WiFiLogger2, VP2 and weatherlink.com rainfall readings
« on: September 12, 2023, 07:40:54 AM »
I installed a WiFiLogger 2 (firmware v2.42) in my VP2 a couple of weeks ago and have been exporting data directly to WL.com, windy, WU & WOW.

Everything has been working well apart from the rainfall readings logged by WL.com.  On WL.com the rainfall is being incremented in 0.3 mm units whereas for everything else (WFL live data, VP2 console and all non-WL.com exports) the increments are 0.2 mm.

My VP2 has a metric rain gauge with 0.2 mm buckets and the VP2 console and WFL2 are set accordingly.   On weatherlink.com the station model is set to "VP2, wireless, metric".  I suspect the 0.3 mm readings are being caused by an assumption somewhere that the rain gauge has 0.01 inch buckets but I can't figure out if this problem is the WFL2 export or weatherlink.com.

Has anyone experienced anything similar?

I raised the issue with WiFiLogger support (support@wifilogger.net).  The developer ,Wojtek,  traced the problem to a bug in v2.42 of the firmware.  Basically, an introduction message (which includes details of the rain gauge bucket size) was not being sent in this version.  This problem only affects users who have not already connected to weatherlink.com using an earlier version of firmware.

The solution was to downgrade to v2.41 and then set and save my WeatherLink credentials which triggered the introduction message to be sent.

You'll need to contact WiFiLogger support to obtain a copy of the v2.41 firmware.

Yes sounds like an imperial 0.01" gauge setting between metric of 0.254mm being round up to 1 decimal somewhere

Transmission to WL.COM is very "easy".
It is mirror of memory in Davis consoles.
You all know that there is LOOP, LOOP2, HILOWs and other command to read binary data from VP2,Vue console.

Oryginal communication to WL.COM was made for WeatherLink IP and WeatherLink PC+USB/RS232.
The data is being send with frame number. 1,2,4,5,6,7
The frames #1 is introduction frame with settings of the console. Rain gauge sizeis also in this file.

My Firmware 2.42 was written from a scratch. I just did not remember to proper server frame #1.
Frame #1 should be sent once, not repatly like LOOP data.
