Cannot connect to MQTT with lilygo-rtl_433

I cannot connect to my mqtt with version 1,5 (1.4 connected but I did not have any luck connecting to my weather station)
My device is a LilyGO 433Mhz model: T3 V1.6.1
It does say “wifi Connected” on the led screen then the OPenMQTTgateway comes up in black.

Hello Tom,

Sorry to hear that, could you do an erase from the web portal below:
https://espressif.github.io/esptool-js/

And reflash the 1.5.0

Thanks for that.
I did an erase as requested, but still have same result with no MQTT connection.
Here are the logs…

Hello,

After the erase and the reupload, did you had to reenter the credentials in the wifi portal?

I did the erase and started from scratch. It did the usual and asked for wifi etc. Then rebooted.
With my MQTT broker I still did not get a response. (which I did with 1.4).
I am NOT using Home Assistant (will soon) but a Delphi program which I wrote which has an MQTT broker and client. This works well with all my MQTT clients.
So what I will do next is setup Home Assistant and a MQTT broker installed.
Will keep you posted.

With home assistant and MQTT broker it now works.
All I need to get up and going is my Ambient Weather WS-2902 station.

On your Delphi was the prefix also home/ or something different?
I had problems once on HA and homeassistant/ worked for me but I may have had a config error somewhere that prevented the home/

Hi @Tom_Duncan, I have exactly the same board :smiley: and exactly the same problem :frowning:
it was working with 1.4, but it doesn’t work with 1.5

Did you manage to rollback to 1.4?

10

No, sorry about that. Just hoping that someone can get it working for us.

Hey, I have exactly the same issue when connecting to mosquitto broker :frowning:.
Other ESP32s running ESPHome and ESPresense can connect just fine…

12

Do you use a username and password with your broker ?

13

Never mind, I’ve just updated to the newly released version 1.6 of OpenMQTTGateway and the issue is gone!

I have gone to 1.6 as well. All is good.
However I have nothing from my FineOffset weather station.
