[Wireless shock/vibration sensor with Door Contact]

Good morning, 

I've bought a GalaxyFlex and a RF Portal from Honeywell which work like a charm

I would like to add some Wireless shock/vibration sensor with Door Contact in my house.

I've bought the "Honeywell Le Sucre Wireless Shock Sensor with Contact White" ( Model: SHKC8M ), but it's quite big. I would prefer something smaller, more discreet , like the Honeywell Wireless Door/window compact magnetic contact Brown ( Model: DO800M2 ), but with the shock sensor feature

Could you advise me another product (shock + contact) which would be compatible with the GalaxyFlex ?

Thanks in advance for your help

Cedric
