It allows any device with a wired (cat5) network connection to connect to a wlan network. I.e. it is a small device that builds up a wlan connection and fowards everything received on its wlan interface to the wired interface (and vice versa). The computer behind the bridge does not have to support wlan at all, all wlan settings are done on the device itself! text/html 2018-10-28T19:37:47+00:00 Anonymous (anonymous@undisclosed.example.com) http://wiki.kainhofer.com/hardware/venta_connected?rev=1540755467&do=diff Adding WiFi-control to a Venta LW45 humidifier 1. Why adding WiFi to a traditional humidifier In our appartment, we are using a Venta LW45 air humidifier during the winter to increase air humidity to acceptable levels. These humidifiers follow a very simple principle: Several rotating disks are put into the water and a ventilator blows air through the device. The humidifier has three operating levels (1-3) and signals an error if the water reaches a low level.
