Thanks for your help!
I had a look in the logs which were inconspicuous. But when I had a look in the console I found the following:
:8080/modules/netatmo/q.min.js:1 Uncaught TypeError: Cannot read property ‘dashboard_data’ of undefined
at Class.renderAll (:8080/modules/netatmo//netatmo.js:106)
at e (:8080/modules/netatmo/q.min.js:1)
at :8080/modules/netatmo/q.min.js:1
at o.d.promiseDispatch (:8080/modules/netatmo/q.min.js:1)
at :8080/modules/netatmo/q.min.js:1
at b (:8080/modules/netatmo/q.min.js:1)
at a (:8080/modules/netatmo/q.min.js:1)
at s (nunjucks.min.js:4)
at o (nunjucks.min.js:4)
at n (nunjucks.min.js:4)
I have no idea what’s going on…
