About GreenGuest

In addition to guest facing features the app allows hotel staff to monitor energy usage and turn off the lights or A/C in unoccupied rooms after guest checkout. The app incentivises guests to conserve by providing bonus offers from the hotel upon checkout. Additionally the app utilizes gamification to inspire friendly competition among guests.

M2X Integration

In 2014 hotel electricity and water costs soared over $7.5 Billion. GreenGuest aims to reduce these costs and conserve energy and water with their innovative monitoring system and application. Once a guest checks in to a hotel they can view their consumption stats via the GreenGuest app, which is integrated with TripIt for easy hotel reservation discovery. GreenGuest is also integrated with Concur using the Concur API to facilitate rewards redemption in the form of expense credited back to the traveler.

Sensors that monitor water and electricity consumption within the hotel push data to M2X which enables real time display of consumption rates for guests and staff via the GreenGuest application.

The M2X Node.js client library enabled the developers of GreenGuest to quickly and easily collect and retrieve sensor data, which is at the heart of their product.
