I have a recurring issue with the RCD on my consumer unit "tripping" so in order to protect my NASs and more importantly the music on them I've been researching various UPS models which could gracefully shut down the NAS (Synology DS716+) which I believe can be configured to alert me to an outage if away on business, maybe also keep the HUE lighting bridge & modem/router powered on long enough for me to set the lights appropriately until I'm home (some will be strategically placed around the house in ceiling fittings on the lighting circuits which are unaffected when the RCD trips). The security element is important as I've been burgled on 2 of the occasions the power was out and the house in darkness whilst I've been away.
I realised that much as I appeared to be finding a technical solution it may be better to get to the root of the problem instead and that's what made me think of asking what the best approach might be here as I've seen some extraordinarily technical conversations about power here on occasion.
I'm also considering whether to put the NAS on a UPS which notifies me when the ringmain circuit is down and put then BT Smart Hub and Hue bridge on the lighting circuit as they only draw under 40W between them? this way when I get an alert the NAS is shutting down I can look remotely if the lights are still on to see if it's just the RCD and ask a neighbour to reset it. Even without the notification the odds are the RCD will be the issue so 90% of the time the lighting schemes & timers will keep working.
I accept I will probably need to engage the services of a qualified electrician but I would prefer to avoid paying a call-out charge just to be told they can't test for intermittent problems. so if you can offer any advice or someone has had a similar experience they managed to resolve I'd be grateful to hear.
