Your outdoor smart plug just stopped working after getting wet, and now your holiday lights, security cameras, or pool equipment won’t turn on. This is actually one of the most common smart home emergencies, especially during rainy seasons, and fixing it is usually straightforward if you know what to do.
Step-by-Step Fixes
Step 1: Power Down and Dry Everything
First things first – turn off the circuit breaker that controls your outdoor outlet. Yes, right now. Water and electricity are a dangerous combination, so safety comes before troubleshooting. Once the power is off, unplug your smart plug completely and bring it inside if possible. Use a dry towel to wipe down any visible moisture on the plug’s surface.
Step 2: Check Your Wi-Fi Connection
While your plug is drying, open your smart home app (whether it’s Kasa, Smart Life, Amazon Alexa, or Google Home). Look for the device in your app’s device list. If it shows as “offline” or “unavailable,” that’s actually good news – it means the plug might just need to reconnect once it’s dry. Try refreshing your device list by pulling down on the screen or tapping the refresh button.
Step 3: Inspect the Weatherproof Seals
Take a close look at your smart plug’s rubber gaskets and weatherproof covers. These are the rubber rings around the plug prongs and any protective flaps over buttons or outlets. If they look cracked, torn, or weren’t properly seated, water probably got inside. Gently press on these seals to make sure they’re sitting flush against the plug body. If you see any damage, you’ll need to replace the plug.
Step 4: The Rice Trick (Yes, Really)
If your plug got seriously soaked, place it in a sealed container with uncooked rice for 24-48 hours. The rice absorbs moisture from inside the electronics. This works best for plugs that don’t have obvious water damage but just aren’t responding. Make sure the plug is completely unplugged and the container is airtight. After the drying period, shake out any rice dust before testing.
Step 5: Factory Reset Your Smart Plug
Once your plug is completely dry (wait at least 24 hours), it’s time for a factory reset. Most outdoor smart plugs have a small reset button – you’ll need a paperclip or pin to press it. Hold the button for 10-15 seconds while the plug is connected to power. The LED light should flash rapidly, indicating it’s ready to be set up again. Open your smart home app and follow the setup process like it’s a brand new device.
Step 6: Test with a Different Outlet
Before assuming your plug is dead, try it in a different outdoor outlet or even a protected indoor outlet. Sometimes the issue isn’t the smart plug itself but the GFCI outlet it was plugged into. GFCI outlets (the ones with Test and Reset buttons) can trip when they detect moisture, cutting power to protect you from electrical shock.
Likely Causes
Cause #1: Water Infiltration Through Damaged Seals
The most common culprit is water getting past the weatherproof seals. Even plugs rated IP44 or IP65 for outdoor use rely on intact rubber gaskets to keep water out. Check for any gaps where the plug body meets the outlet cover, or where the cord enters the plug housing. If you can see daylight through any seal, water can get in. The fix is ideal for handy folks – apply clear silicone sealant around problem areas, but only after everything is bone dry.
Cause #2: GFCI Outlet Tripped
Your outdoor outlet likely has GFCI protection that automatically shuts off when it detects ground faults (often caused by water). Look for outlets with Test and Reset buttons – press the Reset button firmly until you hear a click. If it won’t reset or immediately trips again, there’s still moisture present. This situation is best used in conjunction with waiting for everything to dry completely before trying again.
Cause #3: Wi-Fi Signal Degradation
Rain and moisture can actually interfere with Wi-Fi signals, especially if your router is far from the outdoor plug. Wet walls, trees, and even heavy rain act like barriers to your 2.4GHz network. Check if other outdoor smart devices are also having connection issues. This scenario is not recommended when you need immediate control – consider adding a Wi-Fi extender closer to your outdoor devices for better wet-weather performance.
When to Call Expert Help
Stop what you’re doing and call an electrician if you notice any burning smell, see scorch marks on the outlet or plug, or if your circuit breaker keeps tripping even after everything is dry. These are signs of electrical damage that could cause a fire. Also, if your smart plug is hardwired (not just plugged in) or if water has gotten into your home’s electrical box, you need professional help immediately.
Contact the manufacturer’s support if your plug is under warranty and less than a year old. Many companies like TP-Link, Treatlife, and Govee will replace water-damaged units if they were advertised as weatherproof but failed in normal rain conditions.

Remember, outdoor smart plugs are designed to handle weather, but they’re not submarines. Most failures after rain are temporary and fixable with patience and proper drying. The key is acting quickly to prevent permanent damage while staying safe around wet electrical equipment.
