Are there any adaptors for existing wired burglar alarm to HA?

Is there any sort of adaptor that would replace the control box of a burglar alarm? Until a few months ago my workshop was protected by a wired burglar alarm system (Pyronix I think) but the main box died of old age. All of the sensors are wired and some need a permanent dc supply.

While I could kludge something up with IO pins on the Raspberry Pi, this must be quite a common requirement and it would seem to be a bit of re-inventing the wheel to make something if a well-researched and properly made device exists to adapt the existing sensors to a home automation system.

For scale, my existing system had 4 door/window sensors, 2 PIR motion sensors, and 1 wired smoke alarm. All of the sensors were wired back to the panel, not on a loop as that was the easy way to do it.

Have a look at Konnected.
You can either do it yourself on a ESP8266 board and connect the zones to it etc.
Or you can buy the ready made boards they do.

Thank you Steveuk, that looks like it will do what I want. I will see if I can download their manuals to find out how I want to implement it. Zigbee preferred, but wired to the Pi is also an option. :sunglasses:

If you’re going to try Konnected it’s all connected through WiFi then you can use MQTT.
If you’re wanting ZigBee you could look at finding a ZigBee relay, or even some door contact sensors like certain fibaros have external connectors where you can wire the door contacts to.

i use cheap zigbee door sensors.
open it , put two wires on the magnetic component
sure to achieve this you can do this with wifi,zigbee-rf-z-wave or others protocols sensors too

The intention is to avoid using batteries in the system and to not have energetic RF noise - Zigbee is O.K., but WiFi is too noisy. I did find Konnected and they offer the “Konnected Alarm Panel Pro 12-Zone Smart Wired Alarm Kit” but this would be about £250 with taxes and shipping. I also found an affordable device on eBay “Home Burglar Alarm to Smart Alarm Conversion Kit” but the signal connection to the network is WiFi.

I suspect that the only practical option is to hardwire into the Raspberry Pi but as this also has the touch screen dashboard it would be a shame not to be able to relocate when and as needed.

So going off that it looks like you’re in the UK.
In that case you could do exactly what I’m doing.
I bought a Honeywell Flex 20 off eBay used a few years ago now for about £50 and that’s connected to my wired motion sensors.
That panel allows add on modules and I’ve added 3 modules so far
1.Ethernet module for internet connection.
2. RF wireless module so now I’ve added RF contacts sensors to the areas that are hard to wire to
3. And another module developed by “Selfmon” which then makes the connection between the alarm panel and my home assistant but using MQTT.
But selfmon also does a monitoring service for about £1 a month that will alert you of a intruder by text, email phone call etc.
