“After two years of watching my $300 sensor array melt in the 45°C Central Queensland sun, I learned that cheap plastic just isn't tough enough for the Aussie outback.”

Look, if you're off-grid in Australia, you don't have a weather app that works when the grid's down. You need to know what's coming. Temperature, humidity, wind, pressure. No fancy fluff. Just the essentials to keep your setup alive.
Why it matters: Your solar batteries will die if they get too hot. In summer, a 40°C day can turn your battery bank into a fire hazard. In winter, freezing temps kill battery life. You need real-time data, not just a forecast.
Practical tip: Get a sensor that logs min/max. Don't just check the current temp. You need to see the trend over 24 hours.
Australian supplier: Aurora Electronics' Temp-Log ($129) is the bare minimum. It's basic but works. For more, get the Weather Station Pro from Arduino Australia ($249) – it does temp, humidity, and wind. Both are reliable. Don't waste money on cheap $50 sensors – they die in dust storms.
Why it matters: High humidity = mould on your walls. Low humidity = static shocks that fry your electronics. In coastal areas, humidity can spike overnight. You need to know it.
Practical tip: Monitor inside AND outside. Your house might be dry, but your shed is damp. Mould eats your walls.
Australian supplier: Aurora Electronics sells a standalone humidity sensor for $89. The Weather Station Pro ($249) includes it. Skip the $30 "smart" sensor from Amazon – it fails in 3 months.
Why it matters: A sudden 60km/h gust can rip your antenna or solar panels off the roof. You need to know when it's coming, not after it happens.
Practical tip: Track wind direction too. A 40km/h wind from the north is fine. From the south? You're in trouble.
Australian supplier: Aurora Electronics' Wind Gauge ($149) is the only one that works in heavy dust. The Weather Station Pro ($249) includes it. Don't buy the $99 "wind meter" from eBay – it's useless in real wind.
Why it matters: Falling pressure = storm coming. Rising pressure = clearing. This is the best early warning you'll get. Don't ignore it.
Practical tip: Set an alert for pressure drops of 3mb or more in an hour. That's when storms hit.
Australian supplier: The Weather Station Pro ($249) includes barometric pressure. Aurora's standalone barometer is $119, but it's pointless without the other sensors. Don't waste cash on a $20 pressure sensor – it's inaccurate.
Get the Weather Station Pro ($249) from Arduino Australia. It covers all four elements. It's the only system that works reliably in Australian conditions. Spend $250 now, or spend $2500 replacing your gear after a storm. Your call. No exceptions.
Don't be the bloke who thought "the forecast said fine" until his roof was gone. Monitor properly or get off the grid.

While many off-grid projects are achievable as DIY, certain situations require licensed professionals:
Always check local regulations and obtain necessary permits before commencing work.
