Dear Christophe,
Netro IFTTT returns local time for convenience, where the time zone is determined by your device address. The API returns
1. date: local date
2. start_time: local start time, please use only the time part and ignore the date and time zone part if any.
3. end_time: local end time, similar with above.
We have checked the API, it seems OK. For example, you have a schedule on 2020/09/10, from 06:00am to 06:28am, the API returns:
{"device":"Pontaillac ","zone":1,"date":"2020-09-10","start_time":"2020-09-10T06:00:00.000Z","end_time":"2020-09-10T06:28:00.000Z","source":"SMART","status":"EXECUTED","meta":{"id":94827648,"timestamp":1599710400}}
Please note that "2020-09-10T06:28:00.000Z" is not UTC time, only use the "06:28:00" part, although system may add date and timezone part automatically.
Please let us know if you have more concerns.
