Advice on new installation

[Keith Jacobs]

My LeCross 23xx died after many years good service and would like to use weewx with a new station. My problem is finding a compatible weather station that can actually be bought new, apart from there expensive Davis. All others are listed as obsolete

Thanks

[Rainer Lang]

Not sure what you mean by "compatible" here - but beyond Davis there is a whole station/sensor/IoT universe

Have a look at https://www.ecowitt.com
and for a better understanding
https://www.wxforum.net/index.php?topic=40730
all these stations can be used with weewx with either the Ecowitt local Gateway driver of the interceptor driver

Thanks for that, very useful.

I guess what I meant by 'compatible' was the "Supported Hardware" list on https://weewx.com/hardware.html, almost all of which appear unobtainable.

I asked more or less the same question as Keith and I am quite happy with Rainer's recommendation (which I followed). The only thing left to make me more than happy, is to find an automatic way to backfill missing sensor data for the rare occasions, weewx isn't running for whatever reason. The 23xx did this, when you restartet weewx (if the built in memory was sufficient).

[Rainer Lang]

someone needs to add the existing backfill possibility which CumulusMX already uses to an existing driver (Ecowitt Gateway and/or interceptor) - i.e.
when an Ecowitt clone console posts to ecowitt.net (need account and console registered), using the MAC address of the console and a to-be-created APP-key and API-key one can retrieve this data on a 5-minute resolution for up to 90 days back by a http call to the ecowitt cloud API - see also https://www.wxforum.net/index.php?topic=40730

maybe an inspiration for Gary to include this functionality into his local Ecowitt Gateway driver as an option to backfill. 😎

I'm astonished that CumulusMX is the only weather software so far (known to me) which uses this possibility.
I'm sure many users of the local Ecowitt Gateway driver (GW1000 driver) would appreciate such a functionality upgrade.

I have other mechanisms in place to fill these gaps - e.g. mirror installations etc. including using the CumulusMX database files running CMX in parallel and then do the manual backfill with wee_import;
that's a  maximum semi-automated solution; however, a fully automated approach for weewx jumping in at restart when a gap is detected would be definitely much better

You're perhaps reading a little too literally there.  Model numbers come and go and there is so much rebranding of the same models under the hood by different sellers that it's a bit impossible to keep a current list.  The v5 docs have a differently formatted list at https://www.weewx.com/docs/5.0/hardware/drivers/ that might help possibly.

If you look at the weewx map at https://weewx.com/stations.html and click on the hardware button on the right, you'll see the distribution of 'registered' systems.  Perhaps that will help.  Of note are ecowitt (GW1000 driver) and weatherflow (weatherflowUDP driver) as two examples of good drivers for gear that is available very easily.

Hi:

I currently have weewx installed on a couple of Raspberry Pis (one dealing with indoor sensors and another with outdoor sensors) using 1-Wire devices, DSB1820 sensors, 1-Wire rain gauge, 1-Wire Wind direction and speed, etc.

I am wondering if v5 will support 1-Wire devices and if so what driver to use.

Thanks

Try looking at the hardware list https://weewx.com/hardware.html please.  A quick google search for 'weewx 1wire' will return lots of info.  A quick google search of 'this' group for '1wire' will return lots more info.

[Michael Form]

Thanks for the quick reply. My question is will v5 of weewx support a 1-wire driver? Should I just use the same driver that I already use for v4 or will it have to be modified?

Thanks.

Mike

which driver are you using for 1-wire?

in most cases, a driver that works in weewx v4 will work fine in weewx v5, IF you are using python3.  if you are using weewx v4 with python2, then you must ensure that the driver has been converted to work with python3 before it will work in weewx v5.

Even better would be the possibility to query their consoles directly. No cloud, no internet, just ask the device, using LAN connection, to provide the data. This should be possible in theory, even for the GW2000 without the SD-Slot, at least for a 5-min-interval for a couple of days, if they (ecowitt) wanted to implement it.
