    Hi,

    Ah! Well spotted Steve, I hadn't noticed it's a Solar (charging) model.

    Isn't the Solar Pod plugged into the "Rain" socket of the Transmitter unit, and the Rain cable daisy-chained through the Pod? Either it's not been assembled correctly or perhaps there's a short-circuit (or maybe just moisture) between the Solar and Rain pins (or PCB tracks).

    The voltage from the PV cell is probably pulling up the "Rain" line at sunrise which the transmitter sees as a tip of the see-saw. I've never checked whether the tip is sensed on the positive or negative edge of the pulse (since they normally occur close together) but my guess is that it's the positive edge (or you'd get the false rain at sunset).

    We can probably help with debugging the fault if necessary, but IMHO the solar charging is largely a gimmick on those models. A pair of good quality Lithium (non-rechargeable) AA cells will probably last as long as the rest of the hardware, without solar assistance!

    Cheers, Alan.

    Good morning Steve and Alan

    Well no rain reading this morning with the solar charger unplugged. I'll keave it another day and then try connecting the rain sensor.

    I should have tried this long ago :bash:

    Thanks Gerry

    Hi Gerry,

    Note that (if it's the same as the 308x models) you can connect the Rain cable/plug directly into the socket on the Transmitter module and just ignore the Solar Pod cable. IMHO generally a better solution anyway, because you can locate the "Transmitter" unit where it can give more accurate temperature readings (i.e. in the shade), rather than put it in the sun to (unnecessarily) attempt to "charge" the batteries.

    Cheers, Alan.

    Hi Alan & Steve

    Yes the rain gauge is connected through the solar charger, and will run on it's own.

    Sunday I plugged the rain sensor back in. I poured about 8 ounces of water in it and went back inside and there was no reading. Back outside I went and there was a spider nest built under the cups, so big it wouldn't let it move. I cleaned it out put it back together. Last night it rained, after a 24 day dry spell, and I now have no rain reading at sun up and the rain last night registered the way it should.

    Now I'm off to the store for spider killer.

    Thanks to you both. :clap:

    Hi MyTemp,
    finally how did You solve the problem?
    Rain gauge is plugged in solar panel or directly to thermo/hygro transmitter?

    I had to bypass the solar charger. I now have the rain gauge going directly to the transmitter.
    Four days so far and no problems.

    Did You modify any part of the rain gauge? For example did You use any "cable extension".......
