[alexxx113]

Can I help? logs? tests?

[kuba2k2]

Not really. Seems like CHANGE interrupts were "supported" previously, only due to a bug that produced undefined behavior. Realtek doesn't support CHANGE interrupts properly and that's why it's failing now.

When you tried 1.1.0, did it actually report correct energy measurements? Or just produced no warning?

[alexxx113]

version: 1.1.0 work no problem

I'm encountering the same issue on a generic-rtl8710bx-4mb-980k with the hlw8012 platform.

But for me LT 1.1.0 causes a Hard Fault Error when opening the web browser.

My guess is that it is related to the change introduced in 1.2.0 which adds preliminary support for RTL8720C.

https://github.com/kuba2k2/libretiny/blob/f3871388ce54bf277f2067370ee99c57b677e186/cores/realtek-amb/arduino/src/wiring_irq.c#L65

[SuperXL2023]

I found a temporary solution. Slightly modified the code in the file: < config dir >/.esphome/platformio/platforms/libretiny/cores/realtek-amb/arduino/src/wiring_irq.c

file: wiring_irq.c

...<other code> 
62: #if LT_RTL8720C
63:                        event = IRQ_FALL_RISE; // <- BUG  [ IRQ_FALL_RISE ] not defined, the compiler stops at this point with an error
64: #elif LT_RTL8710B
65:                        event = IRQ_RISE;
66: #else
67:                        LT_W("CHANGE interrupts not supported !!!!!!");
68: #endif
...<other code>

First I tried to add to line 62: #if LT_RTL8720C || LT_RTL8710B, but the compiler stopped here with the error IRQ_FALL_RISE not defined after that, I added lines 64, 65 and everything compiled perfectly and worked.

I hope this bug will be fixed in the next version of the library, and I hope my temporary solution will help you.

Having the same issue on the WR3E using the RTL8710BN in ESPHome with a MOES iR and RF system. when use the PA12 pin which is the one for the ir receiver can't compile it this si the log.

Any update on this issue?

Thank You.

Hi,

I had the exact same issue, and the following solution by SuperXL2023 works perfectly. Thanks !

[appleimperio]

@flohav thank you it worked

[RF197]

Thanks a lot, this worked for me as well (on a BX chip)!

[raufaser]

@SuperXL2023 Thanks a lot. It worked.

[Jaco1990]

@SuperXL2023 the solution worked for me aswell

[flohav]

Do you know how to apply this fix to Home Assistant Esphome? I couldn't fine the correct file to modify...

Do you know how to apply this fix to Home Assistant Esphome? I couldn't fine the correct file to modify...

A temporary fix was included in release v1.6.0. At the moment the only way to use this fix in Home Assistant and ESPHome is to add the following lines to your board declaration.

rtl87xx:
  board: ${board}
  framework: 
    version: dev

[kuba2k2]

Or you can probably use version: 1.6.0 Let me know if it works fine.

[flohav]

It works fine, I used version: dev, updated via Esphome on HA and no issue at all.

Another issue however, since a few months I can't get any value from my HLW8012 whereas it used to work. But that's another issue I guess.

Where can I find this .esphome folder?

I have a simple esphome folder that contains the yaml files

[olivluca]

Shouldn't this issue be closed now that PR #282 has been merged?

[olivluca]

And wouldn't it be better to use a similar solution to the beken-72xx (i.e. switch the edge in the interrupt handler)? https://github.com/libretiny-eu/libretiny/blob/9114bc4c4961ab38ea41a1fdf21ec79eb97d9254/cores/beken-72xx/arduino/src/wiring_irq.c#L54

[kuba2k2]

Yes, it would be better to have an actual solution, instead of the "workaround" which #282 is. This is perhaps why this issue is still open.

[olivluca]

I've ordered a smart plug, when it arrives if I manage to open it and it has this chip I'll see if I can implement a proper solution.

[olivluca]

Well, no joy, the aliexpress lottery sent me a plug based on the LN882HKI chip. Is that supported by libretiny or my only option is openbeken?

LN882HKI support was recently added to ESPHome via LibreTiny & PR though there may be some bugs with compiling as boards get straightened out.
