Hi,
I am quite new in this area and would want to connect ESP8266 running Tasmota 8.1.0 to Cayenne.
Is that possible and this works?

When I setup MQTT in Tasmota and restart ESP8266 then in console I got:

20:40:55 MQT: Attempting connection…
20:40:55 MQT: Connected
20:40:55 MQT: tele/tasmota/LWT = Online (retained)
20:40:55 MQT: cmnd/tasmota/POWER =

But then after about 30sec then:

20:40:56 MQT: Attempting connection…
20:40:56 MQT: Connect failed to mqtt.mydevices.com:1883, rc 5. Retry in 10 sec
20:41:07 MQT: Attempting connection…
20:41:08 MQT: Connect failed to mqtt.mydevices.com:1883, rc 5. Retry in 10 sec
20:41:18 MQT: Attempting connection…

??
Can anyone explain me that?

Tasmota is and small OS running on ESP8266 which also offer MQTT communication.

Brief information here:

It doesn’t offer programming directly in code but thru settings and scripts, rules to avoid directly programming in C or other language which would need additional compiling.

So when I get required data for connection
Chayenne

I add this to Tasmota MQTT settings

TasmotaMQTT
TasmotaMQTT404×750 46.1 KB

And after restart then I got that log from previous message.
As frim that log I understand This client connect to Cayenne for few minutes but is then later disconnected?
