Secant Domotics replacement in a condo

The Challenge

We were contacted to replace an outdated domotic system based on Cardio Secant, a 10 years old installation, with the control screen damaged and not working.

The original devices were wired, including an alarm, movement, smoke and flood sensors. The flat was connected to a central water heater system and controlled via electrovalve. Blinds were motorized, but the actual system only allowed to operate all of them together (full up and down only).

Thanks to the customizable Open Smart Homes solution we were able to do the replacement WITHOUT MAJOR REWORK in the condo. All existing elements were reused on the new system. We also changed the existing Wifi devices to enhance the coverage and improve the actual communications inside the flat.

Customer Priorities

After initial study the following issues were prioritized:

  • Reuse all existing wired devices.
  • Replace existing funcionalities in the systems, alarm, sensors, blinds.
  • Improve blind controls.
  • Automate alarm arm and disarm.
  • Add existing smart devices, TV, vacuum cleaner..
  • Automate blinds to open and close them depending on weather and sun conditions.
  • Add manual buttons to operate the heating and water valves in case of issues with the system.
  • Prepare the system for future integrations.

    The new system

    To cover all the needs the following was installed:

  • Home Assistant server: House's brain, it was installed on the exisisting communications cabinet, to be able to fit a recabling and optimization was done.
  • Unifi Network devices: 2 APs, a router and POE switch were installed to enhance the wifi coverage.
  • Smart Wifi y Zigbee devices: Depending on the needs different devices were installed, also some custom ESP based devices were built to be able to integrate the existing blinds.
  • Existing sensors:All elements were integrated and all original functionalities were covered.
