Discuss customisation

Overview & features

A stand-alone plug-in terminal built around the ESP32-C3, with on-board Wi-Fi, an IR transceiver and an energy-metering IC. It measures the air conditioner’s voltage, current, power and energy consumption and publishes the data over MQTT, and sends IR commands to control power, temperature, mode and fan speed from an updatable code library. Meets CCC requirements for switch sockets, includes over-voltage and over-current protection, supports hotspot / one-tap onboarding and preset server addresses, and integrates with an air-conditioner monitoring system.

Key features

  • Single-phase energy metering: voltage, current, power and energy
  • IR transmitter covers common air-conditioner models, with an online-updatable code library
  • Over-voltage protection against lightning surges; automatic cut-off above rated current
  • LED blink patterns show operating mode; hotspot or one-tap onboarding
  • Compact plug-and-play form factor; supports preset server address and initial parameters

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.
