Switching from ethernet gateway to MQTT
Inso last edited by Inso
I want to switch from an ethernet- to an MQTT-gateway, to be able to add some ESP8266 and ESP32 "natively", i.e. without extra nRF24-modules.
From all I´ve read, my "old" gateway (ethernet) uses the nRF24-module of my Raspi to communicate with the nodes. MySensors handels the messaging stuff, talks to Domoticz using the easy-to-use LAN interface.
Switching from ethernet to MQTT means I have the option to send also data per MQTT to and from the MS-gateway, besides the "usual nRF24-way". Only difference is to setup a MQTT gateway instead of the ethernet-gateway within domotics and to install a Mosquitto Broker (Server). Now the communication Domoticz <-> MySensors uses
MQTTthe usual ethernet gateway, nodes can connect the "usual way" using nRF24 or communicate using MQTT. MySensors uses the Mosquitto server for some implementation(?).Communication is then node <-> Mosquitto Broker <-> MySensors <-> Domoticz (?)
Sadly, the Domoticz tutorial is very unclear about that , it just said install Mosquitto, you need it. Also the Build-section here did not help much, and reading here on the forum did confuse more then it helped.
However, I managed it to let Domoticz and MySensors connect fine.

Problems starting with having no Version on hardware-tab (MySensors Gateway with MQTT interface
Version: ?), and the type of my "old" nodes is not recognized. I see the Node IDs I gave em, children type is unknown, values (f.e. #1.V_TEMP (24.3)) are received, but do not show up at the devices tab.
Do I have to rewrite all the Nodes to now use MQTT? As the nRF-nodes have no ethernet-interface, I only could add MY_MQTT_PUBLISH_TOPIC_PREFIX and MY_MQTT_SUBSCRIBE_TOPIC_PREFIX.
Sorry if I am asking noobish questions here, I´m only searching for a good way to let Arduinos and ESPs work side by side fine while using the hardware they provide.
From all I´ve read, a MQTT gateway is the best way (better then connect every ESP as a separate gateway). Or maybe I have missed something?

Update: rebuild from the bones. Raspi-OS, Domoticz, Mosquitto, MySensors.
I don´t get a version of my gateway nether.
Sensors run but have to be renamed complete within Domotics (database backup did not help), and all data is lost.
