Devices are discovered, but do not respond

[cg089]

SUMMARY

Amazon Echo detects all devices set up in node-red, but swtiching fails ("Das Gerät antwortet nicht" which may translate to "device does not respond")

ECHO DEVICES

Servera Echo Dot 1st and 2nd Gen

MODULE VERSION

0.1.10

Side note:
Node Red is in a different Vlan (Unifi). Firewall Rules allow all traffic to Home Assistant / Node Red on all ports. UDP Multicast enabled.
Echo devices are able to find all set up switches after I delete them in Alexa and look for them again.
However, switching the devices fail.

Alexa (and its VLAN) needs only to be exposed to your Home Assistant / Node Red IP. Be sure to verify your rules are correct and in the proper sequence (a drop may come before an allow). Alexa will only "see" your HA/NR on Emulated Hue, which is port 80. No need to expose or allow anything else.

Also, start with Alexa and HA/NR on the same VLAN. (ie: put one Echo device on your NR VLAN, do a discovery, then move the Echo to the desired VLAN.)
