But the page switching notification appears

@tbbear Please tell me if I can use notifications to update my sitemaps in this module?

I apologize for my English. I have a smart home controller that can display the relay status on an HTTP request
Example:

This response means that port 22 of the relay is disabled.I want to integrate my system into Magic Mirror to see the value of the relay. Thank you in advance

Can I use this module to manage MMM-pages?

@AxLed dear friend, please tell me why when you select “News (mehr/weniger Details)” and double-turn the encoder, the browser opens with an error

Please tell me if I can place different duplicates of the module on each slide with different menu items for navigation on the slides?

I can not get my chat id

Does this module support Russian?

Does this module support Russian?

Дорогой @Sean, прошу вашей помощи!
When starting MagicMirror MMM-Widget it starts automatically, although I have a MMM-Carousel installed and I did not specify the MMM-Widget in the configuration, after switching to any slide the widget disappears. How to fix this error?
