Tests on our own home Mqtt servers
As described in the Gui-O manual.
"We offer our own broker server for testing purposes".
In my case and possibly many others, would also like to do testing on our home server.
In this part, the ask is if you can help us with it, when you have some time available, to make a small step by step tutorial, which broker and how to install on Windows, with all the necessary configurations for a good functionality with Gui-O.
I think that everyone in the Gui-O community would be grateful for this contribution, and for the excellent support that has been given to us.
our MQTT broker is based on Mosquitto:
It listens on three ports:
1883 - unencrypted, requires user name & password
8883 - encrypted, requires client certificate + user name & password
8884 - encrypted, requires CA (our) self-signed certificate
The GUI-O app currently only works on 8883 (for development purposes, I can enable operation on port 1883 - this is not for production, since the connection is not secure). Ports 1883 and 8884 are for uP devices (e.g., ESP32 - https://www.gui-o.com/examples).
There are a lot of tutorials online (for Windows and Linux) on how to setup your own broker. I would only be duplicating solid tutorials that are already available.
You can also use free third-party brokers (for example https://www.hivemq.com/downloads/), where you can freely connect limited number of devices.
