sundberg84. Thanks for the advice. The LEDs are not always a good source since they stay on after the first trigger. I was able to tap into the buzzer using an optocoupler/optoisolator.

I used a simple button sketch and can get LEDs to blink on the input and output side of the optocoupler (all hardware, no software involved), as well as an LED controlled by the arduino based on input from optocoupler.

The struggle I am having is getting a mysensors sketch to adopt to the gateway with this setup. I have other door switch and temp sensors in the system no problem with homeassistant.

I have used the basic door/binary/button sketch with no luck. My gateway's LEDs indicate that the signal is coming through but it won't adopt.

I have also tried the fire alarm sketches linked below but they will not compile even after fixing the library issue.

Looking for ideas. I will try to post a video of my wiring and what is going on as soon as possible. I think I am just missing something simple.

Thanks!

@mfalkvidd the image is based on resin.io. I will do some more digging but your advice might be the best option. I really appreciate your help on this. I will report back what I find. Thanks!

sudo modprobe ch341
modprobe: FATAL: Module ch341 not found in directory /lib/modules/4.8.17-yocto-standard

Must be a package I need to install? I just used the standard hass.io image for the NUC.

Thanks for your help on this!

@mfalkvidd Thanks for the tips. Still trying to figure it out.

[631437.779324] usb 1-3: new full-speed USB device number 6 using xhci_hcd

I have tried different combinations using device 6 and it still is not validating my config file. Any ideas?

Tried
device: '/dev/ttyUSB6'
device: '/dev/ttyACM6'
device: '/dev/tty1a86:7523'

Thanks!

Hello,

I recently switched from a raspi to an intel nuc. My serial gateway worked well with the raspi. I am struggling to figure out the config parameters for my nuc. After a lot of google searching, I can't find it but am probably missing something easy.

Below is the default. I cannot find the right terminal command for the nuc to show the connected devices. Any ideas? Thanks!

device: '/dev/ttyUSB0'

@jocke4u could you share some more information on your power sensors? Pictures and sketch? I am trying to replace my ubiquiti mfi setup and power sensors are my last sensors to go. Thanks!

Great project! I could use some help getting this to work. I am using the newbie PCB, just a regular RGB LED for testing and Homeassistant as my controller. Hass adopts the node but I get this error message everytime I restart the node and the switch does not appear on my frontend.

"Not a valid message: Not valid message sub-type: 40 for dictionary value @ data['sub_type']"

I am running '2.0' in my hass config file. I have tried '2.1.' and '2.1.1' with no success. Homeassistant version .60.

I have several temperature sensor nodes talking to hass just fine. Any ideas? I assume I am just missing something simple as I am relatively new to homeassistant and mysensors.

Thank you in advance for your help!

@Nca78 That kind of worked. It downloaded the STL file as a .bin file. Had to manually change the extension from .bin to .stl. It loaded but it is just the base part and does not include the main enclosure. Thanks! Chris

@barduino Awesome project! The links for downloading the files are not functional anymore. Can you repost?

Thanks!
