Add support for multiple powered winders on one network

[mwood77]

There's a possibility more than one powered unit will be on the network. Therefore, each winder should search the network to discover if there are other active winders already on the network & available at http://winderoo.local.

If there are, it should try to find an 'available 'domain' on the network.

The code could be something like:

 // pseudo code..
 int domainNumber;     

 // winder exists
 if (PING winderoo.local (status code) == 200) {
    // find incremented mDNS address to use

    for (int i = 0; i < 10; i++) {
        if (PING winderoo[i].local (status code) != 200) {
             domainNumber = i;
             break;
        }
    }
    MDNS.begin("winderoo"+domainNumber);
 }

Also requesting this feature... Have 3 powered winders and all named winderoo.local. Would prefer option to configure DNS name during wifi setup. FWIW I tried a search/replace in the source code from winderoo.local -> winderoo2.local and built/deployed it but it didnt appear to do anything when I pushed it to the ESP32

You could try changing the name here on your N+1 winderoos, until I implement this.

This line sets the domain name, winderoo.local:

winderoo/src/platformio/osww-server/src/main.cpp

Line 562 in 644702f

if (!MDNS.begin("winderoo"))

Thanks, that worked!

I've just finished adding in support for OLED screens (bit of a distraction), so I hope i'll be able to focus on this networking task soon.
