Issue with HA-MQTT conf: Update Solar-Tracer Error[16] 226

[TalShaf93]

Hi,

I'm facing issues while trying to connect the solar tracer to HA (using esp8266 NodeMCU v3).
everything is setting up well: wifi - mqtt - HA etc.
but then I get this error message which by reading some of the issues here before means I have a connection problem with the solar tracer, but this connection already worked when I was trying the blynk configuration and everything worked well.

Does anyone faced such issue?

Hello, are you compiling the firmware?

• If so, please share your config.h (the one that is working fine with blynk, and the other that is not working)
• If not, make sure you're using the same serial mode (software or hardware). Files ending with "swser" are using software serial.

The config.h file is the same used with blynk and with mqtt-HA. (only used // to undefine the blynk)
Attaching file.

Blynk or HA-mqtt should not interfere with the scc <-> esp communication as thery are 2 independent "modules" .

Is there any chance that something else changed?

The startup test failed as well, this test is done before ha-mqtt or blynk are started.

I noticed that some strange chars are sent on the serial even before tring to connect to the scc (normally this will happen when communicating with the scc using an esp8266), this is strange.

Normally you should have something like this:

You can try:

1. Disable all the remote sync. (blynk and mqtt) and check if the problem persists on the serial log.
2. Use a software serial port as described here
