RS485 Pyranometer and Weewx

[Jon Fear]

Hi Folks

Just been gifted a Vaisala WTX536 which will now become my goto device for my weather station. I have a WS90 Wittboy with a separate rain gauge and Temperature sensor. I also have a Davis Vue which seems to be missing the rain side of things....

So to the min part of the post, a Pyranometer.

Has anyone yet tried the Pyranometers that are now coming out of China such as this one:

Which is good for solar radiation or this  one:

Which appears to cover UV.

Obviously there is  the calibration element of this but has anyone:

1. Tried either?

2. if so interfaced it with Weewx?

3. Got Weewx to take data from multiple sources.

I am thinking of selling the WS90 but keeping the rain gauge and the soil sensors, keeping the Davis, keeping the Vaisala and adding at least the solar radiation sensor.

Any sensible thoughts, comments and suggestions would be welcome. Unfortunately I am another of those people that do not do code. I am a hardware man...If you need it made, easy, simple PTH electronics no problem! Code, I'll get my hat!

Thank you folks

Jon

I have got another device that uses an RS485 interface. I use an RS485 to LAN converter from W&T. It depends on the protocol they use, but may be the MQTTSubscribe driver/service can read the data into WeeWX.

Jon,

Did you make any progress with either of those units? I'd be glad to hear any details.
