Frequently Asked Questions

Does the YC9387(W) work with Weather Underground?

Yes! The YC9387(W) features built-in WiFi connectivity specifically designed for seamless Weather Underground and WeatherCloud integration. Once connected to your home WiFi network, your weather data uploads automatically every 16 seconds. You can view your station's real-time data from anywhere in the world using the Weather Underground mobile app or website. No monthly subscription fees are required—both platforms offer free personal weather station accounts.

How big is the display and can I read it from across the room?

The YC9387(W) features our largest 7-inch (17.8cm diagonal) colour LCD display, making it exceptionally easy to read from across the room. The high-contrast colour screen with adjustable brightness ensures excellent visibility in all lighting conditions. This is significantly larger than standard weather station displays (typically 5-6 inches), making it perfect for living rooms, home offices, or kitchens where you want weather data clearly visible at a glance.

What is the wireless range between outdoor sensor and console?

The YC1130 outdoor sensor communicates with the console at 868 MHz frequency with a maximum range of 150 metres (450 feet) in completely open space with no obstructions. In typical UK homes with walls, windows, and furniture, expect reliable transmission up to 50-100 metres. This range is more than adequate for standard residential properties including large gardens, detached houses, and even small farms or allotments.

Do I need to pay for Weather Underground or WeatherCloud?

No! Both Weather Underground and WeatherCloud offer completely free personal weather station accounts with unlimited data storage. Simply create your free account on each platform, obtain your unique station ID and password, and enter these credentials into your YC9387(W) console settings. Your weather data will then upload automatically with zero monthly fees, no subscription charges, and no premium membership required for basic features.

Can the outdoor sensor survive harsh British weather?

Absolutely. The YC1130 sensor is engineered specifically for permanent outdoor installation in all weather conditions. It carries an IPX4 weather-resistance rating and operates reliably in extreme temperatures from -40°C to +60°C, easily covering all British seasonal variations including freezing winters, hot summers, heavy rain, strong winds, and snow. The durable construction is designed to withstand years of continuous outdoor exposure.

How do I access my historical weather data?

The console stores 24 hours of historical weather data with hour-by-hour breakdowns that you can view directly on the 7" display. For long-term historical analysis, Weather Underground and WeatherCloud store all your uploaded data indefinitely in the cloud. Access detailed interactive graphs, trends, statistics, and comprehensive reports going back months or years through their web interfaces or mobile apps. You can also export your data in CSV format for custom analysis in Excel or other tools.

What makes the YC9387(W) better than cheaper weather stations?

The YC9387(W) is a professional-grade system with significant advantages: Extra-large 7" colour display (vs 3-5" on budget models), WiFi internet connectivity for remote monitoring worldwide, meteorological-grade sensors with superior accuracy (±1°C vs ±2-3°C on cheap models), longer wireless range (150m vs 30-60m), comprehensive 5-in-1 sensor array (vs basic 3-in-1), Weather Underground compatibility, firmware update capability, expandability to support 7 additional sensors, barometric pressure forecasting, and comprehensive UK warranty support. Budget models typically only display data locally with no internet features.

Is this the genuine UK version with full UK warranty?

Yes, this is the official UK version purchased directly from Youshiko Ltd, an authorized UK distributor registered in England (Company Number: 08629116). It includes a genuine UK power adaptor with 3-pin plug, full UK manufacturer's warranty, UK compliance certification (CE marked), and UK-based customer support. Internet time synchronization is pre-configured for UK time zones with automatic BST (British Summer Time) and GMT switching. All documentation and support are in English.

Can I expand the system with additional sensors?

Yes! The YC9387(W) console supports up to 7 additional wireless temperature and humidity sensors (Youshiko model YC80, sold separately). This powerful expandability allows you to simultaneously monitor multiple locations around your property—perfect for tracking temperatures in different rooms, greenhouse conditions, shed, garage, basement, attic, conservatory, wine cellar, or various outdoor areas. Each sensor displays independently on the large 7" screen with clear identification.

What batteries are needed and how long do they last?

The outdoor YC1130 sensor requires 3 x AA batteries (not included—we strongly recommend quality alkaline batteries like Duracell or Energizer for best performance and longest life). With quality alkaline batteries, expect approximately 12 months of continuous operation before replacement is needed. The console runs from the included AC/DC power adaptor with a CR2032 backup battery (included and pre-installed) that maintains time and settings during brief power outages.

Will this work with my home WiFi and broadband provider?

The YC9387(W) is compatible with standard 2.4GHz WiFi networks (802.11 b/g/n protocol). It works seamlessly with all major UK broadband providers including BT, Sky, Virgin Media, TalkTalk, Plusnet, EE, Vodafone, Now Broadband, and others. Important requirement: The station needs 2.4GHz WiFi and does not support 5GHz-only networks. If you have a modern dual-band router, ensure the 2.4GHz band is enabled (most routers have both bands active by default).

How accurate are the weather measurements?

The YC9387(W) uses professional-grade sensors with excellent accuracy: Temperature ±1°C (±1.8°F), Humidity ±5% RH, Wind Speed ±1 m/s (for speeds under 5 m/s) or ±10% (for speeds over 5 m/s), Wind Direction ±1 direction (16-point compass), Rainfall ±10%, and Barometric Pressure ±3 hPa. These specifications meet or exceed requirements for serious amateur meteorology and are suitable for professional weather monitoring and data contribution to Weather Underground's global network.

What's the difference between YC9387(W) and YC9387(T)?

The main difference is the display: YC9387(W) features a large 7" (17.8cm) colour display (168 x 143mm), while YC9387(T) has a smaller display (118 x 192.5mm). The W model has Hi/Lo/Off brightness modes, while the T model includes an Auto-dim mode with solar panel. Both models offer the same core professional weather monitoring features including 5-in-1 sensor, WiFi connectivity, Weather Underground support, and UK warranty. Choose the W model if you want the largest possible display for maximum readability.
