Amazon Echo ESP8266 control, with natural speech commands

Perhaps I am not so smart as you are.
But but what I must say, the “Wemo Emulator” (the Belkin Wemo) that you used in your first project ,fauxmoESP ,espurna ,Espalexa ,Tasmota and a lot more all are present thanks to Aruna Tennakoon " kakopappa ".
all the hard work was done by kakopappa.
now with SINRIC also from kakopappa you can control

TV / Speaker

Alexa.PowerController
Alexa.PlaybackController
Alexa.InputController
Alexa.Speaker
Alexa.StepSpeaker

Window Shutters

Alexa.PowerController
Alexa.ChannelController
Alexa.PercentageController

Thermostat

Alexa.PowerController
Alexa.ThermostatController
Alexa.TemperatureSensor

Switch

Alexa.PowerController

Light

Alexa.PowerController
Alexa.ColorTemperatureController
Alexa.ColorController
Alexa.BrightnessController

and now with GOOGLE HOME
you can check my post

@chrome1000 i gave up trying the routines.On a separate issue,i followed the tempory fix for light ON in Alexa app, changed the text like it said but lights still turn on in Alexa app when i enter the devices page,any ideas?

@jasperdog Yep. It started with an Alexa app update several months ago. However, since I typically use either voice control or Blynk, It’s a pretty rare occurrence.

here’s a code that i wrote for using a 4channel relay board. i have not modified it but you could just modify this code. this works using an easy to use sinric skill. since i am terrible at coding. Pardon ME.
it also has some other stuff for controlling my ac and the temerature

@Sai_Khurana
can I have your QR code.
Thanks

Hey @jasperdog

Just out of curiosity, are you using the early code, based on the “WemoManager” library? If so, try the newer version that uses the “espalexa” library. My devices that use the newer code seem to work just fine with all aspects of Alexa, including routines. You can find the newer version above, in my April 2, 2018 post.

i am using the WemoManager library, i’ll try your suggested library now.

it works @chrome1000 , thank you, i notice now that the device is a light and not a switch and cannot be edited as a switch unlike the wemomanager option, it makes no difference to the operation of the sonoff though. The routine works as does the Blynk side too. Many thanks again.

I’m glad we got that resolved. The real beauty of using the espalexa version is that Alexa will accept both ON/OFF and analog level commands. You can ask her to “turn on the fan,” or you can also ask her to “turn the fan on 25%.”

@chrome1000 i just tried reflashing a second device (different blynk token). alexa discovered it but lost the first device, any ideas?
is it to do with the following line needs changing other than the obvious “bedroom” name?

espalexa.addDevice("Bedroom", UpdateBedroom); //Parameters: (device name, callback function).

both devices work in blynk

pin is
const int OutputPin = 12;

@chrome1000 so in conclusion, it appears i can only have one instance of a device using the espalexa sketch, i can even turn one device off and the other appears and vice versa but not both together, different tokens used, different names used?

@jasperdog I’ll try to figure it out.

thanks @chrome1000
just to be clearer, i don’t use wifi manager in my sketch and i have my own local Blynk server, so my sketch is a bit more adapted than the espalaxa one that you showed. although everything bar the wifi manager exists in my sketch.

@jasperdog Great news! You just need to update your espalexa library. I just tested my system with 3 devices running concurrently. Here’s the link:

great i will try it now, just for clarity, do i need to change this line name for each device?

I’m not sure. Just for clarity with my own tests, I did give each device a different name.

ok my first attempt is in progress, will update you in about 15 minutes

first device reflashed and found as bulb in Alexa App, just reflashing second device.using different name.

@chrome1000 unfortunately it didn’t work for me, in fact the second device did not come online in Alexa or Blynk, not sure why but was too tired to continue, will explore later today.

@chrome1000 i also found that using the new library, does not sync/update the buttons in the Blynk app. i only managed to connect one device to Alexa and Blynk but still no sync with buttons, i didn’t modify my sketch at all from using the old espalexa library, so i can only imagine that these issues pertain to the new library, i think i’ve exhausted all testing now and will revert back to using the original WemoManager library and sketch, all be it without being able to create routines, but it’s no big deal because it’s just as easy to say “Alexa” and whatever you want. Many thanks for your continued help, it is appreciated.
