I have the MQTT gateway and vibration V3 unit. I’ve followed all the Ubidots instructions, but it does not appear automatically as it should. The Gateway does not appear either, but I don’t know if that would appear without a successful sensor connection. I did at one point see the sensor appear in the gateway devices. The Gateway has a green light.
Attached is the configuration of the Gateway. I’ve attempted no config changes on the sensor and operating purely from a browser (Mac user). The Endpoint fields had the default but some documentation suggested leaving these blank.
So far the only suggestion from the Ubidots community is the sensor may have a data format that is not recognized by the broker.
