Their 'Flat' and 'TMD' switches offer customizable designs to match any application.  You can also add your own background, logo or icons using Zennio's online tool and finish off the walls of a house or hotel with something uniquely designed for that building that is bound to impress.

The Zennio approach of including standard functional blocks in their devices (eg. brightness controllers, thermostats) that are common across all the devices is very helpful and makes configuration easier. Zennio logic blocks are incorporated into many devices are very useful for that little bit of in-project logic where you need it.

Especially Useful Products

Energy and Water Metering

The KEM input module has inputs for split-core transformers to measure current as well as water flow and temperature. 

Current measurement allows the module to return instantaneous and historical energy usage values, including CO2 usage and costs based on entered tariffs. This allows for graphing in management and visualisation software, and energy management of (for example) solar installations.

Water temperature readings can be used to determine underfloor heating flow and return temperatures.

Water flow measurement can be used to measure water usage over time or to provide an alert of a water leak if there is a sudden change in water use when the house is unoccupied.

Flexible Input Module 

The versatile RailQuad is a flexible input module that allows up to eight NTC temperature probes with known temp/resistance parameters to be connected to measure temperature.  This is particularly useful when another trade has installed underfloor probes instead of the known ones. It also contains thermostat logic functions for each input.

The Zennio 'dumb' ceiling motion sensor can also be connected for a low-cost hardware solution, although radial wiring is required for each sensor. 

Multifunction Screen

The Z35 and Z40 multifunction screens pack a heap of features into a simple to use, KNX bus connected screen that looks unobtrusive on the wall and is easy to use.

DIN Rail 4 Channel LED Driver

For a linear constant voltage LED strip, the DX4 is perfect for the distribution board. Powerful rating per channel (4 x 6A @24V) allows for longer runs and the centralised power supply can be board mounted.

Lighting under-cabinets, handrails, stair treads with LED strips add accent, task or access lighting. Controlling the light output at different levels depending on the time of day and use makes one light perform multiple functions. The DX4 is easy to programme with additional functions of sequencing, colour changing (for RGBW) strips and timed events.
