Antsig Smart Wi-Fi IR Universal Remote (HUBIR01HA)

Overview

Sold at Bunnings in Australia. Model number HUBIR01HA. Based on the CB3S module, natively runs Tuya. This configuration provides climate control but the device is a generic IR blaster that can control a wide range of IR devices. Flashing is achieved by popping off the top cover and soldering to easily accessible pads for UART. tuya-cloudcutter is untested - it may work but it’s quite an easy device to flash by serial.

GPIO Pinout

Flashing

• Open the blaster by prising off the translucent top - it’s not glued or welded but does have a fair few clips holding it together
• Solder wires to the pads for 3V3, RST, TX, RX, and GND
• Connect 3V3, TX, RX, and GND to your USB UART adapter, and RST to GND (temporarily)
  • Note that if you have trouble flashing you may need to source a reliable 3.3V supply from some other place
• Generate a UF2 firmware file with ESPHome and flash using https://docs.libretiny.eu/docs/flashing/tools/ltchiptool/ - once you’ve clicked Start, disconnect RST from GND
  • This can take a few goes sometimes
• Once flashed, disconnect the wires and power from USB - any further updates you need to make can be done OTA (which is usually much faster)
• Take care when replacing the top - the clips aren’t evenly spaced so you’ll need to line them up right for it to go back together
