I installed the Lidl smart home app and tried to install the Lidl/Silvercrest motion sensor. No luck, every time I get the error and try again message.
If you are able to use a computer while doing so you can also enable the developer console in your browser where you are able to get some extra info regarding why the device does not pair nicely.
Thanks for your reply.
Using the developer portal on my computer I succeeded to connect the sensor after a few tries. I will add the second one and try the functions tomorrow and will let you know the results.
