I recently installed an eyezon uno panel for my parents to replace their old DSC system. Only issue is 1/2 keypads arent compatible with the panel. There are compatible panels but they cost $150+, so alternative is to use an ESP32 with a screen and link it via home assistant.
Whats the best budget friendly touchscreen i could buy thats solid enough to activate/deactive an alarm system (keypad + arming status)
