WH1080 sender / receiver appears to have died, suggestions?

[James Muirhead]

My WH1080 sender / receiver appears to have died. 

The battery low indicator had been on for some time and died about 0130 this morning.

I changed out the batteries in the sender today and it does not want to communicate with the receiver now. LED in the sender comes on and receiver appears normal.

I've reset receiver and sender in both orders and left for an hour, etc, etc. WeeWX WebUI shows no signal (but I don't know how this is generated).

The communication icon on receiver comes up sporadically for a minute at start and for quarter of a second once in a while.

I'm gonna take apart the sender tomorrow and give everything a good clean, see if it helps.

Has anyone got a suggestion, other than "buy a new weather station"?

Thanks.

PS - WeeWX is working perfectly. But I have WeeWX installed on an Orange Pi PC (1.3GHz Quad, 1GB RAM). Shout if you want anymore information.

read the manual - there is a button to press (i forget which) to regain communications.  Just looked - press and hold the down key for 4 seconds until the console beeps.

Register transmitter If no outdoor weather data is displayed or the signal to the sensors is lost during setting up, mounting, changing of batteries to the sensor or plugging or unplugging cables, simply press and hold the DOWN/- key for 4 seconds and a short beep will sound to synchronize the base station to sensors. Without being synchronized, weather data will not be received. NOTE: Wait two minutes before re-insert the batteries of transmitter for proper reset. Note: The best condition for reception is at night, between midnight and 6:00am – when there is less atmospheric interference.

I lost my manual aeons ago, have downloaded. It's on it's 10th (ish) set of batteries now!

I tried to press down arrow for 4 seconds, but has no effect (backlight goes off, about it).

I tried to remove batteries for about 30 minutes yesterday (so I could give whole thing a good clean). And they died at some point in middle of night anyhow.

Manual also says it will attempt to reconnect every hour, and I've so far left it for almost a whole day and still no connection.

Any other ideas?

Many thanks.

from memory I THINK that when you press the down button the icon starts to flash and it beeps and then it is hunting for the transmitter.  If it does not beep it is not searching.  Did you change the batteries in the transmitter AND the console?  Did you wait 2 minutes before reinserting new batteries in the transmitter?  You could also try with the console outside closer to the transmitter - and the manual suggests doing this resync at night.  Otherwise maybe it has died a death ... RIP...

I didn't change batteries in receiver as such. I've previously converted it to Lipo and charges via USB connection to Pi. But I did disconnect and reconnect said battery. And yes, on at least one occurance I did wait 2 minutes. Done about every combination.

Doesn't beep when press down button for for seconds.

Thanks.

I had issue last week with regain connection when I changed batteries in the sender. I had to move the sender and receiver closer to get the connection up again. And this has been the procedure every battery change before. Worth a try.

I tried to resync it at 1am, no joy. However I did notice that the sender LED doesn't go off. It just stays on and flickers.

I took apart the sender (FYI it's glued shut) and gave it a good clean (with IPA and a toothbrush).

Oh, and I dug out my SDR gear and checked if it was actually broadcasting anything on 838MHz. But no dice, that area of band is strangely dead right now!

So I have a few theories... 

1) Some IC on the sender is stuck in a boot loop for whatever reason.

2) There's an intermittent connection I haven't found.

3) Do we know what sender does if one of the other sensors isn't connected? Does it just boot loop? Because if there's a dead sensor, it may just be that.

I'll have to see what I can come up with.

Thanks for the help thus far...

PS - So looks like I shall be buying another weather station. Anyone got any recommendations on one generally available in UK, that won't break bank and works with WeeWX? Preferably without needing an SSD receiver (personal preference).

PPS - In fairness, it did last over 10 years!
