Home-Assistant-Mail-And-Packages VS alarmo

They're probably using the Mail & Packages integration for Home Assistant.

It works via email. You sign up for emails from USPS and it parses email every day to see what mail will be delivered. More details here

I just did this with our ancient system. I replaced the keypads with Ring Alarm Keypads v2 which connected to my Home Assistant server via Zwave and stay in sync with the Alarmo custom integration using this Blueprint. It all works great and was much easier than expected to switch over.

If you have an existing Ring security system, you can either integrate all of it's sensors and alarm control with Home Assistant via Ring MQTT or get your own ZWave hub, connect all the sensors to that, and use Alarmo to create your own security system. I'm doing the former since I want to pay for the peace of mind that comes from a professionally monitored security system, but can switch to the latter if Amazon gets too greedy.

Never before heard of Alarmo.

As others have mentioned, you can replace the ADT mainboard with Konnected. From there, expose your now Konnected hardwired sensors to Home Assistant and setup an alarm system using the Alarmo integration. Expose that all to HomeKit.

I had a hardwired security system in the house I purchased and I replaced the main panel/board with Konnected Alarm Panel Pro. All of the existing hardwired sensors (doors, windows, motion and siren) are then integrated with Home Assistant. I use Alarmo, an alarm integration for Home Assistant, to create an alarm system which is then exposed to HomeKit, also via Home Assistant.

another option, depending on your use case, is to replace the alarm entirely with an open source solution. Alarmo for the software side, and Konnected.io for the replacement alarm board are the first things that come to mind.

As a side note, Home Assistant also runs my home security system as well. I used the Konnected Alarm Panel Pro to re-use existing hardwired sensors from an older security system that was already in place. I then used the Alarmo integration for Home Assistant which basically makes setting up an alarm system a breeze.
