Here comes the OTA notes for v1.5:
https://github.com/marvinroger/homie-esp8266/blob/v1.5.0/docs/4.-OTA.md

and the changes for OTA update in v2.0:
https://homie-esp8266.readme.io/v2.0.0/docs/ota-configuration-updates

OTA is now done over MQTT

Source: homieiot/homie-esp8266#87

Could you please implement OTA updates for v2.0 (which was the primary reason for using homie-ota)?

Thanks!

I'm ota-updating Homie v2 nodes with homie-ota without any problems.

Encountered a couple of issues which I'm guessing are as a result of homie v2:

  • Device list doesn't get populated at all. Cant even attempt an ota update.
  • When trying to upload a compiled sketch I get the following error:
    Cannot write ./firmwares/itead-sonoff-buton�Dk�uj?>��1.0.0�0H��switchj?>��1.0.5�0H������Texample-firmware-1.0.0�0H��switchj?>��1.0.5.bin: file() argument 1 must be encoded string without null bytes, not str

Thank you for your time.

Homie v2 already adds the necessary magic strings for OTA naming in homie.setFirmware, see homieiot/homie-esp8266@e73b3af in src/Homie.hpp. So it is possible that when you follow the example sketch here you end up adding the magic bytes twice which could explain the odd filenames observed by @derp00herp.
