Smart Home — FAQ
What dB alarm level is actually loud enough?
90dB works for same-room alerts but won't wake you from deep sleep across the house. 100dB reaches adjacent rooms reliably. 120dB penetrates walls and floors, making it the safest choice for whole-home protection. We recommend 120dB for basements and utility rooms, 100dB for bathrooms and kitchens.
Do I need IP66 or IP67 waterproofing?
IP66 handles heavy splashing and jets—perfect for washing machines, sinks, and water heaters. IP67 survives temporary submersion, ideal for basements that flood. For most homes, IP66 suffices and costs less. Choose IP67 only if your space actually floods; it's overkill for simple drip detection.
Can I use a smart leak detector without a hub?
Yes, most smart sensors work as standalone alarms without hub connectivity. You'll get the loud local siren but no phone alerts. The PILSAMAS unit we tested functions perfectly solo. Add a hub later if you want remote monitoring. This flexibility lets you start basic and upgrade without replacing hardware.
How long do batteries typically last?
Our tests showed 6-12 months depending on alarm frequency. High-quality alkaline batteries lasted 8-10 months in normal conditions. Lithium batteries extended life to 12+ months but cost more. Monthly testing is critical—weak batteries cause silent failures. Replace annually during daylight saving time changes as a reminder.
Will a gas detector find water leaks too?
No, gas and water detectors use completely different sensor technologies. Gas detectors identify combustible molecules in air; water detectors measure electrical conductivity between probes. Using the wrong type creates dangerous false security. Homes with gas appliances need separate gas detectors near furnaces and water heaters.
How many sensors do I need for my house?
Place one sensor per water source: water heater, washing machine, dishwasher, refrigerator ice maker, under each sink, and near toilets. Add basement and utility room coverage. Average 3-bedroom homes need 5-7 sensors. Start with high-risk areas if budget is tight, then expand. Multi-packs save 40% versus buying individually.
