I'm still experimenting and plan to post more details shortly. The monitoring prototype seems to be working well. Thanks for your interest in the project.
I am experimenting with a new prototype, more like the one originally proposed that would allow monitoring as well as control of an alarm panel. I've found an easier way to interface and will post some details once I've had a chance to text it out.
Thanks! Would you still recommend the same hardware components? I'm going to start sourcing stuff if so. This'll be my first arduino foray. I have a few rpi's and developed middleware in java/.net for 15 years, but I'm a little weak on the hardware side.
I've been happy with the monitoring prototype - schematic shown under Dec 22, 2021. This used one onto-isolator and one resistor: SparkFun Opto-isolator Breakout (https://www.sparkfun.com/products/9118)
I'm now experimenting with being able to send and receive using: SparkFun Logic Level Converter - Bi-Directional (https://www.sparkfun.com/products/12009)
If you're going to get one of the SparkFun devices, go ahead and get a few of each, they're pretty cheap. I've been happy with the Arduino MKR 1010. It has the ability to import an SSL certificate so you can have secure communication to your backend, which was important to me. It also had a lot of flexibility with RX/TX ports, allowing use of 2. I'm still up in the air about WiFi vs. wired ethernet. I did get a couple cheap LAN modules which I might try connecting to see if they are any more reliable than WiFi.
Sounds good - I'll start with those. I am liking the "monitoring only" option. I am bringing over a lot of smarthome devices from the last house and finding that my consumer gear is oversatured with 100 devices on the network - about half are wifi. I am looking to go ethernet if possible as it has proven to be reliable on my present network. I'm not too concerned with security locally as I keep my smarthome IOT isolated, and will likely vlan this into it's own as well. I appreciate the advice, I'll start sourcing and then send some pictures too.
Still running strong? I'm going to try to follow your lead and use this. I have a 32zone system that works great, but need to plug it into HomeAssistant. Thanks for posting your work!
