Alexa, Blynk and IFTTT help!

[newdos]

Hi Guys,

I have read all the thread on here re this subject and then had a go getting my alexa to operate a V pin in my existing Blynk app. I got it working quite quickly to enable me to switch my shed lights on via a voice command to alexa using applets in google IFTTT and webhooks. I got it to trigger a vurtual pin so that the app widget state changes when a voice command is issued.

Now here is the problem!! The ‘ON’ command works perfectly every time, so then I duplicated the command and changed the body text to a [“0”] to switch them back off with a new trigger line but I get a server error 500 when I try to voice command the lights off.

I dont get it the applets are identical(apart from the body change) and one works and the other doesnt!!!

Any help appreciated as normal.

Here are the 2 applets

Cheers Kev

@newdos Use GET without a body as:

ON syntax
http://blynk-cloud.com/auth_token/update/pin?value=1

OFF syntax
http://blynk-cloud.com/auth_token/update/pin?value=0

Try it in a browser first.

Covered at https://blynkapi.docs.apiary.io/#reference/0/write-pin-value-via-get/write-pin-value-via-get

Also sent you a PM.

HI Costas,

Weirdly it just started working today without changing anything !!! any idea what the server error was ?

And one of these days I will remember to remove my token DOH !!!

Cheers

Error 500 is a pretty generic server error meaning “there was a problem”.

Maybe IFTTT had a minor glitch.

[newdos]

OK cheers bud, but should I use the syntax you suggested or as it works is it ok to leave as is ?

Cheers

I am always tempted to leave things well alone when they are working.

That said GET is much easier to work with.

I would set up additional Applets with GET and have both available.
