The maximum number of fields per ThingSpeak channel is currently 8, so you won't be able to save 11 fields per channel with a standard license. However, ThingSpeak does offer a custom enterprise solution that allows for more than 8 fields per channel. You can contact ThingSpeak's sales team to discuss the pricing and features of the enterprise solution.
If you don't want to upgrade to the enterprise solution, there are a few possible workarounds that you can try:
- Combine multiple fields into a single field: Depending on the nature of your data, you may be able to combine some of the fields you want to save into a single field. For example, if you have separate fields for temperature, humidity, and pressure, you could combine them into a single field delimited by commas or semicolons.
- Use a different channel for each set of fields: If your data is logically separable into multiple sets, you could create a separate ThingSpeak channel for each set of fields. For example, you could have one channel for temperature and humidity data, and another channel for pressure data.
- Use a different IoT platform: If neither of the above options work for you, you may want to consider using a different IoT platform that supports more than 8 fields per channel. There are many other IoT platforms available, such as AWS IoT, Microsoft Azure IoT, and Google Cloud IoT, among others.
It's worth noting that the standard ThingSpeak license is designed for hobbyists and small-scale projects, so if you're working on a larger project with more complex requirements, you may want to consider upgrading to the enterprise solution or using a different IoT platform altogether.
