Konnected Alarm Panel Pro 12-Zone Conversion Kit

D2 Cloud-Optional — Full function with the router off.

The unplug test

The panel keeps reading every wired zone and driving sirens, strobes, and relay outputs exactly as before, because that logic runs on the board's own ESP32 and whatever local hub (Home Assistant, Hubitat) it is paired to. What stops working is anything routed through Konnected Cloud: the SmartThings/Alexa bridge integration and the remote firmware-customization service. If it was set up and is being run through Home Assistant or ESPHome rather than the Konnected app's cloud features, disconnecting the router changes nothing you would notice.

Why this tier: Konnected operates a named optional cloud service (Konnected Cloud) that bridges the panel to Alexa/SmartThings and offers a firmware-customization service, but Konnected's own support documentation states plainly that 'all Konnected devices work fully without Konnected Cloud, giving you complete local control,' and the core function (reading wired alarm zones, driving sirens/strobes/switches) runs on the board itself over its documented Home Assistant, Hubitat, ESPHome, and Matter integrations. Wi-Fi credentialing can be done from a local browser via the device's own captive portal (192.168.4.1) with no app; a Konnected account is only required to reach Konnected Cloud, not to provision the board or use it through a self-hosted smart-home platform.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
