Frequently Asked Questions
Do outdoor smart plugs work with 5GHz Wi‑Fi?
Most outdoor smart plugs in this guide require 2.4GHz Wi‑Fi only. Check your router settings—if you have a combined dual-band network, either enable a 2.4GHz SSID or create a dedicated 2.4GHz network for setup.
What IP rating do I need for string lights on a covered porch?
For a covered porch where plugs are sheltered from direct rain, IP44 (splash-resistant) is usually sufficient. If the plug will be exposed to driving rain or an open yard, choose IP66 or higher for better protection.
Can I dim any outdoor string lights with these plugs?
Dimming works only with compatible dimmable bulbs and LED string lights. Check bulb specifications—some pre-wired string sets use integrated drivers or transformers that aren’t dimmable with a plug dimmer. When in doubt, use dimmable LED bulbs or confirm the string-light manufacturer’s compatibility.
