Arduino cannot connect to Cayenne Cloud

Is it possible to change the MQTT server hostname from the Arduino code, so I can use the IP address ?

i guess you solved this by changing it in CayenneDefines.h.

@anpa

When adding a widget I can only select Virtual from the Connectivity field, why aren’t there the Analog and Digital options ?

virtual channel are MQTT channels used to send data between device and cayenne server. There are not related to analog or digital connective. but then you can use the data received from this channel to do whatever you want.

@anpa

It seems the sensors are sending data every 15 seconds. Where is this configured?, can I change this value ? Or add some sort of timer or trigger for sending the data from the device to the cloud ?

have a look at this topic Sending MQTT messages within rate limits

@anpa

When using a Line Chart, is it possible to define a threshold for the data, so that it generates an ON/OFF chart, OS when the data is above and OFF when the data is below ?

i did not understand this
