[NodeRed][Alexa] Read Temperature

[emme]

Ciao,

I found a way to have Alexa access Domoticz Temp sensors and speaks.

To do so you will need:

• Alexa (of course)
• NodeRED
• node-contrib-alexa-home-skill Installed
• NodeRED skill enabled
• A Registered account on https://alexa-node-red.bm.hardill.me.uk/

there is no cloud... the web site it is only needed to create device aliases, but all requests are only locally executed
than the flow will looks like the following

dzAlexaTempFlow.jpg (42.16 KiB) Viewed 4624 times

each device has been configured on the web site, than it is converted into a HTTP request and send back to alexa with the T value

The command is:
"Alexa, what's the temperature in <device>"
"Alexa, quale è la temperatura in <device>" (in italian )

it works like a charm!

[sazubel]

can you post the node-red code for this please?

[emme]

SURE!
here it is
change the node that reflect the assignment between the device and the domoticz IDX (will find mine inside)

Code: Select all

Are you guys still able to use it? I can't find a way to make it work

[gizmocuz]

I am using Sinric

I wanted to have alexa read the energy and outdoor temperature sensors vocally , the system that @emme uses in the post above would be interesting but it doesn't seem to work ; I also put debugs in the process but it doesn't seem to activate,i don't want to use cloud services .I have node-red 3.0.2 on docker [/attachment]

For me the flow works perfectly. Have you password on your domoticz? If so, try to put it into "dz HTTP API" node in "use authentication".
If not, try to put a debug node after each node and tell us what messages you have.

@zuputrus,
I solved by having nodered read the MQTT messages .Thanks
