Raw APIs as well as a RainMaker service have been provided to manage timezones.
Timezone information is stored in NVS so that it stays even across reboots.
A config option CONFIG_ESP_RMAKER_DEF_TIMEZONE has also been added to set the
default timezone.
Some string parameters may want to have a set of valid values which
it wants the client (phone apps primarily) to show in a dropdown.
A new API esp_rmaker_param_add_valid_str_list() has been added for that.
Validating the JSON arrays and objects would be the application's responsibility.
The RainMaker core will just treat them as strings (without the quotes, ofcourse).
- APIs and data structures changed to a more object oriented approach.
- Some internal files split into multiple files to separate out functionality
of node, device and parameter.
- A new doc file CHANGES.md added to help understand the changes.
- Modified all the examples as per these changes in the RainMaker APIs.
