IoTaWatt is an open hardware/open software project.
The first line of support for questions about how to install or use IoTaWatt should be the documentation available at docs.iotawatt.com.
Next would be to post your question to the community forum at community.iotawatt.com. Check the past posts first using the search box. Use the Support category when posting a new problem. The forum has the capability to easily upload and download images and files that can greatly facilitate diagnosing and fixing problems. If you don’t want to post a public conversation, there is a private message capability (“PM”).
Should all else fail, or if there is a hardware issue (very rare), send a message detailing your problem to [email protected].
