The question is about groups scenarios
- 
The question is about groups, in fact these are scenarios. The question is how to call (enable or disable) a group from external sources? For example, from a node, sensor or using voice control?
 - 
@Clone-Tv to call the group from external, you have to use API from MyController. We do not have direct options
 - 
@jkandasa
Wouldn't it bother you to give a solution with an API? control through an arbitrary mgtt topic is desirable, although any other options are interesting. I looked at the page with the description of the API but did not see direct HTTP links to control .. or I looked wrong? - 
@Clone-Tv Simple solution would be accessing the API directly.
To turn ON
- POST https://your-mc-host-or-ip:8443/mc/rest/resources/group/on
 - Payload:
[3]or[3,4]- group id or group ids
 
 
To turn OFF
- POST https://your-mc-host-or-ip:8443/mc/rest/resources/group/off
 - Payload:
[3]or[3,4]- group id or group ids
 
 
IMPORTANT: For all the requests you should include
authorizationheader as follows,authorization: Basic YWRtaW46YWRtaW4K- To get base64 auth string:
 
# Format: username:password $ echo "admin:admin" | base64 YWRtaW46YWRtaW4KYou can get the group id by clicking the details of the group. on the address at the end you can see the group id.

Thanks for your reply, this method will do. Is there no way to bind groups to mgtt topics?
 - 
@Clone-Tv No, we can not control with MQTT
 - 
how to use scripts in groups? where to add the name of the script file? what value should I use to turn on and off?

 - 
@Clone-Tv looks like there is bug. Group will not support for
Script - 
it's a shame, it's a pity that there is no such possibility ..
