Hello from my side! Look for modular pieces with clear installation and reset procedures. INDESTROOM produces escape room items https://erworkshop.com/escapes/puzzles-and-props/ such as sensor-based triggers, electronic locks, hidden compartments, sound or light gadgets, and themed objects with puzzle logic. Give them your controller details, available power, opening sizes, wall materials, theme, and the time you can take the room offline. You should ask which work can be prepared in advance, whether the prop arrives programmed, how many puzzle actions it contains, and what staff must test after fitting.
