Re: Station hardware upgrade introduces rainfall error

I finally resolved this issue. Yesterday I concluded migrating my station's hardware and data to Weewx after experimenting with it since January this year. Meteohub has been permanently retired.

The new software has range filters that are applied to raw observation data. They are designed to ...

Re: Station hardware upgrade introduces rainfall error

I've let this go for a month because I don't want to be unreasonably demanding. I think I have a genuine problem that is not addressed in the Meteohub documentation. I can find no mention of a similar issue by searching and reading this forum. If it's covered somewhere that I've missed, maybe some ...

Station hardware upgrade introduces rainfall error

I have been running two stations concurrently: an Oregon WMR100, connected to Meteohub and a Davis VP2, running standalone. As the WMR100 was increasingly unreliable I planned to retire it and connect the VP2 to Meteohub.

On Monday I took delivery of a logger for the VP2. On Tuesday the WMR100 lost ...

Re: wifi cautionary tale

I'll report back in a week to let you know how the Edimax is behaving.
I'm afraid that "week" quickly stretched to a month. The news is good. I can report that the Edimax EW-7811Un WiFi b/g/n adapter has proven to be an excellent solution for the MeteoHub. Not a single error in 4 weeks of ...

Re: wifi cautionary tale

The new (v0.33) Media Tek firmware did produce a more stable result than 0.29. The system logs only recorded a couple of bursts of the previous messages. Sustained throughput remained well below 2 MB/s.

Following the suggestion made by PWS, I've changed the hardware:
Bus 001 Device 006: ID 7392 ...

Re: wifi cautionary tale

Thank you for that information PWS. I have no particular allegiance to a 5370-based device. The form factor caught my eye and it was available from the online shop where I purchased my RPI. I'd welcome hearing about the 802.11G/N USB devices that other MeteoHub owners are using.

I did find firmware ...

Re: wifi cautionary tale

An update on the above.

After about 20 hours of nominal operation I've seen signs of the previous symptoms. I just observed a 36-minute RT5370 failure. In that time, we logged the following:

10564 x rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry M in queue N
895 x ...

wifi cautionary tale

I encountered multiple hardware failures while bootstrapping a new Model B RPI with a generic wifi adapter based on the MediaTek RT5370 chipset. Dr Google and his associates provided plentiful advice of dubious value. Eventually, the story had a happy ending. If you're searching for a solution to a ...
