H2A Bluetooth enabled with Mesh Wireless Lighting Control System

Frequently Asked Questions

What are wireless lighting controls?

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.

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

Bluetooth enabled with 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.

What is a remote device?

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 enabled and 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. The Kinetic operated remote does not need battery ever.


A remote that is powered by kinetic energy does not have a battery cell, will not need battery replacement ever.

What is a receiver?

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.

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

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

Do you support constant current and constant voltage led controllers?

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

What does H2A APP do?

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.

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

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.

Do I need Wi-Fi to operate H2A?

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

Do I need a hub to operate H2A?

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.

Will wall switch plates and handheld remotes still work with Bluetooth enabled on the mobile phone/tablet?

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

Do I need IT specialists to support H2A?

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.

How secure is H2A?

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.

Can scenes be changed after commissioning?

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

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

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.

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

Up-to 180 units in any mix are supported.

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

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

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

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.

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

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.

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?

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.


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

Yes, when linked with Alexa or Google home.

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

iOS 12.0 and above, from Apple App Store

Android 5.0 and above, from Google Play

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

Yes. You can achieve that by specifying the time windows for on/off in scheduling.

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

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

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

No. Each switch (remote) must be paired with the circuit of lights (receiver)

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

Yes. The additional switch must be paired, then programmed to operate.

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

Yes, you would use a relay instead of a dimmer.

Can my curtains and blinds be linked to a scene?

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

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

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

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?

Yes. You can do this via Alexa and Goggle Home.

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

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.

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

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.

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

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

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

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

I want my son to control his room and nothing else, is this possible?

Yes, set up his room as a separate group with his lights only.

I would like to programme the switch by the front door as an all on/off switch, is this possible?

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

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

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