Idea Motion Sensor

[luccas222]

I'm very new to programming, and I don't think I will be able to do this, but I'm thinking that if you modify your emulator to not only be a HUE light but to appear as a HUE Motion Sensor... can Alexa trigger routines by sensor state? I know that Phillips have an open source api for sensors, but I don't understand how to make your code to implement it and be recognized by alexa as a motion-sensor. Maybe you already tried this.

BTW I managed to mix your code with some other to get the status of the sensor-pin, and also to turn on/off a light manually with a touch sensor. But even when alexa knows the status and shows me that status in the app, I can't trigger a routine with the created device.

Sorry for my bad english, I'm from argentina. I will paste my code for you here:

So basically... 1- Can you tweak/update your library to manage Motion Sensors? 2- Once Motion Sensor is recognized as is... can Alexa trigger routines with it?

I found yesterday a Sinric Pro, and it works like a charm, but it works like a HUE hub.

@luccas222 can you share a link to what you've found?

I've added code to my light switch device that sends an update to Alexa. What I need to do is make it a "state" device. That is to say a device that reflects open or closed for instance. BUT the skill would also need to have like a "triggered" state also. Does that make sense?

[luccas222]

Hi Mike, I managed to mix some code and make the app know if the device is on/off, but still that doesn't make alexa to trigger a routine. Right now and "for the moment", I will use the service of SinricPro, you can have 5 devices with the free account. The URL is https://sinric.pro/.

I really don't know how they managed to make it work...

[mharmon12]

I used sinric from an instructable and it didn't have ability to know what state it was currently in OR update Alexa if the state changed at the device as a Smart switch would.

This Espalexa gets me to 95% of where I want to be with my apps. Once I hack the ONOFF functionality then I'll be 98% because then I just need a sensor BUT I could spoof that with a switch.

@luccas222 What do you mean by, ..."doesn't make Alexa to trigger a routine??

[luccas222]

Hey Mike, sorry for my bad english... I will try to explain better. YES "Sinric" is not able to trigger Alexa routines, but "Sinric Pro" is.

What I mean is that you are "not able" to create an alexa routine based on the sensor state. Not even to make alexa to say something. I was searching for a way of making alexa to manage sensors and trigger routines, acting as an alarm.

EspAlexa and FauxmoESP are great! but I they lack of "something" and I really don't know what!! to make the devices to work with alexa routines.

If your read more in this repository I think the author answered to other similar issue about what he thinks the problem is.

I just want to help the way I can, but to me, not being a developer, the only way to help is to send good vibes and my findings.
