 This integration queries the ECU with a set interval for new data. This was done without a public API, and by listening to and interpreting the protocol the APSystems ECU phone app (ECUapp) uses when setting up the PV array. This couldn't have been done without the hardwork of @checking12 and @HAEdwin on the home assistant forum, and all the other people from this forum (https://gathering.tweakers.net/forum/list_messages/2032302/1). Thanks goes out to @12christiaan and @ViperRNMC for providing an automated solution to restart the ECU-C and ECU-R (SunSpec logo/ECU-ID starting with 2162xxxxxxxx) models.
