Hi, Yes, Ecowitt reports the wind direction in Degrees but I don't (yet) know what data format is transmitted over the wireless protocol (at 868 MHz) and haven't seen the resolution , let alone accuracy , specified anywhere. The old Fine Offset (WH108x, etc.) Vanes actually had 8 magnetic sensors (r...

Hi, The lines of the actuating magnet field need to run along the length of the Reeds, so it doesn't matter if the reeds face each other "sideways" or "one above the other". This magnetic field turns the two reeds into "bar" magnets and since they are offset end to end,...

Hi, Personally, I try to find a modern Synthesiser type Transmitter (with a crystal in a rectangular/oval package), in preference to the old SAW (Surface Acoustic Wave Filter) in a circular "TO5 style" Metal Can. But they don't seem as easy to find in UK now, except with expensive and/or s...

Hi, Beware that I once purchased a "spare" T/H/Wind transmitter Module which did have 6-pins in its Rain socket, but did NOT transmit the Pod data, so presumably not all are WH308x compatible. I strongly suspect that at some point FO "standardised" on the 6p6c socket in the T/H t...

Hi, If you decide to get the Pod, then first you can plug it directly into the Rain socket and see if it transmits. Note the rain switch is connected across the two middle pins so it can plug into either the Pod or the original T/H Rain socket. Also, all the encoding for the separate Solar Packet is...

Hi, The Fine Offset company now appears to have "morphed" into "Ecowitt" and I don't know if they are still manufacturing their original products; some "spares" are still available, but usually at a greatly inflated price. However, the Solar Pod is available at a very f...

Hi, HERE is the Ebay link that I found; it does appear to be a Chinese seller, who seems to have been selling around one each day for the past few weeks. He has a very good "feedback" rating, however I couldn't find any feedback (or reviews) for that particular item (but I must admit that ...

Hi, AliExpress will not let me order it to UK: This product can't be shipped to your address. Select another product or address. .. I just bought one a week ago (delivery between 4-14 may :( Yes, I find AliExpress particularly frustrating; sometimes most of the items that they promote in their email...

Hi, Welcome to the forum. The station was manufactured by "Fine Offset" (Chinese of course) and there are plenty of details in This section of the forum . It's possible to set up a/the "Relative Pressure" via the touchscreen (if it works) or Cumulus can be arranged to "ignor...

Hi, Welcome to the forum. I am not aware of a "crystal" close to the Lux sensor (under the white dome). Have you seen the photos near to the foot of Page 4 of This Long Thread in the "Fine Offset" (who manufactured this range of stations) section of the forum? Note that the "...

Hi, There have been various versions of the transmitter (at 433, 868 and 915 MHz) but IIRC the typical current drain whilst transmitting was about 20 mA. However, the transmission should last for less than 100 ms in each 48 second cycle. For most of the remaining time the microcontroller should be &...

Hi, If a set of new Duracells Plus Alkalines last more than a month I am happy. It appears that your Transmitter is fundamentally "faulty", but I can't add any more on testing than in my posts each side of yours above (on 11th January 2022). AFAIK, Lithium (Primary) Cells have a similar di...

AllyCat

Hi, If it is indeed 3600 samples, it was originally probably meant to be just the last hour. No I don't think so. AFAIK the 3600 is correct and dates back to (the early days of ?) Steve's original Cumulus 1. That only "read" the data once each minute and typically logged it even less frequ...

AllyCat

Hi, The Icon should indicate that the Transmitter battery is below about 2.5v (i.e. 1.25v per cell), however it may not go out for some hours (or a day) after the cells are replaced as above (or the Console is re-booted). IIRC there is no battery icon for the Console itself, the only indication of l...

AllyCat

Hi, The (post 2012 ish) transmitter is basically a very simple OOK (AM) type and could be replaced, but the problem is probably the microcontroller which is "Chip On Board" (under a blob of epoxy) or the (largely unidentified) Humidity/temperature sensor which (if it has failed) I believe ...
