Ops. I cloned the master branch.philchillbill wrote: ↑Saturday 23 November 2019 18:13 Oh boy. One of those days. Sorry. Does it work now?
Edit: I see the dev branch in the original post. Not sure why you think I linked the master.
Hello, thanks for your support. I did the test yesterday but getting this error:philchillbill wrote: ↑Sunday 24 November 2019 8:53 It’s called api_reportState in the original.

Thank you! I updated the AlexaSmartHome.py deployed in the Lambda as you suggested and it works great. Linking the skill with my account, I'm able to obtain the CODE.philchillbill wrote: ↑Sunday 24 November 2019 20:02 I'll take a proper look at this tomorrow. Maybe the easiest thing to do it to just create a single file for reportstate.py that has all the stuff it needs from the imports locally so it does not depend on external files. Sorry for this. I extended my Alexicz to do way more than just Domoticz from within a single skill and that's why my code is now so different.
But the AcceptGrant code does work ok for you? That will always be needed in the Lambda.
On https://developer.amazon.com/alexa/console/ for smart home I'm using it-IT locale. Do I need to switch to en-US? In that case, the Alexa will accept commands in Italian?philchillbill wrote: ↑Monday 25 November 2019 8:55 Remember that, as per https://developer.amazon.com/docs/devic ... faces.html, only the en-US and en-CA locales support contact and motion sensors. What locale are you using for Alexicz?
Ok, let's work to anticipate amazon when the feature will be available in Europe then!philchillbill wrote: ↑Monday 25 November 2019 12:22 Contact sensors and Motion sensors only work in US English, not even British. So Italian is really a no-no, I'm afraid.
No I'm referring to the body request created by the api_reportState. To understand why it is failingphilchillbill wrote: ↑Monday 25 November 2019 13:48 You mean to request Amazon to implement it? They already know people want it - we are not the first requesting this.
My request looks like this:No I'm referring to the body request created by the api_reportState. To understand why it is failing

Is your Domoticz URL as entered in the config JSON file a https one?I’m getting an error of "urllib.error.URLError: <urlopen error EOF occurred in violation of protocol (_ssl.c:852)>"
Hi, with this will I be able to ask alexa if eg a light is turned on or off. I'm using philiphs hue. Taphilchillbill wrote: ↑Tuesday 26 November 2019 21:32 To make sure you are reporting EndpointHealth, the following changes need to be made to the Lambda files:
In AlexaSmartHome.py. add:
At the top of the method serializeProperties, under the 'for prop in self.propertiesSupported():', after 'prop_name = prop['name']', addCode: Select all
@INTERFACES.register('Alexa.EndpointHealth') class AlexaEndpointHealth(AlexaInterface): def name(self): return 'Alexa.EndpointHealth' def propertiesSupported(self): return [{'name': 'connectivity'}]
Finally, in DomoticzHandler.py, close to the start of the file and immediately under 'class DomoticzEndpoint(AlexaEndpoint):' add the following:Code: Select all
if prop_name == 'connectivity': prop_value = { 'value': 'OK' }
After doing that, do a device discovery to add this new capability to all your endpoints. Without it, change reports work in routines but you cannot ask if a door is open or closed. With it, you can ask "Alexa, is the front door open" and get a spoken response "Front door is closed".Code: Select all
def __init__(self, endpointId, friendlyName='', description='', manufacturerName=''): super().__init__(endpointId, friendlyName, description, manufacturerName) self.addCapability(AlexaEndpointHealth(self, 'Alexa.EndpointHealth',[{'name': 'connectivity'}])) self._device_ = None
Thanks for the reply. Yes sorted it now, I had rebooted domoticz when adding a user and it hadn't fully restarted. Well at least I think that's what it wasphilchillbill wrote: ↑Wednesday 27 November 2019 8:03Is your Domoticz URL as entered in the config JSON fike a https one?I’m getting an error of "urllib.error.URLError: <urlopen error EOF occurred in violation of protocol (_ssl.c:852)>"
Nope. Not yet at least. Only works for contact sensors. Amazon limitation.
