Running in ~300 hotels since 2005
TES builds the control systems behind guest rooms — power, access and air conditioning — from the embedded module in the wall to the dashboard your operations team watches. Whole-building systems and single-unit modules, one engineering team, no black boxes.
Product lines
PACsys governs electrical state and the guest lifecycle. TCMsys governs air conditioning. Tnode and Knode bring the same control down to a single indoor unit. Each deploys independently and shares the same operational philosophy.
Power & access control
Property-wide control of guest-room electrical state — lights, AC, common-area fixtures — tied to the check-in and housekeeping cycle. PACsys Network puts every property you operate on one screen.
Centralised AC control
Centralised control of every air-conditioning unit on a site — AC and non-AC rooms alike, across mixed manufacturers on one wired bus, driven by the TCM Module in each room.
Mitsubishi AC control modules
The same engineering on a single indoor unit. Tnode puts a commercial unit on your phone; Knode gives a guest room keycard-driven control without a site-wide system.
What we do
When the bus misbehaves at three in the morning, the person who wrote the protocol works here. That is the whole argument for building it all ourselves.
Floor controllers, room modules and segment gateways designed in-house — PCB, firmware and the RS-485 bus protocol they speak. We own the stack from the copper up.
Dashboards, REST APIs and reporting that run on the property. On-premises, cloud, or hybrid — the controllers keep working either way.
Check-in, check-out and room moves arrive straight from the front desk. Guest-facing state follows the booking without anyone retyping it.
Field engineers diagnose a bus fault from their phone — port discovery, device sweep, live frames. Most issues resolve without a site visit.
Occupancy-driven setback, per-room power monitoring and the reporting to prove the savings to a finance director.
One dashboard across every property you operate. Version rollouts, device health and audit history without logging into each site.
Why operators choose us
Generic IoT platforms model devices. We model rooms, guests, floors and fixtures — because that is what the front desk, housekeeping and the maintenance supervisor think in.
