Hi. I’'m using Openhabian on RPI3 Server for quite a while. My network setup is as follows:
behind home internet Firewall which provides home ethernet/WLAN I have another router, which is connected with WAN port to my home ethernet network. This router serves separate WLAN with is used solely for my OH system - Shellies, Sonoff and Home Control Touchpanels (all via MQTT broker, located on OH). Rpi/Openhabian is connected to this router via wired Ethernet port.
Now I have an Idea - what if I plug my RPI to my home ethernet directly and enable Wi-Fi access point on it, so that Shellies and Sonoffs would connect to RPI instead of router and RPI would serve as a router for them?
Should work, right? The only question - does Openhabian have a setup for it, or does anyone already tried the steps to activate Wi-FI in AP mode on RPI3 parallel to Opehabian? Did it work?
Well, I don’t see any reason why this feature can’t become a part of Openhabian architecture some day.
Actually I’m even a bit surprised that it’s not a part of platform already: nowadays more and more smart home devices communicate over Wi-Fi and people might want to put them all into dedicated WLAN serving only for smart home functionality in order not to interfere with other devices.
RPi offers Wi-Fi AP option, so it’s could serve both as Openhabian server and AP for Wi-Fi smart home devices. If people want so. I’m not saying this should be a default feature, but an option, like it is with Node-RED for example.
