Part of our Smart Home OEM Manufacturing Guide — the complete resource for brands sourcing from a smart home OEM manufacturer.
Buying smart home products at factory price sounds simple until you compare three quotations for what looks like the same smart switch. One is 30% cheaper, one includes certification you did not ask for, and one quietly assumes a minimum order you cannot sell through in a year. This guide is written for distributors, importers and retailers who source smart switches, cameras and sensors in volume and need to tell a real factory price from a number that only looks low.

What “factory price” actually means in smart home sourcing
A factory price is not one number. It is a price tied to a specific configuration, a specific order quantity and a specific set of certificates. When a supplier quotes a smart switch, the cost sits on top of the enclosure, the PCBA, the relay rating, the wireless module and the firmware that runs on it. Change any one of those and the price moves. A quote that does not state which module is inside, which load the relay is rated for, and whether certification is included is not comparable with a quote that does.
Practically, this means your request for quotation should list the configuration before you ask for the price. Buyers who send a photo and ask “how much” get a wide range back, and the cheapest number in that range is usually the one built to the lightest specification.
Smart switches: what to specify before you request a quote
For switches, the decisions that drive cost are the panel material (glass, PC, metal), the wiring situation in your market (neutral wire present or not, single live wire), the load rating, and the wireless protocol. A switch built for a market where homes have a neutral wire will not work in older buildings without one, and a switch that omits the neutral requirement costs more per unit because the power design is harder. Decide this before tooling, not after.
The protocol choice matters in the same way. A Wi-Fi switch is the cheapest to build and the easiest to install, but it puts every device on the customer’s router. Zigbee and Matter-based switches need a gateway, which raises the entry cost of the kit but lowers support tickets later. If you are building an ecosystem rather than selling a single SKU, the gateway decision belongs in the first conversation.
Cameras and sensors: where the real cost drivers are
Camera cost is driven by the sensor, the lens, the storage path and the amount of on-device processing. Two cameras that look identical from the front can differ by a factor of two in bill of materials, and the difference is invisible in a specification sheet that only lists resolution. Ask which sensor and which SoC are used, whether night vision is IR or full-colour, and whether AI detection runs on the device or in the cloud. Cloud-side detection is cheaper up front and carries an ongoing server cost that eventually lands in your margin.
Sensors look like the easy category and are the easiest to get wrong, because the failure mode is battery life rather than functionality. A door sensor that dies in four months generates returns and reviews you cannot recover from. Ask for the standby current, the battery model and the expected life under a realistic trigger count, and put it in the purchase contract rather than in an email.
MOQ, tooling and lead time: three numbers that decide your margin
Every sourcing decision eventually comes down to three numbers. The minimum order quantity decides how much cash you tie up in the first buy. The tooling cost decides whether a custom enclosure or PCBA makes sense at your volume. The lead time decides whether you can react to a season or have to commit a quarter ahead.
For off-the-shelf models with your branding, minimums commonly start in the low hundreds per model. For a genuinely custom enclosure, tooling adds an upfront cost and several weeks to the schedule, which only pays back once you have a volume plan across more than one order. A useful rule: if you cannot place a second order within six months, take the standard housing and spend the money on packaging and certification instead.
Certifications and compliance by destination market
Certification is where “cheap” quotations quietly become expensive. Radio products need approval in every market you sell into, and the test is done on the finished product, not on the module alone. Budget for the certificates your destination actually requires, and ask the supplier which ones they hold for the exact model you are buying. A supplier who offers to “add CE later” is telling you the current unit is not approved.
For battery-powered devices there is an additional layer: transport documentation for lithium cells, and in many markets a registration obligation on the importer rather than the factory. Clarify which party carries which document before the goods reach the port, because this is the step that most often delays a first shipment.
How to vet a smart home wholesale supplier
A smart home wholesale supplier should be able to answer four questions without going back to an engineer: which module and firmware version this model runs, which certificates are held and for which model code, what the standard lead time is at your quantity, and what happens to a defective unit after arrival. Factories that develop their own hardware can usually also tell you what they changed between revisions and why, which is a good sign that you are talking to the people who build the product.
Ask for a sample from the current production run rather than a hand-built demo, and test it the way your customer will: put it on a real network, run it for two weeks, and check whether the app still behaves after a firmware update. Order one carton before you order a container.
Private label or ODM: which route fits your channel
Private label takes an existing model and puts your brand, packaging and manual on it. It is fast, the tooling cost is near zero, and the certification already exists. It works well when you need to fill a catalogue quickly or test a category. ODM starts from your requirement and ends with a product nobody else sells. It takes longer and needs a volume commitment, but it is the only route that gives you a defensible price because there is no identical unit to compare against.
Most distributors use both: private label to enter a category, ODM once the volume justifies it. The mistake is choosing ODM for the first order in a category you have not sold yet, because you then carry tooling cost and a long lead time on an unproven demand.
Frequently Asked Questions
What is a realistic MOQ for a first smart home order?
For branding an existing model, hundreds of units per model is typical and sometimes negotiable if you consolidate several models into one shipment. A fully custom enclosure or PCBA is a different conversation, because tooling has to be recovered. Ask the supplier to quote both options before you decide.
How long does a custom smart switch project take?
Plan in stages rather than in weeks: specification and quoting, tooling for the enclosure, prototype, certification testing, then mass production. Prototypes can arrive quickly; certification is the stage that is easiest to underestimate and the hardest to compress.
Which certificates do I need for the EU and UK?
Radio equipment needs the approval applicable in that market, plus the general product safety and material requirements, and the documentation has to carry the importer’s details. Confirm the exact list with your compliance adviser for the destination country, and make sure the certificate is issued for the model code you are actually buying.
Can I mix product categories in one container?
Yes, and it is usually the sensible way to fill a first shipment, because it spreads risk across categories and avoids a single slow-moving SKU occupying all your cash. Keep the paperwork per model code clean, since customs and certification are handled per product, not per container.
How do I avoid quality surprises before shipment?
Write the acceptance criteria into the contract: which tests are run on what share of the batch, what the failure threshold is, and what happens when the batch fails. Then use a pre-shipment inspection against that written standard. An inspection that finds nothing is still useful, because it is the only evidence you have if the next batch differs.
