Enerwave RSM2 buggy?

Hi,

I installed the enerwave on 2 locations connect around 15 led downlights to each, now the problem is they cannot be controlled via app even after recognizing and connecting, and also dont work manually, some times they will start working, other time i cannot put them off or some times cannot turn them off, if i open the board and knock the relay a bit hard they will start working manually, then when i close the box they again stop working, is this buggy relays? my rsm 1’s work perfectly fine, i also put eric’s device handler, which is all over this forum
thanks
