HAM Bluetooth Card Switch

Bluetooth Hotel Card Switch For Energy Saving Without Extra Room Wiring

A smarter, easier-to-install alternative to traditional hotel key card switches.

The HAM Bluetooth Card Switch is a retrofit energy-saving solution for hotels, Airbnb properties, villas, and short-term rentals. It is installed directly in the electrical panel using the HAM DinSwitchM, without wall cutting, extra room wiring, or visible card holders.

Guests simply carry a small Bluetooth tag on their room keychain. When the tag is detected inside the room, the power supply is activated. When the tag is no longer detected, the system waits for a configurable delay and then switches off the room power to reduce unnecessary energy consumption.

Fast retrofit installation. No additional room wiring. Automatic energy saving.
