Good guys to deal with
Good guys to deal with that care about what they do. Also glad someone has put the effort in to design and manufacture such products. The PRO is quite unique and it does the job well. Wish them all the best of success.
Good DIY, bad if experienced
This is a decent device but it lacks some simple features that it SHOULD have. ALL alarm panels should have end of line resistors for device verification. There's no built of function to reset resetable devices. The panel requires you to use two apps. Relying on an additional app to make use of the alarm is just lazy.
Our house has all of the windows and doors on the main floor wired up, now I wanted to integrate then with Home Assistant. So far I've just installed a few sensors, but they work well. The integration with Home Assistant was very easy and fast.
