fine offset wh1081 or Maplins USB weather Forecaster prob

Post by hermitage777 »

In have a Maplins USB weather Forecaster or fine offset wh1081.

I have had the system for about 2 years and it was working great...

I had an accident (out of control bonfire) the remote unit melted!

I have bought a new system and it works just fine. However I had hoped the old base unit would receive data from the new remote instruments but it doesn't .
Both units say 433.9 mgheartz. Is there some thing I should be doing or won't 2 units work with this system?

Many thanks

Hi Chris,
Sorry to hear about the fire.

I have got two units running of my sensors. I think all you need to do is unplug the console from the usb if it is plugged into a pc, and take out the battery's out of the unit that you can not get to work and but them back in and it should now start to work.

Please let me know how you get on?
Mike

Hi Michael.
Thanks for your prompt reply.
I haven't connected the new unit to pc yet and the old one hasn't been connected for a while.
I have done as you suggested and removed batteries from the base station and when reinstalled the unit displays all the internal icons but not the remote ones ie os temp, ws, direction.
Any more ideas please?

Thanks Chris

Hi Chris,
I am sorry that did not make it work. It is very strange that they are on the same freq and it still does not work.

Maybe try leaving the battery's out longer in the old display unit, to see if that would work.

If that still does not work I can not think of anything else to try.

try taking the batteies out of both remote units then from the sender. power up both the remotes and then power up the sender unit. from what i understand about the wh1081 when the sender first connects to the remote unit it sends a code so it will only pick up that unit. i have 2 sender units working to to remote one is only used to monitor the green house the other for the unormal weather we are having here on the west coast of scotland. hope this work for you

Hi,
been doing some research on the usb issue and caught a few people talking about the differences that caused the old/new units not to interchange.

I suspect this is the reason why one transmitter won't talk to a different age base unit:
Fine Offset WH1080 weather stations, and various OEM verison of it changed protocol from OOK to FSK somewhere in 2012.
This comes from a rasberry pi project working on using the outdoor sensors from WH1081 (specifically a Maplin N96GY) with rf boards connected to the rasberry pi.
Written in July 2012 the authors refers to 433Mhz specifically.

for the byte oriented technical readers the two web pages that i refer to are:-

Hi,

IMHO that information is misleading. Various threads have discussed the matter, but in particular see my recent post in this thread.

Cheers, Alan.
