Question 1

What are wireless lighting controls?

Accepted Answer

Lighting control signals were traditionally communicated through low voltage wired cables
between a centralised microprocessor-based controller and devices. In wireless
lighting, control signals are communicated through radio waves to remote devices and
receivers. 230V hardwire cabling is still required but allow more flexibility in cable run.

Question 2

What is Bluetooth mesh lighting control and how does it work?

Accepted Answer

Bluetooth mesh lighting control is where a collection of a few or large collections of remote
devices, receivers, mobile phones and tablets, communicate bi-directionally with each other
through radio waves within a mesh networking without the need of a centralised control
panel hidden in a closet or utility room. A mobile App is available to download for
programming and configuring the whole system.

Question 3

What is a remote device?

Accepted Answer

A remote device is a smart device used to control lights, on/off, dim up/down, change scene,
change colour temperature, etc. A remote device can be a switch plate, a handheld
controller and an App running in a mobile phone/tablet. Commands generated by remotes
are sent via Bluetooth wirelessly to the respective receivers. Through Bluetooth mesh
networking, receivers will get message(s) relayed to each, but only the right receiver will
action the task.
A remote device can be battery or battery less (kinetic) operated. Controls instructions are
held in each remote’s local flash memory. When battery runs flat, once replaced with new,
normal operation will resume.

Question 4

What is a receiver?

Accepted Answer

Receivers are smart devices, typically, they are phase dimmers, LED controllers, relays,
curtain controllers, DALI converters to name a few. When a receiver gets a message that
matches with its ID, it will execute the instruction resulting in diming level raised/lowered,
RGBW colour changed, lights switched on/off etc. In the case of a DALI converter, it sends a
DALI message to the intended DALI driver to carry out DALI functions.
Controls instruction is held in each receiver’s flash memory. When power to the receiver(s) is
lost, data will not be lost. Once powered up again, it will resume normal operation.

Question 5

Can you add or remove remotes and receivers from an already commissioned system?

Accepted Answer

Yes - Adding, removing, and replacing any remote devices or receivers after commissioning
are possible, easy, and secure.

Question 6

Do you support constant current and constant voltage led controllers?

Accepted Answer

Yes, both types are supported (refer to specific data sheet for load capacity)

Question 7

What does H2A APP do?

Accepted Answer

H2A Application is a powerful suite of software running on an iOS/Android mobile device. It
is downloadable from the respective stores. The APP works with Bluetooth enabled mobile
phones and tablets.
The App is a programming tool as well as a “remote”.
When used as a programmer, it pairs & configure receivers; programme scenes, create
control groups, scheduling, change fade rate from default etc.
When used as a “remote”, it carries out lighting control functions, same as a wall switch
remote.
After programming, the App acting as a “remote” is used to test/commission the area under
control. Once the system is commissioned, a copy of the database is stored in our secured
cloud server. A QR code is generated for quick access to download the saved data which
can be duplicated to another mobile device or used for recovery purposes. This is a
managed process, only available to Owners and Managers of the properties.

Question 8

In a crowded room such as a restaurant, can anyone’s mobile phones with Bluetooth switched on and interfere with H2A lights?

Accepted Answer

No. For H2A to act as an active operating “remote”, the mobile phone/device must be
running H2A app with a copy of the venue’s database duplicated on the mobile device.

Question 9

Do I need Wi-Fi to operate H2A?

Accepted Answer

No. H2A needs Bluetooth enabled only, any mobile devices with iOS version 12 and above
and Android V5 will support H2A App.

Question 10

Do I need a hub to operate H2A?

Accepted Answer

No, it does not need a hub. H2A devices operate in Bluetooth mesh networking, mobile
device’s Bluetooth must be switched on to allow communication between the mobile device
and H2A receivers, remotes.
We do however offer a WIFI hub (TEQ-GW-SB). This allows for voice control via Alexa or Google Home.

Question 11

Will wall switch plates and handheld remotes still work with Bluetooth “turned off” on the mobile phone/tablet?

Accepted Answer

Yes. Wall and handheld remotes have their own inbuilt Bluetooth communication, do not
require a mobile to provide the communication path

Question 12

Do I need IT specialists to support H2A?

Accepted Answer

No, it does not need any IT specialists support, a mobile application savvy person can
support H2A application. A trained electrician is expected to support the electrical
installation.

Question 13

How secure is H2A?

Accepted Answer

H2A is completely secured. It operates via Bluetooth mesh networking, communicating with
H2A receivers and remotes which are paired with the mobile device through a manual
commissioning process. Hacking in the mobile device cannot interfere with the system.

Question 14

Can scenes be changed after commissioning?

Accepted Answer

Yes, any previously set operating parameters can be changed through the App or by
reprogramming from the remotes.

Question 15

If I need to change some of the scenes, do I need a specialist to do reprogramming?

Accepted Answer

No, reprogramming is relatively easy, can be undertaken by an inhouse authorised person
such as an engineer, a mobile application savvy person. In addition to an operating manual,
there are a series of videos to aid. If there is a service contract in place, the service provided
should include re-programming in the contract.

Please see the "How To" section

Question 16

How many receivers/remotes are supported by one H2A system?

Accepted Answer

Up-to 198 units in any mix are supported.

Question 17

Can I see what lights are on/off on the App display?

Accepted Answer

Yes, from the mobile App, it displays status of each receiver and their respective light levels

Question 18

Do I need a special repeater to extend mesh network coverage?

Accepted Answer

No, there is no special repeater needed. Range and coverage can be extended by adding a
receiver (dummy) in the location determined after a walk test. Alternatively we also the TEQ-SB2100AMP Signal booster.

Question 19

I have some DALI controlled circuits; can I include them under H2A control?

Accepted Answer

Yes, by adding a “Bluetooth to DALI” converter on the DALI Bus, DALI circuits can be
controlled in broadcast mode; by adding more converters, finer control by group or short
address is possible.

Question 20

Can existing electrical circuits be re-used or must new ones be installed to retrofit H2A smart lighting in any target venue such as homes, offices, meeting rooms etc?

Accepted Answer

Every existing circuit can be re-used, there is no need to pull new cables unless new circuits
are added to the property.
The property’s lighting can easily be turned into modern smart lighting by putting receivers to
strategic light sources; changing bulbs, led lights to dimmable type. Soft light, scenes can be
programmed to provide comfortable environment for any occasions.
An existing circuit with many luminaires can be converted into smart lighting in two ways.
a) By adding a receiver/dimmer behind the existing switch plate will allow that circuit to be
controlled wirelessly as a single group. All the luminaires must be changed to dimmable
types to be dimmable.
b) By adding receivers to each luminaire of the same circuits allow each luminaire to be
controlled independently. This allow the circuit to be programmed into multiple
scenes/groups.

Question 21

Can I use voice control to switch on/off/change scenes?

Accepted Answer

Yes, when linked with Alexa or Google home

Question 22

What versions of OS support H2A App? And where I can get it from?

Accepted Answer

iOS 12.0 and above, from Apple App Store
Android 5.0 and above, from Google Play

Question 23

Can I programme my lighting to come on/off at certain times?

Accepted Answer

Yes. You can achieve that by specifying the time windows for on/off in scheduling.
Each receiver has a built in 24 hour, 7 day 365 astrological clock built in.

Question 24

Can H2A be used to add garden lighting to the system?

Accepted Answer

Yes. By installation the correct type of receivers, e.g. a relay will provide on/off; a LED
controller with RGBW features will allow colour change to Led lights

Question 25

Is there a limit to the number of switches I can use to control a circuit of lights?

Accepted Answer

Yes. Each receiver can be controlled by > 8 Wall switch plates. 
Each switch must be paired with the circuit of lights (receiver)

Question 26

Can I add an additional switch to the system once programmed?

Accepted Answer

Yes. The additional switch must be paired, then programmed to operate all through the App.

Question 27

My lighting does not dim. Can I use H2A just to switch my lights on/off?

Accepted Answer

Yes, you would use a relay instead of a dimmer.
If a dimmer is used on a non dimmable circuit. Damage to either the receiver or the light will happen.
Please ensure all light fittings or Lamps on a circuit are either dimmable or non dimmable and use the correct receiver.

Question 28

Can I set a colour on my RGB lighting to a scene?

Accepted Answer

Yes. You can set colour to a scene from the App

Question 29

Can my curtains and blinds be linked to a scene?

Accepted Answer

Yes, you can, by programming these as if they are lighting circuits from the APP

Question 30

I don't want to use lots of apps to control my cinema room, can I use Voice control to set the lighting, blinds and AV all in one command?

Accepted Answer

Yes. You can do this via Alexa and Goggle Home

Question 31

My lighting circuit is over 200 watts, can I still use H2A?

Accepted Answer

Each phase dimmer receiver can handle maximum 200 watts, if your total circuit exceeds
this threshold, you will need to split the circuit to multiple circuits, each within 200watts. Each
circuit will require a receiver. In a domestic setting no circuit should ever exceed this amount of lighting.
Our maximums are 400 watt of incandescent lighting (No longer sold)  or 200 watts of LED lighting

Question 32

I have just purchased a new table lamp, can I add this to the system?

Accepted Answer

Yes, you need to add a smart phase dimmer receiver, in-line type, to the circuit connected to
the new table lamp. This in-line dimming product is available in 2022.
Please ensure your table lamp is fitted with a dimmable LED lamp.

Question 33

What happens if there is a power cut? Do I need to re programme the whole system?

Accepted Answer

No. When power returns, the system will resume working, the operating program is stored in
the receivers

Question 34

I want to add the app to my colleague’s phone, do we need to reprogramme from scratch?

Accepted Answer

No. Download H2A from the Apple store or Goggle Play on your colleague’s phone, recover
the backup QR code from your saved back up, run duplicate from your colleague’s phone
running H2A, check out our video for exact procedure

Question 35

I want my colleague to control his office and nowhere else, is this possible?

Accepted Answer

Yes, you can set up a master switch group with all the lights in the house that will do all
on/off

Question 37

My lights turn off really fast, can I slow this down?

Accepted Answer

You can change the fade rate to slow down the turning on/off times, from default 2 seconds
to maximum 5 seconds.

Question 38

One of my lights stop working after many months, what would be the likely cause?

Accepted Answer

It is very likely the bulb has blown. Make sure the bulb is replaced with same type of bulb,
dimmable type.
