Fil - regarding Luron with beo4 Lutron grafikeye series for beo is intended for new build or renovation - as already sataed you can see the range at http://www.onidserv.com/lutronshop/group/701/ if you have a 3 gang switch and you want to upgrade to dimming via your beo4, then you could fit the grafikeye gbo-3103 unit - it would need some building works

godoz you should be OK with your beo4 with the lutron grafikeye products. be sure to order the GBO3100 range or EGBO wall stations you can see all lutron BEO grafikeyes at http://www.onidserv.com/lutronshop/group/701/ or google lutron beo hope this helps nick
