  • ESPurna firmware

    Andrey Kupreychik • 01/04/2019 at 14:24 • 0 comments

    Hi all!

    After researching thru ESP modules firmware options I found a better option of the firmware for the switch. It's ESPurna firmware. The main advantages I see in ESPurna are: compile-time module definition and async MQTT.

    Currently ESPurna firmware for LightFox dual is tested on my instances. It works OK. The firmware is available for download on github: https://github.com/foxel/esp-dual-rf-switch/blob/v3/esp01-firmware/espurna-1.13.4-dev-foxel-lightfox-dual.bin

  • Updating to V3. Pushing to Tasmota

    Long time no see guys.

    The best news for the project is that it got to stable version tested and deployed :) Bad news later.

  • Firmware is ready, project is on github

    Andrey Kupreychik • 03/09/2018 at 14:32 • 0 comments

    First fimware is ready to be used. 

    Was trying to use attiny44 instead of 441 for a week but failed with software UART timings.

    Then received 441 which was initially planned and UART worked like a charm.

    The firmware is split in two parts: ESP8266 firmware and Attiny441 firware.

    For ESP8266 part i've decided to fork Sonoff-Tasmota and use Sonoff DUAL UART protocol for controllers communication. For attiny i've designed firmware by myself. 

    Currently the main use-case is covered and I can control channels from RF and MQTT. Still need to address RF binding/cleaning by triggering button from attiny.

    Also the project is now available on GitHub: https://github.com/foxel/esp-dual-rf-switch

    And finally demo:

  • I've got PCBs... and assembled first switch

    Andrey Kupreychik • 02/17/2018 at 18:06 • 0 comments

    So I recently received PCBs from jlcpcb.com. It cost me about $8 including delivery. Pretty cheap I think.
