Still have questions?
We're happy to walk through your floor plan and answer anything not covered here.
Most homeowners start with a short consultation to align on what you want the home to do (e.g., lighting, air-conditioning, curtains, safety automations), then build a sensible base setup that can expand over time.
You can see the full flow on our How It Works page.
What is a smart home?
A smart home lets things like lights, air-conditioning, curtains, and appliances respond automatically to how you live — based on routines, conditions, or schedules — instead of needing manual control each time.
Is Home Assistant hard to use?
Home Assistant can be powerful, but daily use does not have to be complicated. Most homeowners interact with simple dashboards, automations, or voice control, rather than technical settings.
Do I need to be tech-savvy?
Not at all. We handle the technical setup and aim to make daily use straightforward. Most interaction happens through simple dashboards or automations.
Costs & Value
How much does it cost?
For most Singapore homes, the typical range is $2,000 to $3,000. This usually covers planning, setup, and core devices like smart switches. Costs vary depending on home size, device choices, and whether rewiring is needed.

Does Home Assistant require a subscription?
TL;DR: Home Assistant runs without any subscription.Home Assistant runs without any subscription. Optional services are available, but they are not required for normal operation.
Are there ongoing costs after the initial setup?
The main cost is upfront. After that, Home Assistant has no subscription fees. You might spend on replacement devices or adding new ones over time, but there are no mandatory recurring charges. Some optional cloud services exist, though none are required.
Can a smart home help reduce my electricity bill?
It can. Automations that turn off lights and air-con when no one is around help most households trim usage. The smart devices themselves barely sip power — keeping a single smart switch on for an entire year costs less than a packet of chicken rice.
Home Assistant & Platforms
What is Home Assistant?
Home Assistant is an open-source smart home platform that acts as the central system for your home. It allows devices from different brands to work together in one place, instead of being spread across multiple apps.
If you're new to it, we have a beginner-friendly overview on our Home Assistant page.
Why do you use Home Assistant?
We use Home Assistant because it is designed for long-term ownership and flexibility. It supports local control, works across many brands, and allows a smart home system to grow and change over time without being tied to a single company or business model.
What does no vendor lock-in mean?
It means your smart home is not tied to a single brand or ecosystem. Devices can be replaced, upgraded, or mixed over time without having to rebuild the entire system from scratch.
Is Home Assistant suitable for everyone?
TL;DR: Not always — it depends on what you value.Home Assistant suits homeowners who value flexibility, control, and long-term ownership. Those who prefer a single-brand, plug-and-play system may prefer other options.
Why not just use Google Home or Apple HomeKit?
They work well for simple setups, but hit a ceiling once you want automations that respond to multiple conditions — like adjusting lights based on time, presence, and weather at once. Home Assistant handles that depth while still letting you use Google or Apple for voice control on top.
Can I use voice control with Home Assistant?
Yes. Home Assistant works with Google Assistant, Amazon Alexa, and its own local voice assistant called Assist. You can mix and match, or go fully local if privacy matters to you.
Devices & Compatibility
Can I mix different brands?
TL;DR: Many brands can work together under one system.Home Assistant supports a wide range of integrations across many brands.
This allows different devices to work together within a single system, subject to compatibility.
Can you integrate devices I already own?
Often, yes — and we'll assess what you already have before recommending anything new. Compatibility depends on the device model and how it communicates (local vs cloud).
If you're unsure, our Services page explains how we approach planning and integration.
What can I make smart?
Many electrically powered things can be automated in some way — including lights, curtains, fans, air-conditioning, door locks, and selected appliances. Feasibility depends on the device and how it is used.
Can you help design or integrate my smart lighting or switches?
Yes. We can help plan and integrate smart lighting in a way that fits your home and how your household uses it. The right approach depends on your existing wiring, device choices, and what you want the lights to do.
Our approach is explained on the Services page, and the project flow is on How It Works.
What smart home protocol should I use — Zigbee, Wi-Fi, or Matter?
There are a few options, and the right one depends on your home layout, how many devices you plan to use, and what you already have. Some protocols handle Singapore's dense housing better than others. We help figure this out during consultation so you don't have to research it yourself.
Can I use cheap smart devices from Shopee or Lazada?
TL;DR: They can work, but reliability varies.You can, but many are Tuya-based OEM products that depend on cloud servers and may not integrate reliably with Home Assistant. Response times can be inconsistent, and firmware updates from the manufacturer can break integrations without warning. We recommend devices with proven local control.
Will smart switches work with my ceiling fan?
Standard AC fans usually work fine. DC fans (increasingly common in Singapore) need compatible controllers since they use different electronics. We check fan types during planning so the right hardware is matched.
What are presence sensors, and why do they matter?
You probably know motion sensors — the ones in HDB corridors that turn on when you walk past. Presence sensors are similar, but they can tell if someone is sitting still in a room, not just passing through. That difference matters for automation accuracy.
Installation & Wiring
Do I need to rewire my home?
TL;DR: Usually not.Many Singapore homes use no-neutral wiring, and compatible smart switches exist for both wiring types. We generally avoid heavy electrical work; your electrician can handle wiring during renovation, and we only step in if specific changes are needed (e.g., switch replacements or faulty lights).
We explain this more clearly on our How It Works page.
What is a neutral wire, and does my home need one?
TL;DR: Most Singapore homes don't have one, but there are workarounds.A neutral wire completes the circuit that most smart switches need to stay powered. Most Singapore homes — new builds included — don't have one unless the electrician specifically ran it. Compatible no-neutral switches exist, but if you're renovating, it's worth asking your electrician to pull neutral wires for the widest device options.
How long does setup take?
TL;DR: Mostly planning and setup; on-site work is usually 1–2 days.Most projects focus on planning, setup, and configuration rather than heavy installation. Electrical work is typically done by your electrician during renovation, and we step in only when necessary (e.g., switch changes or troubleshooting faulty lights). Timelines vary by scope and home size, but we aim for minimal disruption.
Can this be installed after renovation?
TL;DR: Yes, but it's easiest to align during renovation.Many setups are retrofit-friendly, but the easiest path is to align during renovation with your electrician. We can integrate and configure the system, and step in only when specific electrical changes are required.
Will this work in older HDB or resale flats?
TL;DR: In most cases, yes.Older homes may have additional constraints, but smart home systems can usually be designed to work within them. Any limitations are discussed clearly during consultation.
Is a smart home worth it for a small HDB flat?
Smaller homes actually benefit more — fewer devices cover the whole space, and automations have a bigger impact when rooms overlap in function. A 4-room HDB can be fully automated for less than you might expect.
Automation & Daily Use
What kind of automations can I set up?
Automations can be based on time, presence, or conditions in the home. For example, lights turning off automatically, air-conditioning adjusting before you arrive, or devices running only when no one is home.
Can I control things when I'm not home?
Yes. Remote access can be enabled so you can monitor and control devices when you are away, depending on the access method chosen.
Do smart homes use a lot more electricity?
Smart home devices themselves use very little power. In many homes, automation actually helps reduce electricity usage by turning things off when not needed or optimising air-conditioning usage.
How do I interact with my home day-to-day?
Most people use a mix: physical switches still work as normal, a phone app or wall tablet shows a simple dashboard, and voice commands handle quick tasks. The best automations run silently in the background — you only notice when your home just works.
Privacy, Security & Reliability
Who owns and controls the smart home system?
You do. The system runs on hardware in your home, and the software and core functionality does not expire or require a subscription to continue working. You are not dependent on an installer's account or an external company to operate your smart home.
Is it secure?
TL;DR: Security is configurable based on how you want to access the system.Home Assistant supports different access models, ranging from fully local-only setups to remote access with additional protections. The level of exposure can be adjusted depending on your needs and comfort level.
Is it private?
TL;DR: Home Assistant runs locally, keeping most data within your home.Home Assistant is designed to run locally within your home network. This keeps most data processing inside your home and reduces reliance on external cloud services.
What if my internet goes down?
TL;DR: Most things keep working.Home Assistant is designed to run locally in your home. Core functionality such as lighting, switches, and sensors can continue to function during internet interruptions, depending on how the system is set up.
Will smart home devices burden my Wi-Fi?
TL;DR: Usually no, when designed properly.Many smart home devices do not rely heavily on Wi-Fi, and core automations run locally. Even with cameras, a typical Singapore home network is usually sufficient when the system is planned sensibly.
What happens during power outages?
TL;DR: The system is designed to recover gracefully.Devices we recommend typically reconnect when power is restored, and automations are designed to return the system to a stable state over time. Behaviour can vary with third-party devices.
Does the system need maintenance?
TL;DR: Maintenance is usually minimal.Routine maintenance is minimal for most households. Updates are generally straightforward, and we're available to help if changes are needed.
Will this work with my existing router?
TL;DR: Usually yes.Most home router setups do not require special configuration. If there are network-related constraints, we can advise on them, though our focus is smart home design rather than full network reconfiguration.
What happens if a device brand disappears?
TL;DR: Devices that work locally usually keep working.Devices designed for local operation are generally not affected if a company shuts down. Some third-party devices that depend on vendor servers may behave differently, which is why device selection matters.
What happens if a cloud service or smart home app shuts down?
TL;DR: Local devices keep working. Cloud-dependent ones are the risk.Devices that run locally through Home Assistant keep working regardless. Cloud-dependent devices are the risk — if the company closes its servers, those devices may stop responding. This is a key reason we favour local-first hardware.
Support & Ownership
Can I expand the system later?
Yes. Home Assistant is designed to be flexible and expandable. New devices and automations can be added over time as your needs evolve.
Will you teach me how to use it?
Yes. We provide a walkthrough after installation so you're comfortable using the system and understand the basics.
What about support after installation?
Support is structured and depends on the agreed scope. Early issues are usually addressed quickly, with a mix of on-site and remote support when appropriate.
Can I move or hand over the system later?
TL;DR: Yes, the system is designed with handover in mind.Smart home systems are typically handed over to the next homeowner. If needed, the central system can also be reused in a new home, subject to legal and practical constraints.
Do smart homes affect home resale value?
When designed properly, smart home features can be a positive selling point. Systems are set up so they can be handed over clearly to the next homeowner.
Is there a warranty?
Yes. We provide a 12-month warranty on our installation and integration work. Devices supplied are covered according to their respective warranties.
