That likely uses the cloud connection, so not related here. Why don’t you use the regular web app?
This one connects using the same method as the mobile app
Thank you very much! That worked!
But, it is weird that I cannot access it locally, don’t you think?
It should be possible, but you’d first enable a local account?

(Sounds simple; however, this functionality is just introduced a while ago, until then it was impossible to access any Homey locally 
)
The actual HSHS IP address you’ll need to use, can be found here

at the ‘System Information’ part.
It did work! Thank you so much!!!
I just posted a question on the Zigbee routing topic about ZigBee existing routers. If you could please help me on that one as well, I would appreciate it.
Thanks!
