Code

Water Meter

This is code for the offline IDE Photon Particle Dev. If you want to use the Web IDE you need to include the HttpClient and ThingSpeak libraries.

SmartWaterMeterV3

This version allows you to update a database via an API. Included in the code are the Photon files, API server and database. You can use curl or any other web client to test. I also have http digest authentication working for the Photon as the standard HttpClient does not support it.
