On Thingspeak.com, you need to add the appropriate fields to display the sensors. The key from the site is entered in the module on the servers. Configuring the option for sending data - via TCP / UDP client or interpreter via httpget.
On a separate Thingspeak tab, you need to select the sensors, you need to send them to the service. It is required to select a metric from the list, and if the metric has several numbers, then you need to specify this in the Num field. The Num field is filled in simply with the number -number of the sensor, for example, for a DS1820 sensor. Or it is filled in with a hyphen: 3-5, for example, for D2D, where the first number indicates the number of the remote device, the second number is the number of the sensor on this device.
You cannot select sensors, only those shown in the table below are available.
field1 | DHT1/ AM2321 / DS18B20(5) / ADC int | temp |
field2 | DHT1 / AM2321 / DS18B20(4) | humidity / temp |
field3 | BMP | temp |
field4 | BMP | pressure |
field5 | DHT2 / INA219 / DS18B20(3) | temp / voltage |
field6 | DHT2 / INA219 / DS18B20(2) | humidity / current |
field7 | DS18B20(1) / LM75 | temp |
field8 | ADC int / BH1750 / Free mem | light |
