Unexpected error with generic-rtl8720cf-2mb-992k board

[rkorn86]

Hi there,

as stated on https://docs.libretuya.ml/boards/generic-rtl8720cf-2mb-992k/, this board should be supported.

Adopting the ESPHome example from https://docs.libretuya.ml/docs/projects/esphome/ and changing board accordingly results in an error:

$ python -m esphome compile example.yml 
INFO Reading configuration example.yml...
INFO Generating C++ source...

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq/index.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

============================================================

Other generic boards, like generic-rtl8710bn-2mb-788k, compile with other errors (out of scope of this issue):

src/esphome/components/libretuya/core.cpp: In function 'void esphome::arch_init()':
src/esphome/components/libretuya/core.cpp:22:6: error: 'class LibreTuya' has no member named 'wdtEnable'
   LT.wdtEnable();
      ^
src/esphome/components/libretuya/core.cpp: In function 'void esphome::arch_feed_wdt()':
src/esphome/components/libretuya/core.cpp:33:41: error: 'class LibreTuya' has no member named 'wdtFeed'
 void IRAM_ATTR HOT arch_feed_wdt() { LT.wdtFeed(); }

Do you have any idea?

No, this board is not supported. As stated in "board families", this family doesn't support the Arduino framework yet, which is needed for ESPHome.

Regarding the second issue, this means that LibreTuya you're using is outdated. See "getting started" on how to install the latest version.

[rkorn86]

Thanks for clarification.
Regarding second issue: I am using the latest version of https://github.com/kuba2k2/libretuya-esphome commit 090809cfb6affa3b64a9e715dac5e337295feabc (HEAD -> platform/libretuya, origin/platform/libretuya, origin/HEAD) and installed platformio platform using platformio platform install -f https://github.com/kuba2k2/libretuya

Nethertheless thanks for your great work. Seems, like I have to resolder this goddamn WBR3 with an ESP or just return my ME81H Floor Heating Thermostats

[kuba2k2]

Well, whatever happened during the compilation made LT install the older version. These two functions wdtEnable and wdtFeed were introduced some time ago, so if you update again using platformio platform install -f https://github.com/kuba2k2/libretuya it will work just fine.

If you don't mind sticking with the Tuya firmware for some more time, you can wait until LT supports that. (yes, it's planned as well)

[rkorn86]

Sounds great. I will apply as beta tester, as I am not in a hurry with replacing my old thermostats.

PS: running platformio platform install -f https://github.com/kuba2k2/libretuya again did the trick - example successfully compiled - INFO Successfully compiled program.
