Question 1

What's your minimum order quantity, and can we start with a trial order?

Accepted Answer

MOQ depends on what you need: stock products with no customization start at 100 units — enough to test your market. Custom branding on the product requires 500 units minimum. Hardware or firmware modifications require 1,000–2,000 units due to tooling costs. Trial orders are available before larger production commitments.

Question 2

How do I know your products will pass certification in my country?

Accepted Answer

We've shipped to 47+ countries. Hardware is ISO 9001:2015 manufactured with factory functional testing. For destination markets we provide documentation packages and work with testing labs when a regional mark is required. First-time pass rate is 98% over the past 5 years.

Question 3

What kind of customization can you actually do? Is "OEM" just printing my logo?

Accepted Answer

Fair question—many suppliers use 'OEM' loosely. Logo printing and custom packaging are standard. We also modify enclosure colors, develop custom firmware for your IoT platform, adjust LoRaWAN payload maps, and create new form factors. Custom hardware and firmware projects are scoped per quote.

Question 4

How do I verify product quality and certification before a large deployment?

Accepted Answer

Hardware is ISO 9001:2015 manufactured with factory functional testing and documentation packages for 47+ markets. Quality audits and batch records are available on request. 2-year warranty with advance replacement — we ship replacements before you return defective units. Field failure rate is 0.3% across 2.5M+ units deployed.

Question 5

What's the typical lead time from order to delivery?

Accepted Answer

Stock products: 5–7 business days. OEM with custom branding: 30–45 days. Custom packaging: 45–60 days. Hardware or firmware: 60–90 days. New product development: 3–6 months. We flag delays upfront during peak season (September–December).

Question 6

Do you provide after-sales technical support, or am I on my own after purchase?

Accepted Answer

Every customer gets a dedicated account manager and technical support. Installation manuals, commissioning guides, and troubleshooting docs in 12 languages. For deployments of 500+ units we offer on-site training. 24/7 WhatsApp for urgent issues; average response within 4 business hours.

Question 7

What factory quality system do you run?

Accepted Answer

Kits are manufactured under ISO 9001:2015 with incoming, in-process, and outgoing functional tests. We provide batch records and datasheets on quote.

Question 8

Do you supply destination-market marks?

Accepted Answer

Documentation packs are issued per SKU and destination. Regional radio or food-contact marks are scoped before branding. We do not claim marks that are not issued for that SKU.

Question 9

Can OEM branding include our company name on documents?

Accepted Answer

Yes—manuals, cartons, and decoder notes can carry your brand from the OEM branding MOQ. Hardware/firmware changes follow the private-label MOQ.

Question 10

What is LoRaWAN used for on these kits?

Accepted Answer

LoRaWAN is a low-power long-range radio for industrial IoT. Our leak, level, flow, pressure, soil, weather, and food-temperature kits uplink decoder-ready payloads to your network server or ours.

Question 11

What range should I plan for?

Accepted Answer

Urban plant rooms typically see 2–5 km to a well-placed gateway; open fields can reach farther. Metal tanks and underground rooms need a site survey. Add gateways rather than over-promising a single hop.

Question 12

Can I integrate with BMS or SCADA?

Accepted Answer

Yes. Decoder profiles map into MQTT/REST, and many integrators bridge to Modbus or BACnet. These sensors report process data—they do not replace statutory safety systems.

Question 13

How do I install a leak rope or spot probe?

Accepted Answer

Run leak ropes along the lowest expected water path. Place spot probes in bunds and drip trays. Mount the LoRaWAN node where it stays dry and has a gateway path. Commission against the decoder profile, then trigger a wet test if the site allows.

Question 14

How often should LoRaWAN kits be checked?

Accepted Answer

Watch dashboard last-seen and battery fields weekly. Physically inspect leak ropes and probes during planned maintenance. Replace batteries per the datasheet interval for that SKU.

Question 15

Why am I missing uplinks?

Accepted Answer

Common causes: gateway too far, metal tanks, node installed in a riser, or report interval too aggressive for the battery. Re-survey RF and confirm the decoder is mapped to the correct payload version.

Question 16

Can facility staff install kits themselves?

Accepted Answer

Leak ropes, door contacts, and soil probes are typically installed by site technicians. Pipe flow/pressure and food-grade probes should follow the process owner’s isolation and hygiene SOPs. We provide manuals and remote commissioning support.

Question 17

How many sensors do I need?

Accepted Answer

Count leak zones, tanks, pipe branches, soil plots, and temperature check points—then add gateway coverage. We quote SKU lists after a site sketch or RF survey, not a one-size residential detector count.

Question 18

What maintenance is required?

Accepted Answer

Keep ropes and probes clean, confirm battery and last-seen, and re-zero flow/pressure after line work. Food probes follow HACCP cleaning. Document firmware versions when you OTA.

Question 19

What kit set do I need for a commercial plant room?

Accepted Answer

Most plant rooms start with leak ropes on the floor, spot probes in bunds, door contacts on risers, and a tank-level kit if you have a sump or day tank. Add pipe flow or pressure when utilities need process values, not just wet/dry alarms.

Question 20

How do kits report into my dashboard?

Accepted Answer

Each node uplinks a decoder-ready payload to your LoRaWAN network server. The dashboard maps DevEUI and payload version—not a proprietary zone panel. We supply decoder profiles for ChirpStack, TTN, and similar LNS software.

Question 21

Can I mix leak, flow, and temperature on one gateway?

Accepted Answer

Yes. Facility, industrial, agriculture, and food-chain kits share the same LoRaWAN join path. Separate them by application or device profile so operators see the right units and alarm thresholds.

Question 22

What is different about industrial yards versus plant rooms?

Accepted Answer

Yards need weather-rated enclosures, longer leak ropes, and often a dedicated outdoor gateway. Plant rooms need dry node mounting and clear last-seen monitoring. We survey both before quoting SKUs.

Question 23

Do I need 24/7 monitoring?

Accepted Answer

That is a site operations choice. Kits report to your LNS and dashboard. You decide who gets SMS/email on leak, low battery, or missed uplink.

Question 24

How do you verify manufacturing quality before a large order?

Accepted Answer

2-year warranty with advance replacement — we ship replacements before you return defective units. We are an owner-operated manufacturer with the same ownership since 2001. Batch traceability and certification documentation are provided on request.

Question 25

What's your minimum order quantity, and can we start with a trial order?

Accepted Answer

MOQ depends on what you need: stock products with no customization start at 100 units — enough to test your market. Custom branding on the product requires 500 units minimum. Hardware or firmware modifications require 1,000–2,000 units due to tooling costs. Trial orders are available before larger production commitments.

Question 26

How do I know your products will pass certification in my country?

Accepted Answer

We've shipped to 47+ countries. Hardware is ISO 9001:2015 manufactured with factory functional testing. For destination markets we provide documentation packages and work with testing labs when a regional mark is required. First-time pass rate is 98% over the past 5 years.

Question 27

What kind of customization can you actually do? Is "OEM" just printing my logo?

Accepted Answer

Logo printing and custom packaging are standard. We also modify enclosure colors, adjust sensitivity for specific environments, develop custom firmware for your IoT platform, add Zigbee, Z-Wave, or LoRaWAN, and create new form factors. Custom hardware and firmware projects are scoped per quote. We will not compromise on safety standards.

Question 28

What's the typical lead time from order to delivery?

Accepted Answer

Stock products: 5–7 business days. OEM with custom branding: 30–45 days. Custom packaging: 45–60 days. Hardware or firmware: 60–90 days. New product development: 3–6 months. We flag delays upfront during peak season (September–December).

Question 29

What samples can you ship before MOQ production?

Accepted Answer

Evaluation kits of 2–5 units ship within 5–7 days for existing SKUs. Sample fees may be credited against first production order above 100 units.

Question 30

What happens if there's a quality problem after delivery?

Accepted Answer

2-year warranty with advance replacement — we ship replacements before you return defective units.

Question 31

Do you work with startups or only big companies?

Accepted Answer

We work with distributors and integrators of all sizes. Trial orders start at 100 units for stock SKUs and 500 units for branded products. We focus on long-term partnerships rather than one-off transactions.

Question 32

What Incoterms do you support?

Accepted Answer

EXW factory is default; FOB, CIF, and DAP are available for established accounts. Freight forwarding can be arranged on request.

Question 33

How are lithium batteries shipped internationally?

UN38.3-tested cells ship under IATA/IMDG rules with proper labeling. We coordinate DG paperwork for air freight where required.

Question 34

Can you stock finished goods in EU or US warehouses?

Accepted Answer

Select SKUs are available through regional fulfillment partners. MOQ and stocking fees are quoted per SKU and volume forecast.

Question 35

Do you support UKCA marking post-Brexit?

Accepted Answer

UKCA/CE dual labeling is available on radio platforms with UK importer details. Technical-file evidence is reused from the CE/RED pack where applicable.

Question 36

What happens during Chinese New Year production?

Accepted Answer

Factory closure is typically 2–3 weeks. Place Q4 orders 60 days before CNY for March–April delivery windows.

Question 37

Who owns tooling for custom enclosure designs?

Accepted Answer

You fund tooling; molds remain at our factory for your exclusive SKU during the agreement. Firmware IP terms are defined in the OEM contract.

Question 38

How do you handle batch defects under warranty?

Accepted Answer

Log batch code and failure mode; RMA within 48 hours for confirmed manufacturing defects. Root-cause reports are shared for batches above 0.5% failure rate.

Question 39

Can we get regional distributor references?

Accepted Answer

References are available on request after NDA for active RFQs. Customer names are not published without permission.

Question 40

What export documents do you provide?

Accepted Answer

Commercial invoice, packing list, CO when applicable, test reports, and battery MSDS. HS codes are provided per SKU for customs.

Question 41

How do you reduce counterfeiting in distribution?

Serial numbers, holographic carton seals, and batch QR traceability on premium lines. Authorized partner certificates are issued to distributors.

Question 42

Can we get exclusivity for a country?

Accepted Answer

Regional exclusivity is available with volume commitments and annual business plans, negotiated after trial orders.

Question 43

What is the typical certification timeline for a new private-label SKU?

Accepted Answer

6–12 weeks on a certified platform; 4–6 months for new RF or optical designs. In-house pre-testing reduces notified-body failures.

Question 44

Do you offer end-of-life battery take-back?

Accepted Answer

EU WEEE/Battery Directive labeling is available; physical take-back depends on importer registration—we provide documentation support.

Question 45

How can I get a quote quickly?

Accepted Answer
