Can't connect to any FHEM instance about mmm-fhem HOT 3 OPEN

Have you tried to setup your host with username and password? Maybe this could solve your problem: #2

Otherwise you have to debug the js code. If you want to debug the code you can use the electron dev tools. Just start the magic mirror with "npm start dev". This will start electron with opened dev tools. In the "Sources" tab you have to navigate to modules/MMM-FHEM/MMM-FHEM.js. Search for "sockeNotificationReceived: function...". At this point you can start to debug your fhem response.

I have the same issue. I cannot connect to any FHEM instance. The module is not displaying anything. I can see it in the browser tools but no data is ever shown with any config connecting to any FHEM instance.

Any help (maybe someone posting his working config) is appeciated! :)

the Fix for you`r Problem might be:

Disable csrfToken

to test the module you can insert in the config 'header: 'Smarthome',' to see if the module is pop up an header if not the problem might be somwere else.

as an last option you can try attr WEB.* csrfToken none
