Timer command not working for roborock.vacuum.a15

[moeffju]

Describe the bug I have a Roborock S7, model roborock.vacuum.a15, which according to the docs should be supporting getting the timers/schedules, but the timer command only returns an empty list.

Version information (please complete the following information):

• OS: macOS
• python-miio: miiocli, version 0.6.0.dev0

Device information: If the issue is specific to a device [Use miiocli device --ip <ip address> --token <token> info]:

• Model: roborock.vacuum.a15
• Hardware version:Linux
• Firmware version: 4.3.5_1612

To Reproduce Steps to reproduce the behavior:

• mirobo --ip $VACUUM_IP --token $VACUUM_TOKEN timer

I also tried with genericmiot but couldn't find a timer action or sensor, and calling get_timer didn't work.

Expected behavior I expect to see the schedules I defined in the Mi Home app.

Console output

# mirobo --ip $VACUUM_IP --token $VACUUM_TOKEN timer
Timezone: Europe/Berlin
