Not 100% sure so you will need to do some searches but the aqara stuff does not follow the zigbee standards 100% so you need to be careful what devices you use as routers if you want a stable mesh. The sensors you can do work arounds on to some extent, but if a router is breaking standards and not passing data on you can not work around that. As mentioned do some reading on what routers people find work well and build up a mesh to devices that are known to work well.
EDIT: @Constantinos_Contis I stumbled back onto some info on this which lists some routers that work with aqara. If you have a CC2531 stick you can program these to be cheap repeaters/routers.
