Hello!
I am configuring the RUT955 (FW version: RUT9XX_R_00.06.08.3) to work as a MQTT gateway between a Solar Inverter (Modbus data) and a MQTT broker.
I have run into several issues trying to figure this out. I tried setting up different topologies according to this manual: https://community.teltonika-networks.com/?qa=blob&qa_blobid=4208100263841122966
In the 1st example I set up 2 RUT955 routers as slave, master/gateway and broker. I successfully set up Slave/Master. When configuring the Flespi.io broker to the gateway I am unable to connect them together. Flespi settings say that the password is supposed to be left blank, but RUT requires either UN+PW or none at all. As an alternative, Flespi instructs to connect instead with Token ID as username and Token itself as PW, but this does not seem to work aswell. (Works only with ASC token). Tried with and without "FlespiToken_" infront of the Token code, does not connect. Tried with ports 443, 1883, 80 and 8883.
When inside MQTT board I subscribe to topics "respond" and publish to "request". When I publish a request with a correct message format, no response comes from Subscribe tab...
I assume the issue might be in connecting Gateway to Flespi, because the login procedure is messy.
After countless tries I moved on to the 2nd topology.
In the 2nd example I connect 3 RUT routers together as instructed in the manual. First is configured as Master/Gateway, 2nd is slave and 3rd is the Broker. I connect these all with different IP addresses (master IP ending .1 - slave .2 and broker .3) and control them through master router using Port Forwarding. Connecting all with LAN.
Configured Slave/Master as before. Test worked.
Configured MQTT broker to listen port 1883. I subscribe to the broker topic "respond" and publish to "request". I do not get a response.
Format I am using: mosquito_pub -h [Host] -h [Host_address] -p [Port] -m [‘Message’] -t [Topic] and "0 65432 0 192.168.1.2 502 5 1 3 2 2" as payload message.
(Also tried with Bridge/Publisher enabled. When I do, I see in Terminal window that 192.168.1.3 - RUT MQTT broker is connecting as client. As I understand bridge is necessary to pass on data from Gateway to Mosquitto Broker?) I enter my PC IP there.)
It seems to me that the MQTT gateway is not working since it is not passing the request along to the Master>Slave...
Can someone give suggestions how I can get this running?
Overall, my end goal is to use MQTT gateway to exchange/push the parameters of a solar inverter (status/voltage/power..) to the Broker and to be able to read this data as different Topics from the brokers side. Is this even possible? Considering that the gateway needs to be receiving individual request messages from the broker... I would like to have real-time data pushed from the inverter through MQTT.
Any help is greatly appreciated,
If my configuration is unsuitable then feel free to requests alternatives.
Kind Regards
Boris
