Customer Reviews
The purchase process was seamless. Setting up the WS3900 console was quite quick. The display data is well-organized and easy to read with good contrast. I would definitely order again.
WS3900_C Wi-Fi Console, 7.5'' LCD Display with IOT Intelligent Linkage Control
My wife likes it. That's my highest recommendation.
The WS3900 is a local display with hub/switch capabilities for Ecowitt products.
*Display*
The display is quite good built has clear areas for what to show and capabilities to show more when extra measurements are available. My other family members learned to read it in a couple of days and they like it. Specially I like the Lux/UVI-level display area in lower right corner that I can turn for winter time to show sunrise and -set times (I southern Finland as these vary quite a lot and have no need for UVI-level readings in the winter). Only change I would make to the display, is that the extra WH31 measurements that can now be shown instead of Out-temp I would change to be instead on the inside temperature. Last a special note of a great feature: the ability to define the display to be off by default during night-time and the time setting is programmable by the user. This is very good as the display is just outside our master bedroom.
*Hub/Switch*
Got this unit mainly to control the new Ecowitt IoT apparatuses (AC1100) and programming these are quite logical. (Worth to note that after creation a Plan or Smart mode control, one can in editing of the rule assign an own name to the rule, making it easier to know what it is) Other vice this Hub/Switch is a solid collection point for measurements, just like Ecowitt has already been doing for years. (I do have a GW1100 from earlier and the configuration of the extra devices are quite identical on these which I like and it works well)
