this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....

Ok, finally I found the Problem. I changed the prescaler value of Timer0 becuase I needed a higher PWM Frequenciy. Unfortuneatly this also affects the millis() function that is used in gw.wait. It turns out taht with the changed TImer 0 Prescaler 1ms was not 1ms anymore but less. So the gw.wait(750) where only 750ms/64 which is not enough for DS18S20 conversion to take place.

@GertSanders ok, strange. standard pin headers fit for me only into FTDI and ICSP pin holes. Into the other two 8 pin rows it does not fit.

Hi @aramko-aramko. Unfortunately, this model is already sold. You can look at the upgraded version of this device - MDMSNode "Lighting" Rev 1.1.

I'm wondering what the minimum input voltage is. The description only says max. 6.5V input voltage from the battery, but does not say what the minimum is. Both the nrf24l01+ as well as the atmega328P work with 3.3V, so if I use three AA batteries, that should be fine, right? I suppose using two AA batteries is not enough?

@martinhjelmare Wow thank you so much. I've cleared the eeprom and now it gets node id 1. After removing the persistence file the sensor now shows on the web interface.

I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them. https://github.com/giltesa/SmartHome

@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.
