setup without access to solar controller

[mihai-catalin]

Hi,
My solar controller is in a different location and I am trying to setup the solar-tracer before sending it.
I choose to use ESP8266 <-> MAX485 module + SOFTWARE SERIAL with data sent over MQTT and pre-build
SolarTracerBlynk_3.0.9_esp8266_mqtt_swser.bin
Everything seems working but I don't see something on MQTT server.
Is it normal not to have something on MQTT server without a connection to scc? I see a similar topic but from it isn't clear if it was due to lack of connection or another issue.

Here is what I get on serial interface:

--- Terminal on COM5 | 115200 8-N-1
--- Available filters and text transformations: colorize, debug, default, direct, esp8266_exception_decoder, hexlify, log2file, nocontrol, printable, send_on_enter, time
--- More details at https://bit.ly/pio-monitor-filters
--- Quit: Ctrl+C | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H

MQTT-sync sends topic updates if SCC is responding, if not connected you won't get those values/topics.
Anyway some internal values (eg Internal values) should be available on yuor MQTT broker, even if SCC is not connected.

If you need more info, please provide more info about your setup and the data available on yuor MQTT broker.

Thank you for reply.
I just tried again and I get over MQTT "internal_status: 19.0000" which seems to be inline with messages over serial interface:

I suppose this is all I can do remotely. I will send it as is hoping will work from beginning.
