Your weather app says it's sunny, but it's raining in your backyard. Why? Because generic forecasts come from airports miles away. In 2026, hyper-local weather tracking is the only way to know what's actually happening at your home.
Two hardware systems dominate this niche: The modular, elegant Netatmo Weather Station and the all-in-one, futuristic Tempest Weather System. One relies on traditional mechanical sensors, while the other uses ultrasonic waves and haptics to measure the elements with zero moving parts. Which engineering philosophy is superior? Let's analyze the hardware.
The Hardware: Moving Parts vs. Solid State
This is the most radical difference in the industry.
Netatmo (The Modular Classic)
Netatmo is a collection of cylinders.
How it works: The Rain Gauge uses a "tipping bucket" mechanism inside (it physically rocks back and forth when water fills it). The Wind Gauge uses ultrasonic transducers.
Maintenance: Because the rain gauge is a physical bucket, it gets clogged with spider webs, leaves, and bird poop. You must clean it regularly to keep it accurate.
Tempest (The Future Tech)
Tempest is a single white unit that looks like a lighthouse.
How it works:
- Rain: It uses a Haptic Rain Sensor. It "feels" the vibration of raindrops hitting the top dome. It can distinguish between light drizzle and heavy hail instantly.
- Wind: It uses Ultrasonic Sound to measure wind speed in the gap between the roof and the base.
Benefit: Zero moving parts. Nothing to clog, break, or wear out. It is virtually maintenance-free.
Power & Connectivity: Solar vs. Batteries
Tempest: Completely solar-powered. It has panels wrapped around the base. It charges during the day and runs on a capacitor at night. It communicates via a long-range radio (900MHz) to a small hub inside your house, allowing you to place the station up to 1000 feet away.
Netatmo: Uses standard AAA batteries. You have to climb the ladder to change them every year. It connects via Wi-Fi, which can be tricky if your Wi-Fi signal doesn't reach the far end of your garden.
Smart Home Integration: Automation
Why do you need a smart weather station? To control other hardware.
- Rachio Integration: Both stations talk to smart sprinkler controllers. If Tempest detects rain, it tells your Rachio sprinkler to skip watering today. This saves thousands of gallons of water.
- Indoor Air Quality: Netatmo comes with an Indoor module that measures CO2 and noise levels. Tempest is purely focused on the outdoors.
Comparison Table: 2026 Specs
| Feature | Tempest Weather System | Netatmo Weather Station |

| Power | Solar (Built-in) | Batteries (AAA) |
| Lightning Detection | Yes (Up to 40km away) | No |
| Price | ~$330 (All-in-one) | ~$350 (If you buy all modules) |
FAQ: Lightning & Wind
Does it really detect lightning?
Yes. Tempest has an EMP sensor that detects the electromagnetic pulse of a lightning strike. It alerts you instantly: "Lightning detected 10 miles away." This is a killer safety feature for pools and outdoor sports.
Which wind sensor is better?
Ultrasonic (Tempest) reacts faster to gusts than mechanical cups (traditional). However, Netatmo's ultrasonic sensor is also excellent, but it requires a separate purchase.
Buy Netatmo if: You care deeply about indoor air quality (CO2 levels) as much as outdoor weather, and prefer a modular system you can expand slowly.
Buy Tempest if: You want the absolute latest "set it and forget it" technology. The solar power, lightning detection, and lack of moving parts make it the ultimate hardware for weather geeks.
