• 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

• 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

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