MSR-2 + Alarmo home security install

My grandmother wanted a security system that would alert her when there was movement in her home after she had gone to bed. So, I set up three of our Apollo Automation mmWave sensors. These devices, plus the Alarmo integration, quickly allowed me to install a fully local, private, cloud-free, and no monthly subscription security system. She can arm/disarm it with one button on her Home Assistant dashboard, and it makes her feel much safer. This guide assumes you already have a motion/presence sensor installed on HA.

1. Install HACS
2. Install Alarmo and the Alarmo Card (Pretty Arm and Disarm card for your HA dashboard)

The first button opens Alarmo in HACS and the second opens the Alarmo Card:

Restart Home Assistant once both are installed, then add the Alarmo integration under Settings → Devices & services → Add integration. Alarmo shows up in the sidebar after that.

3. Find Alarmo on the left, select the Sensors tab, and toggle on the sensor entities that you would like to use for your alarm system.

Shown with MSR-1 sensors; add your MSR-2 radar target entities the same way.

4. Now select the Actions tab and under Condition > Event > Select "Alarm is triggered". You can also select the device you would like to receive a notification on under Task > Target > Select Device (Phone, tablet, etc.)

5. You can change the Title, Message, and Name of the alarm notification.

6. After saving that action we can add another one that will turn on our sensor lights and/or make the onboard piezo buzzers play an alarm sound. Under Entity select your sensors RGB light.

Shown with AIR-1 and MSR-1 lights; pick your MSR-2 RGB light the same way.

7. Under Action select Turn On and now your sensors RGB lights will turn on when the alarm is triggered.

Shown with AIR-1 and MSR-1 lights; the MSR-2 steps are the same.

8. And that's it, seriously... Now you can enjoy a free and local security system.
