Ventus W850

[Timo]

Hi all,

I bought a Ventus W850 (https://www.nshnordic.com/english/products/tuotteet/ventus/saaasemat/saaasema-w850-wifi-tuuli-sade-ja-10-paivan-ennuste-ventus?AreaID=51&LanguageID=LANG1, maybe the same as https://cclel.com/product/c6106a-c3146a-c3130a/). Now I'm realizing that there seems to be no support in WeeWX for that model. What are my best options to get it connected to WeeWX? Interceptor driver?

It sends reports to api.proweatherlive.net. I managed to redirect the address and with openssl got this:

$ sudo openssl s_server -key key.pem -cert cert.pem -accept 443

Hi,

I thought I'd close this issue.

I was able to get the reports from Ventus into WeeWX by creating a fake proweatherlive site. But I was not able to send any responses back to Ventus (e.g. set the clock) even if I copied exactly what proweatherlive responded. I was discouraged.

Then I tried something completely different. I have a Dragino LoRa router. Its transceiver chip can do also FSK. I replaced its LoRa receiving program with my own. Now it can receive reports from Ventus sensors and forwards them as UDP broadcasts. Then I did a little driver for WeeWX which listens for the broadcasts. Now I have a working system and a useless Ventus display.
