In this project we implement a firmware by WIZ550web SW modification. We can manage the status of equipment even if it is so far.
This article is about using the WIZ550web with an adjusted firmware to directly send and receive multicasts from a KNX Gateway to communicate with the professional homeautomation KNX bus. In multiple steps it is shown how to add PIR sensor to a WIZ550web. The WIZ550web is then sending multicast directly to the ethernet. The gateway is then transferring this data to the KNX bus. Voila - the stairway light goes on.
webinar about the W5500 Hardwired TCP/IP core tech. + how to use it for Serial-to-Ethernet, here WIZ550S2E, and for small webservers like WIZ550web.
