Hi, I really appreciate if someone can help me with this question. I’m currently working with a Cerbo GX, it has 4 Digital Input Sensors which I plan to use to monitor the doors of a business. The problem is that I only have 4 Digital Inputs, but I need 10, the business has about 10 doors between the entrances and the office doors. I was looking in the catalog of devices for something that could give me the solution, but I couldn’t find anything.
What options do I have to add additional Digital Inputs to my Cerbo GX?
Another option would be to consider using z-wave or matter door sensors and home assistant… that would then allow you to have wireless connection between each door and the home assistant hub.
ex: TUO Contact Sensor with Matter Support – arre
It’s a very good idea, Thanks. but then I would have two systems in parallel, the Cerbo GX and the Home Assistant Hub. Is it possible to integrate a door sensor model via Bluetooth with the Cerbo GX?
That depends. Some reed switches are NC (normally closed), others are NO (normally open).
If you’re using traditional (wired) reed switches, you can monitor them with the Cerbo digital inputs. You’ll likely need to do some Node-Red programming to setup a notification system, or an limit alarm functionality based on the digital input may be possible via VRM.
I don’t know though how you would “arm” or “disarm” the system via Cerbo. It should be possible to build a custom NodeRed dashboard with a button to do this… overall, pretty clumsy. Home assistant does all this natively.
