Can someone please post some examples for HA-Bridge for Alexa?

Struggling to get the HA bridge to post commands to HASS. I know HA bridge is working as I also have a Vera setup in HA Bridge and that is working fine.

Interested in seeing some examples e.g. with dimable lights. I also read about an example where a thermostat was controlled via HA bridge (faking it was a light).

Below a non working example and really struggling what is wrong with it…(xxxx is of course Hass PW)

Ok , my bad. Wrong URL. Below is correct.

However still would love to see some examples. The light in this example is a dimmer and would love to see how it would work with a dimming value or thermostat.

I also would appreciate a sample of what to enter into HA-Bridge (4.1.4). To turn on a light, I use:

Many thanks!
