Cumulus Support

Hi,

I've been using an Ecowitt GW1103 with Cumulus MX on a Raspberry Pi pretty successfully for about 6 months now, having moved from Oregon Scientific previously.

I'm noticing random rain spikes occasionally though. Every now and then a large amount of rain appears in the Cumulus log, but it's not present in the Ecowitt data. For example yesterday at 9:08am 195.8mm of rain got added to the Cumulus record, while the sensor recorded no rain at that time. It's happened 3 times now, I think once in each of the last 3 months (not always 195.8mm, but all have been between 100 and 200mm), but I can't discern a pattern.

Has anyone seen this before or have any ideas?

PS. Cumulus MX 3.2.6. I know it's old but I've heavily customised it and don't want the hassle of moving to the latest version if I can avoid it!

Thanks,

Martin

Have you checked rain data in the WS View app?

WS View isn't something I use. Is it likely to help find the problem? The rain spikes do not appear on ecowitt.net, where the correct data shows.

I do have an Ecowitt GW1103 including a GW100A-WiFi gateway and I do assume that you have a WiFi gateway as well?
If you do, how did you configure your gateway?

I have to admit I don't really understand how the GW1100 and CMX communicate , but in general it all seems to be working bar these spikes.

In CMX station type is set to GW1100, and the IP address points to the GW1100. On the GW1100 I had "customised", "same as Ecowitt" protocol activated, but I notice that the server IP address was wrong - it wasn't pointing to the Pi. So I have now disabled the "customised" section to see what would happen, yet CMX is still receiving the data somehow?

Thanks for your help,

Martin

With the GW1100 you tell CMX the IP address of it and it uses the api to interrogate the GW1100 to obtain the data you do not need the customised part defined in th GW1100. I don't know if that could cause an issue if enabled.

Where did you change this?

I use that section of WS View to send data to Home Assistant.

The GW1100 exposes a configuration page on your network. Simply browse to its IP address, the default password is blank.

My GW1100 do NOT exposes a configuration page on my network It does respond to ping

Is

its IP address

above = 192.168.4.1?

Are you sure you have a GW1100, the GW1000 does not respond to a browser but the GW1100 does. If it is definitely a GW1100 then it is faulty. They look identical.

I agree with broadstairs GW1100s do have a network interface and here is the proof.

And for the sake of making it clear, here is my second GW1100 on the network showing my ecowitt.net upload at 1 minute and my customised load to my CumulusMX test machine at IP address 192.168.0.158.
