Threads appear again and again in the forum in which Shelly's problems in the network are reported.
In the end, there is usually the realization that the problem is not the Shelly itself, but rather the network hardware used, e.g. does not support the required protocols.
This plays a crucial role, especially for users of higher-level systems such as FHEM, ioBroker, etc., especially when e.g. coap or coiot is used.
We recognized the router as a possible cause quite early on and put together a list of incompatible routers here.
Furthermore, the following network components have now been determined to be incompatible:
DLAN:
- AVM Fritz Powerline 1260 E
- Devolo 200
- Devolo dLAN® 550 duo+ (Thanks to user ekech)
Annotation:
Anyone who finds or knows threads with other incompatible devices could please send me the link via PN (conversation) so that we can compile a complete list here, as we did with the routers.
Thank you for your support.
