Like some other reviewers, I had Davis Instruments stations previously, but they'd become too expensive. I bought my first WS-0310 in Jan 2021 and really liked the colorful, easy-to-read display. I didn't have any trouble setting up the Wi-Fi (I used my laptop's browser, not the Sainlogic App), and other than the batteries being a little loose when the cover was closed, I was happy with the system. (I wadded up some plastic before closing the battery cover to firmly hold the batteries in place now).

In Jan 2023 I bought another system, mainly to get a 2nd console for the bedroom, and I used the new outdoor sensor unit. Even though the display unit is now at V2, both the new and the older one receive and display the data perfectly. I only upload to Weathercloud.net from the newer console.

Last week I noticed that the Sunlight reading was way off. On a late Spring day with no clouds in the sky, it was reading between 25 and 80 W/m² when the actual value should have been around 1200. The UV reading was still 7 or 8, so it wasn't affected.

I eventually saw that the Sunlight reading would jump back and forth between 1200 and some ridiculously low value every time the display updated (every 16 seconds). When I contacted tech support and showed them a video of the extreme fluctuation, they sent me a new sensor unit right away.

I'm happy to say that everything's working again, and they reached out to me today to make sure the replacement unit solved the problem. I thought that was worth writing about here :)
