This integration is being included in my submission to Shelly’s Smart Home Challenge 2025.
Home Assistant / IQ 4 / ADC Integration
This article is the ‘home page’ for my entry in Shelly’s Smart Home Challenge 2025.
The overall solution allows for the following features, and uses a number of Shelly components. Since there are multiple components and scenarios, links to each of the three integrations and their setup guides, including a demo video and other information are included below.
Project Description
This project utilzes a number of Shelly products to act as a wired integration between a IQ 4 Alarm System panel (and thereby alarm.com) and Home Assistant. This same type of integration can be accomplished using a number of alarm systems and home automation platforms with the same basic principles, making this an excellent ‘soup starter’ for other ideas and integrations.
Specifically this integrates the IQ/ADC Alarm System to Home Assistant with the following features:
- Send ARM and DISARM state to Home Assistant
- Send ALARM state to Home Assistant (is there an active alarm event)
- Trigger ARMING and DISARMING from Home Assistant
- Trigger IQ/Alarm.com scenes from Home Assistant
Demo and Overview Video
Components Utilized
- On the Alarm System side:
- IQ 4 Alarm Panel
- IQ Hardwire 16
- Shelly Wave i4DC
- Shelly Wave 1
- On the Home Assistant Side:
- Shelly 1 gen 4 (Zigbee mode)
- Shelly 1 gen 4 (Zigbee mode)
- Shelly Wave i4DC
- For the light and scene demonstrations:
- Shelly Wave 1PM (connected to IQ/ADC and led bulb)
- Zooz ZEN72 Dimmer (connected to IQ/ADC and led bulb)
- Sengled Zigbee RGB Bulb (connected to HA)
- Third Reality Remote Button (Zigbee connected to HA)
Design Standards
For this set of integrations we established the following standards for consistency and ease of integration:
- Must be all 12v DC to be driven off of common power (for eventual installation in a project box or equipment enclosure)
- Uses Zwave and IQ Hardware (or various IQ compatible wireless sensors) for the IQ side
- Uses Zigbee and/or z-wave devices for the Home Assistant Side
Why Shelly?
Shelly components allowed for the use of low voltage (12v in my case) which makes for easy inclusion of components inside existing alarm system equipment cabinets. In addition, some panels have available 12v that can be leveraged so there is no need for additional power supplies (load permitting, of course), and it can run with the same battery protection as the panel.
The ability for Shelly to operate in zwave, zigbee, wifi and bluetooth gives great flexibility to the end-user. While this example is zwave and zigbee, on the HA side it could have been done a number of ways.
Shelly components are also very small in size and easy to accommodate a number of relays in a small physical space.
