Radio controlled weather station help

[Skyline]

I won this on ebay. Brand new for a tenner.
I had one before but it had no where near what's on this one. That died last week after 10 years of service.

Everything on the main display seems to be working well and has picked up the outside sensor.
There's one thing I have no idea what it's for. There's nothing in the manual about it. It the little wire/aerial that can be fitted in the outside sensor. Anyone know what it is for? Do I need to use it?










(The sensor isn't in direct sunlight, it hits on that wall of the house for about 30 minutes a day when the sun is out)

The additional wire thingy looks like a remote sensor, so the actual transmitter can be sited in a dry spot with the sensor out in the rain. Easy to check - just hold the (?) remote sensor in your hand and see if the reading rises while you're doing so.

Temp sensors are usually mounted in the shade. (Google Steveson screen).

It did go up when I held it to put that wire in.

As said in post, The sensor isn't in direct sunlight, it hits on that wall of the house for about 30 minutes a day when the sun is out.
It says in the book to have it north facing. On that wall the sun only hits it for a very short about of time as houses block it off. If you think 30 mins or so will make a difference to it I will move it somewhere else?
I put it there because rain doesn't hit that wall.

Not worth being too fussy unless you are set on getting strictly accurate results at all times of day.

That little dongle might be the temperature sensor (may also measure humidity levels too) and should be placed in a shaded area for the most consistent outdoors readings (air temperatures are measured in the shade as standard, that's why the Met Office have instruments stored in them bee-hive looking Stevenson screens).

The transmitter itself should be kept indoors as that might get ruined by rain, ice and wind. That would do the job of measuring air temp and humidity indoors.

It seems to be giving me correct results even if the sun hits it for 30 minutes. They rest of the days it's in the shade.
