paradox-esphome's Introduction

Paradox-ESPHome

Connect Paradox COMBUS (green-yellow wires which connect alarm system to the keypad) alarm interface to Home Assistant using esp8266 device and ESPHome library.

Currently the implementation is read-only, it shows motion, window/door, smoke sensor and alarm state status in Home Assistant (with a slight delay).

Example in Home Assistant

Wiring

Because Combus operates at ~12v, we need to step down voltage to levels suitable for esp2866.

Wiring example:

  Alarm Aux(+) --- Voltage regulator (5v for Wemos, NodeMCU, 3.3V for generic esp8266) --- VIN pin on esp8266

  Alarm Aux(-) --- esp8266 Ground

                                       +--- clock pin (Wemos, NodeMCU: D1, D2, D8)
  Alarm Yellow --- 15k ohm resistor ---|
                                       +--- 10k ohm resistor --- Ground

                                       +--- data read pin (Wemos, NodeMCU: D1, D2, D8)
  Alarm Green ---- 15k ohm resistor ---|
                                       +--- 10k ohm resistor --- Ground

When using different pins, be sure to modify sources to match your configuration.

OTA updates

In order to make OTA updates, connection switch in frontend must be switched to OFF.

Compatibility

Tested with "Trikdis SP231" alarm system which uses Paradox-compatible green-yellow data bus (COMBUS). Should work with other Paradox alarm systems.

References

Suggestions

This is a rough implementation, stability is not guaranteed. If you want a stable solution with read/write capability and your alarm system is compatible, take a look at Paradox Alarm Interface, which connects to alarm system by using serial port. In my case my alarm system was not compatible and had to use my own solution.

Do you have any idea what I'm doing wrong?

NodeMCU blinks fast when CLK pin is connected.

Hi there, I am trying to connect a NodeMCU running the code on my Paradox alarm system. I followed the diagram (As far as I know) and as soon as I connect the CLK (Yellow wire) to the pin, the blue light starts flashing quickly and then it disconnect. It won't event connect is restarted with the pin connected, but if I start it without connecting the pin just to test, I see it, but then as soon as the pin gets connected it crashes.

I am not that familiar with that type of development so I might be missing something stupid as to how I should troubleshoot this. When looking at references you used for your development, I saw that they were using 33k ohm resistor instead of 15k. I tried and has the same problem. How could I troubleshoot the startup of the NodeMCU?

Is this a behavior you have seen while developing on your side? I tried changing pin and had the same problem with D1, D2 and D8. If I don't call 'attachInterrupt' on the pin it doesn't fail, but as long as I change the code to point to that pin, and connect the CLK it fails.

Thanks for any support you can provide!

Wemo D1 mini

Not an issue, rather a request for help (the discussion section is unfortunately not available).

Thanks for your work on connecting Paradox alarm panels to HomeAssistant.

I'm planning to connect unidirectionally my old Paradox Spectra 1728EX panel to HomeAssistant and your work and repo gave me a hope that it can be done.
I'm planning to connect it via Wemo D1 mini that supports I2C and SPI modes [1]. Looking at your wiring diagram, since your diagram uses only a clock and a data pin I suppose it's I2C. Could you please confirm?
Since I plan to power the Wemo D1 mini from an USB adapter I presume that the Alarm Aux +/- connections are not needed. Neither the voltage regulator. Am I right?

Thanks in advance.

Question only about Combus

By Combus do you mean the yellow and green wires?

I have a trikdis SP3 panel now and am really interested in trying to integrate this with home assistant.

My panel has a 5v output, possibly an extra combus output on the side of the 5v. I'd have to check as I don't recall off the top of my head.

I notice there is no discussion option on this repo.

Many thanks

Just looked at the pdf and it has a 485 output for the RS485 data bus. Can these be used for the esp32?
Plus these:

+5 V Positive 5 V power terminal for 1-Wire devices
1 WIRE 1-Wire data bus terminal
C Common negative terminal
