MMM-remote and hide all modules
- 
 Sorry if this has been posted before but have searched and have not found anything. I am using mmm-remote and are able to hide a module by using http://mymirror.domain/remote?action=HIDE&module=module_2_clock But I want to hide all modules. How do I type this. Have tried http://mymirror.domain/remote?action=HIDE&module=module_2_clock,module_4_calendar but this only hides one module. I want to make this work in Home Assistant and Alexa so I can disable all modules with one command and show a full screen background or weather instead.

 @Jopyth Maybe I have put this in the wrong place but maybe you are the one who can answer this.

 @planet4 This is not possible currently. Can you use multiple calls, i.e. hide all modules after each other? This would be a workaround. Or you could implement it yourself with a new action such as HIDE_ALLwithout too much work.

 @jopyth Thanks for your reply. Was able to solve it like this: (in a switch in home assistant) I can now say, Alexa, Hide all modules. /usr/bin/curl -O “http://192.168.0.XX:8080/remote?action=HIDE&module=module_2_clock” -O “http://192.168.0.77:8080/remote?action=HIDE&module=module_3_MMM-Skolmaten” -O “http://192.168.0.77:8080/remote?action=HIDE&module=module_4_calendar” -O “http://192.168.0.77:8080/remote?action=HIDE&module=module_5_calendar” -O “http://192.168.0.77:8080/remote?action=HIDE&module=module_6_calendar” -O “http://192.168.0.77:8080/remote?action=HIDE&module=module_7_currentweather” -O “http://192.168.0.77:8080/remote?action=HIDE&module=module_8_weatherforecast”

 @jopyth can you explain me how I can implement a HIDE_ALL? I’m very new in such things and looking for something like that. Want to be able to activate one module and hide all other for the time. Thanks
