I use two such switches a year back, but have abandoned them.
They were very hard to include (had to do it 10cm from controller) and after a few months they was not seen by the controller anymore. Happened 2 times.
Read of my struggles here.
If you still have possibility to return them do so.
If not, they could be usable with direct association.
I ended up using this instead. A delight to include, does not drop connection and always work on first press.
