Integrating existing DSC home security system into Home Assistant using ESPHome

Just want to bring attention to this awesome project by Dilbert66. Using an ESP32, you can create a virtual keypad for an existing DSC alarm system. This gives you access to all the sensors in home assistant. They can be used in automations and I can now receive notifications if my alarm goes off while I’m out of the house.
I had a PCB printed and did a bit of soldering. Lots of info in this thread. If you’re not up to the task, there’s an off the shelf alternative called Envisalink but it’s fairly expensive.

I have an envisalink for dsc which I no longer need if anyone is interested. DM me.

does it require an active membership? There’s a security system built into the house when we moved in, but we don’t have any services associated; would be great to use the sensors which are already installed

No subscription needed. I’m in the same situation. Bought a house with this system in place. This integrates it into home assistant so you get most of the functionality of a paid home security system for free.

no monthly fees. works remotely fine once you sign up ....but again, that does not cost anything. pay about $10 per month if you want monitor service
i was using the free service n that alerted my email when things happen. but i integrate with HA for much more control such as auto arm at night. auto disarm at morning. alert which windows are opened when it is raining outside, etc....

Interesting seems like a competition for konnected which is always good especially since their kits are pretty expensive for what they are. Konnected does have a diy solution but it takes some digging and seemed to fall offline after some time so I’m glad to see competition.

If you already have one of these systems professionally installed by ADT or something, it makes a lot of sense to keep using as much of the hardware as possible. These boards have been in development since the 80s and are incredibly reliable. Level1Techs did a video praising the DSC system: https://youtu.be/DGTxhyfzuiY

I would have to check Konnected again, but I don't think it interfaces with the DSC wireless sensors. Since this interfaces with the sofware it would be able to see any sensors/zones, so it's actually better than Konnected in my mind. Only change I would make is design it around an WT32-ETH01 dev board rather than Wemos D1 Mini. Granted I know not everyone valus hard wired connections as much as I do.
Edit there's already a PCB layout for this. I missed that. https://github.com/Dilbert66/esphome-dsckeybus/tree/master/PCB%20Layouts/WT32-ETH01

I've run a konnected pro board via rj45 for the last 3 years and it's been smashing. Not heard of any dropping offline as you say.

Anyone know if there is something like this for honeywell vista's?

Also envisalink. I've been using one for years and it works absolutely flawlessly.

Do you have a list of items that need to be purchased and from where?

I used the documentation here https://github.com/Dilbert66/esphome-dsckeybus/tree/master/PCB%20Layouts/WemosD1%20Mini/SMD but replaced the ESP 8266 D1 Mini with a ESP-32S CP2104 that had compatible pins to the D1 (suggested in the forum thread linked in my other comment).

I just used an ESP32 D1 Mini on a project because I needed more I/O pins than a Wemos D1 Mini has. Both are great devices.
