Hi during the past 3 years I have now had 3 F411/2 replaced because they become unreliable. This seems to happen on lighting circuits with low watt LED's. They switch on fine but I cannot switch them off either with the wall switch or even directly on the actuator. I find if I power cycle the bus it sometimes works again for a while but eventually even this does not work.
Is this a regular issue or I am just unlucky! I am gradually changing all my lights to LED so I would like to have a solution.
