Local API access to HP2650 (EDIT: HP2560!)

[SRHelicity]

[Edit: So, it turns out I mixed up model numbers. As was pointed out to me, I have the HP2560-C, which is NOT the WH2650. The former doesn't have local API access; the latter does.]

I have a new Ecowitt HP2650_C. I've been able to get CumulusMX set up to read the HTTP data coming from the 2650 using the HTTP (Ecowitt) station type with the custom server set on the console. Everything works great in that configuration. However, as I understand it, the local API access can pull in older data from the console rather than having to wait around for the console to push the latest ob (which I have set to happen every 1 min) and can pull data every ~16 s. I *think* the Ecowitt API is supposed to work with the 2650 -- see, e.g., https://osswww.ecowitt.net/uploads/2022 ... v1.6.4.pdf . In the command window / terminal, it says "Connected to station", which sounds good. However, the localhost:8998 site is showing all zeros from each sensor, and there are errors shown in the log file.

Here's a snippet of potentially relevant code from the day logfile:

Any help you can provide would be greatly appreciated! Thank you!

Looking at your log it would appear that you have picked up a GW1000 not a HP2650 using the Ecowitt protocol.

Yours states

Code: Select all

2023-07-18 21:00:00.812 Station type: 12 - GW1000

whereas my HP2551 using HTTP protocol states

Code: Select all

2023-07-15 19:06:28.082 Station type: 14 - HTTP Ecowitt

Are you allowing CumulusMX to pick up the station or have you directly pointed it at the IP address of the HP2650?

[mcrossley]

According to the "bible" I use the 2650_C only supports the WUnderground and Ecowitt HTTP methods, there is no local API.

Mark according to the User manual on the Ecowitt.com you can set up a customised server.

[SamiS]

@water01 maybe you have misunderstood the terms?

Cusomized Server means that the console is actively sending data to the selected location.

Local API on the console means that an external client (eg CumulusMX) can send queries to the console to get the requested data.

[water01]

These are the same settings as my HP2551, so the Customised server can send out HTTP via Ecowitt (i.e. Same as Ecowitt) to an IP Host as demonstrated which can be picked up by CumulusMX as demonstrated by the manual settings page.

I have a new Ecowitt HP2650_C. I've been able to get CumulusMX set up to read the HTTP data coming from the 2650 using the HTTP (Ecowitt) station type with the custom server set on the console.

I think you have mixed the station models. HP2560-C (not 2650) is a graphical display console, and it does not have local api.

However WH2650 is a small black displayless gateway (functionally comparable to GW1000/1100) and it does have the local api.

Yes, but the thread starter specifically was asking about getting the local api to work, not about the customized server.

However WH2650 is a small black displayless gateway (functionally comparable to GW1000/1200) and it does have the local api.

That's exactly what I did, I think. I have the HP2560-C console, which as you note is NOT the WH2650 gateway. Ecowitt/FO and their naming conventions...

Sorry for wasting y'all's time! CumulusMX is a great tool that was surprisingly easy to configure on my Windows 11 machine -- thanks! Mods can delete this now-useless thread, unless there's a non-trivial chance that someone else will mix up model numbers like I did!
