    Welcome!

    I did a test of a cheap (about $3) GSM module WIS800c and AIR208 , which I used to send data via MQTT to the Cayenne IoT cloud. During the test, I sent AT commands to the module via the YAT terminal, and the whole process can be seen below. In summary, I will write that I posted a message "temp, c=20.22" in the subscribed topic, and then took the subscription. I will try to answer any additional questions.

    I am enclosing:
    - WIS800C_AT_Command,
    - WIS800C_MQTT,
    - WIS800C_TCP,
    - screenshots.

    Welcome.

    And is this Cloud better in any way than ThingSpek ?
    Because I'm looking for such a Claud and I remember that 4-5 years tem ThingSpek works, and I would like to have something with a long period of operation.

    I've never used ThingSpeak, but if you want for the long term then a paid account would be better.

    I don't like the ThingSpeak interface, I'm looking for something like Supla.

    Supla does not send data over mqtt, and Cayenne users using the free account have a limit on the amount of data they can send. A maximum of 60 readings can be sent per minute for all sensors combined. Currently, the validity of the free account is not time-limited, but this may change in the future. At Thingspeak, the unlimited free account only lasts for 12 months --> https://www.elektroda.pl/rtvforum/topic3419769.html

    .
    Yes. The WIS800C works in Poland without changing the firmware, which is identical to the GSM module Air202T.

Topic summary

The discussion revolves around the WIS800C GSM module, which is utilized to send data via MQTT to the Cayenne IoT cloud using AT commands. The user successfully tested the module by sending a temperature reading ("temp, c=20.22") and shared various resources, including command documentation and connection diagrams. Participants compared Cayenne with other platforms like ThingSpeak and Supla, discussing the limitations of free accounts and the long-term viability of these services. The WIS800C is confirmed to operate in Poland without firmware changes, similar to the AIR208 module.
