To answer your advice :
I try to re-position the sensors and new batteries but nothing helps I even re-position the net but then I loose contact with my Proove on-off switch.
I have not try an external antenna but both sensors are now next to the net and even then it does not work correctly
Most common problem is the Viking sensors, maybe I should replace them by an other one but what is a good sensor ?
It can not be bad to install an external antenna so what is a good one ?
OK, if you have the sensors next to the Net and you don't still get any correct updates, I would say that you either have some kind of hardware fault or heave radio disturbances on the 433 MHz-band.
Take a look at the sensor, there should be a small transmitting icon or LED, when this icon flashes, you should see your Net flashing with a blue colour and a second later the temp.data on the PC screen is updated.
If you can't get reliable (i.e. every
60-90 seconds) temp.data updates with this set-up, a new antenna will not help.
If you have access to a radio (scanner), tunable to 433,920 MHz you can easily listen to the data transmissions from sensors and also determine if there are any disturbances on the band.
A smart sensor with several possibilities is the Wireless Multi Sensor ( http://foogadgets.tictail.com/products/hardware
) to the Multi sensor you can connect one or several sensors on a three wire data bus.
