[RELEASE] Konnected Security 2.0 - Connect Wired Alarm System Sensors and Siren to SmartThings - big update and new name!

Pre-orders from our Konnected store have shipped! Thank you all for your support!

I just got back from the post office dropping off most of the “Konnected Security 2.0” NodeMCU-based kits that you all pre-ordered from our store (a few are going out tomorrow). Exciting day! If you pre-ordered your kit or placed an order over the weekend, you should have your kit within a few days (if you’re in the U.S.). You will not be disappointed!

All of these kits are pre-loaded with Konnected Security 2.0. Just follow the setup documentation here to wire your sensors and set up the device. The documentation is still a work in progress, and I will be adding a lot more detail to these pages over the next week.

I still have some inventory ready to go from my initial order, and more are on the way from China, so if you were thinking of trying out this project, now’s a great time to place an order :wink:

@copyninja and I have a ton of great ideas for improvements, new features, and new/related products, so please continue to provide feedback, especially if you’ve tried the 2.0 release. I’m taking some time off in-between “real jobs” right now to focus full-time on this project! With your support, maybe, just maybe, we could make this a full-time venture with the goal of making low-cost, open-source home automation hardware accessible to all. If you’re excited about this vision, please consider donating to keep this momentum going!

Thanks again to this great community for making this happen!


Thanks for the update.
i spoke to a brother of mine about your work and he is also interested, i here today that he has spoken to a couple of friends and they too… so word is getting around in the UK. i personally can not wait…and will keep you posted on my install. Thanks a lot for your hard work and good luck to you both, well done.

@Nhaley if you have an extra board, set it up first with the 2.0 software and you can test opening and closing the door by just connecting and disconnecting a wire directly from pin DX to GND. You’ll see duplicate devices in ST for each sensor once you set up the new board. Then when you’re happy with the new setup, just swap out the boards in your alarm panel. Finally, delete the old devices from smartthings.

Thanks Nate, sounds nearly seemless!

Sorry if this is a silly question, but in the photo in original post, why are there so many wires still connected to the alarm panel? Other than TX, control panel and power, what is there? Or is the system partially switched over?

The power is still running through the alarm panel, which in most cases outputs 12V DC. If you have an existing alarm panel, you can easily draw power from it to power the NodeMCU. The wires on the left side of the alarm panel contacts are mostly for power out. My siren, motion sensors and glass-break sensors are still powered through the alarm panel, but the sensor/trigger wire has been moved over to the NodeMCU.

The wires on the right side of the alarm panel are for the analog phone line. I just never disconnected them, just lazy. It doesn’t do anything … I don’t even have landline phone service.

If you want to completely remove your old alarm panel for the “cleanest” installation, you can totally do that. In that case, you should power the NodeMCU device with a 12V DC power adapter and you can use it to send power to the motion detectors, siren and other powered sensors throughout the house.

See here for more detail on power:

Yea i think the only problem is where those wires come down, I wouldn’t know which is which. Its wired for window/door sensors, smoke detectors, motion etc…


The easiest way to figure out what door or window each wire belongs to is to use a “wire toner/tracer” device like the following

I configured version 2.0 yesterday. I do have to say that I’m quite happy so far. Automation involving my contact/motion sensors seems to be way more responsive than with v.1. Great job, guys!


Since i dont have an existing panel how would I know how many “zones” i have? I would like to purchase the kit but im not sure which one I would need size wise.

How many wires are coming out of the wall? That is basically the maximum number of zones. This can be reduced if you wire some of the magnetic sensors together in series (at the alarm panel location) to truly create a “zone”. A zone is just a grouping of sensors that are wired in series. A zone can have as few as one sensor or as many as you’d like to combine. The downside of creating zones with many sensors is you do not know which one triggered. So, people typically combine all of the window sensors from a room to create a “zone”. Then at least you know which room tripped the alarm.

Awesome! Thanks for the info! Makes sense. I should have looked at the forums first. I just bought like 180.00 in zigbee open/close sensors for the all the windows, mounted them, and got rid of the boxes…

Is there anyone else that isn’t seeing the device on WiFi during initial setup? I had version 1 (pre-Konnected) installed on the board, but flashed konnected-security-2-0.bin. Thinking that the old files might stilll be there, I did a Format via Esplorer, and sent the firmware again. Still, I’m not seeing the device broadcasting on WiFi.

Did you upload all the files from the source-code directory?

Nope. :confused: I had done that with the prior version, but wasn’t sure if that was required with 2.0. Thank you!

Edit: Working now. The GitHub integration is very cool btw. Glad that you named it properly as well. :stuck_out_tongue: Almost all of the ones I have setup are named “SmartThingsPublic”.

Yes, you need to upload all the files in the source-code directory before wifi setup will work.

I think because you migrated from that pre-konnected, your Wifi SSID was saved in your NodeMCU device. Your device should automatically connect to your WiFi. Try checking your router to confirm.

You can proceed with running the SmartApp http://docs.konnected.io/security-alarm-system/setup/discovery/

Let me know if it works.

The WiFi settings were preserved, even though I had clicked on the format button in Esplorer and received a message that it was successful. It connects to WiFi very quickly!

One question, the app shows that 7 pins are configurable. Were you able to get a 7th pin working?

Thanks for all of your help. Nice to see that the documentation is building up. I imagine that some YouTube videos would be popular. FYI: the link for Windows drivers is 404.

The 7th pin is D8 which is only usable as an output (for a siren), not a sensor. I also have seen some issues with D8 triggering the siren upon reboot or power failure, so I’m not really recommending using it right now, although you’re welcome to try. I need to do some more experimentation on this and will update the docs.

Youtube videos are on the roadmap :wink:. There’s a lot of work to do!

Cool. I saw pin RX in there, I’ll be using that instead. No plans on a siren for now. Great job by both of you.
