FAQ
How soon will I hear back after submitting an inquiry?
Usually within 4 hours during working hours. For requests involving a custom solution, an engineer gets in touch within one working day to confirm the details.
Why doesn’t the site show prices?
Hardware and solution pricing depends on quantity, degree of customisation, certification and delivery requirements, so we issue a formal quote against each inquiry. Reference prices and MOQs for standard items are available when you inquire.
Is there a minimum order quantity?
Samples and small pilot runs are both available; the mass-production MOQ is stated in the quote and depends on the product and its materials.
Can you help with certification?
Yes. We arrange testing and certification for the target market — CCC, CE, FCC, SRRC, RoHS and others — with cost and lead time itemised in the quote.
Can the devices connect to our own cloud platform?
Yes. The firmware supports MQTT / HTTP integration with your own platform or a public cloud IoT platform; you can also use our cloud platform and mini-program monitoring service.
How do you handle after-sales support and firmware updates?
Mass-produced products come with OTA firmware updates and technical support; repairs and replacements are handled under the warranty period agreed in the contract.
