Sonoff-Tasmota can easily be extended by developers using provided function pointers as callback Ids. This document lists the available callback function Ids. See the wiki (https://github.com/arendst/Sonoff-Tasmota/wiki/Sensor-API) for more information.
Callback availability can be checked by searching for either XdrvCall, XsnsCall, XdspCall and XnrgCall.
The following table lists Callback Ids and their availability for a Driver, Sensor or Energy service.
