!

PS: can i send you a wishlist of features?

Dont Care :-) its cool. Zenner its not enoth but dont worry. I need it .. the nrf is verry "female" :-D (sensible). But i think for both version, you have to modify the current messurment. No Roller shutter has >200w so u are on the Limit below 100w of adc scale.

But hey it Works and your Layout is verry cool and Safe.
