Hi, Looking at adding a night light at my parents for their landing and also bathroom (which at their age is the main reason they might wake up at night). I'm looking for a low level panel light that I can add to a stud wall and also maybe an LED strip to add under the bathroom furniture, which is about 1800mm of cabinets. Any idea what sort of watts I should be looking for that is not too bright but does the job? Also, looking for a sensor to turn them both on when someone walks out of the bedrooms onto the small landing (1m x 3m approx). My sparky mate reckons a ceiling sensor which can be fitted centrally so it covers all 3 bedroom doors as well as the stairs. Would I be looking at a PIR or is there something else to consider? Cheers Vijay

We have numerous cupboards in our build and I have fitted sensor lights as it seemed a good idea at the time but now I have fitted the doors the lights come on as we walk past. I have reduced the sensitivity of the lights and they still turn on. Some of the doors fit into a rebate and as of yet are not able to be fully closed as there are no handles on but had a quick test by holding shut and the lights still come on. I think with the large gap at the bottom for the MVHR this lets the movement of somebody walking past be detected by the sensor. Some of the doors just close together so there is a gap between them and this is worse. So apart from having to reduce the gaps under the doors (not sure what I will do with the doors coming together) has anybody any ideas of what we can do or are we destined to have lights turning on as we walk past them!! TIA

Just trying to sort light switch locations and if we decide to have motion sensors in d/s toilet and long corridor with three rooms off it do I still need light switches adjacent to rooms as back up or can I do away with them completely? TIA

I am finalizing my MVHR specification, having to self install, as there are no contractors who will fulfill my requirements (no surprise). I will be fitting 2 x Brink Renovent Excellent 400 Plus units with Ubink ducting. I have discovered that I can get internet connections for the MVHR units so I can do away with the 3 position switches/remote controllers and use a web interface/ app to control them. I will be fitting RH sensors in the extract ducting to auto boost the system, but I was wondering if it is worth including CO2 sensors also. The theory being that I could run the system slower than the building regs extract requirement with the CO2 ramping it up if required, the same as the RH. The building Regs extract requirement is the key as I have a large house 439m2 so this trumps any wet room extract rate. I have the following planned extract rates: 0 150m3/h Very low level for un-occupied periods. 1 320 m3/h lowest keeping room extract rates at BR requirements 2 495 m3/h floor area extract rate to comply BR 3 570 m3/h Boosted keeping the units within PH standards My original plan was to run the units at 1/2, depending on house occupancy levels with the RH boosting up to 3 as required, however with CO2 sensors I should be able to just let the system do it's thing. Do they work and are they worth it? (approx. £700 extra on a £10,000 equipment spend) -
Does anyone have any experience of embedding moisture sensors in the substrate of a new flat roof, in order to detect future leaks? Or any suggestions of how it might best be done? Not that leaks should happen for many years, but if/when they happen, it would be cool to get an early warning, rather than waiting until water damage becomes visible...
