Scenario:

Device running with Emulation and HueBridge enabled.

When trying to control the device directly using Alexa and the exposed emulated hue device, this fails on 5.13.0. Rolling back the firmware to 5.12.0 without any configuration changes, and it works again.

Console Log from 5.12.0:

07:36:01 HTP: Hue API (/wTmwJE31i4yBe11Dx5epWo0E54NjKf2m36ZkU8tb/lights/1/state)
07:36:01 HTP: Hue POST args ({"on": true})]
-device turns on-

Console Log from 5.13.0

07:36:13 HTP: Hue API (/wTmwJE31i4yBe11Dx5epWo0E54NjKf2m36ZkU8tb/lights/1/state)
-alexa resports device not responding-

Thoughts

I've looked at sonoff/xplg_wemohue.ino, and the changes in 5.13.0 look nonconsequential...

Most probably related to #2414.

As a workaround you could try to compile tasmota 5.13.0 with core version 2.3.0 which was used with 5.12.0 too.

@arendst I have recompiled Tasmota 5.13.0 against core version 2.3.0, and can confirm that this resolves the hue bridge issue. Good spot, thank you.

This resolves the issue for me.. as long as I remember to change the target platform in the next release..

[acrelle]

Workaround was to edit platformio.ini as follows:

platform = [email protected]  ; v2.3.0
;platform = [email protected]  ; v2.4.0

I.e. comment out the second line, and remove comment on the first line.

Same issue for me on 5.13.1 but I have not recompiled to as just upgraded ota. Switching to WeMo works though and the Alexa app lets you redefine WeMo switch as a light, so this is an alternate workaround.

[acrelle]

Potentially resolved as this is now standard in v5.14.0 3ad1f43b78f3e0f547794cfb853898579af8352c ?

[arendst]

Yes. The released binaries should be available any minute now...

Thank you @arendst !
