I have a development that requires 12 fields, but ThingSpeak only offers 8. Without further subscription, can I combine 2 Channels ? Can I combine at least two Channels ? The free license is limited to four channels, so you can have one device speak consecutively to two channels without issue.In this scenario, when you get to three devices, you'll need to upgrade. Can you tell us anything more about your project? (always curious to hear about ThingSpeak projects) Excellent. I'm working on Primoroni Environ Plus which measures Temperature, Pressure, etc and when combined with a Particulate Matter sensor also measures other particulates. So I have about 14 components to measure. The solution will measure these components, and compare it with recommended thresholds to display various information/data on ThingSpeak. channels.
