Contact sensors over LAN?

🛎️ Get Help
1

My home was pre-wired with all door sensors to a closet with no alarm installed. It also has a ethernet run to my switch. Is there device that will show these 5 contact sensors via the LAN connection?

I see Konnected has a LAN device coming out next year, but are there any other options?

You could use HubDuino to connect the contact sensor to a esp8266 unit or so and then connect that unit to Hubitat. Take a look here:

It sounds like a perfect application for Konnected.io - I don't understand why that wouldn't work . . .

I understood the current devices were WiFi only.

You can use a Arduino with a Ethernet shield.

If you don't want to do WiFi, I guess you'll have to wait. Did they say when they will start shipping the wired ethernet version? That seems like a very minor change . . .

The existing konnected boards are wifi only. The new pro board is 12 zone and lan capable though. Should be out 1Q2020.

As another option you can get arduino lan connected devices today, though. I just replaced my three konnected wifi boards with a single arduino mega connected via ethernet, which comes into Hubitat via hubduino.

Arduino mega with an ethernet shield runs <$50 all in. You may want to also consider installing diodes on the inputs, though, to give a little lightning/electrical rejection. They are like 100 for $5 though, so not a big deal.

Great suggestions everyone. I appreciate the help.

I just finished setting up Hubduino on a Ardruino Uno, ethernet shield, and a I/O Shield. Looks like it will work great !!
