Dear all,
please see the instructions at https://www.verdrahtet.info/2019/01/04/homematic-statusanzeige-selbst-genaut/
Thanks to Stefan for this project.
There will be some options:
- with switch / without switch (already here)
- version with Micro-USB Plug (as soon i got it from China ;-) )
- version with Li-Ion Battery (later on...)
I tested the display with a power supply of 3 AA Battery (see the picture), but this will work only a few days, even if you desolder the LED on the I2C controller.
For the power supply just drill a hole in the housing wherever you need it.
Please see instructions.
Have fun!
Notes:
No supports for the Display-Cover!!!!
Post-Printing =============
Instructions
You will need the following:
2-4 Screws M2.5*6mm
Microswitch 5*5mm
You should to remove the LED on the I2C Interface, cause this is useless.
Remove the jumper from the pins at the I2C interface and connect the switch.
If you want to decrease the brightness of the LCD Backlight, use a resistor.
File a small notch on the LCD platine to guide the cables for the switch to the front.
Then fix the switch with some hot glue in his position.
That's it!
