3. Enter:
   • Username (your salus-it500.com email)
   • Password
   • Optional Name

The integration will log in and create entities for each device found on your account.

Entities

Per device, the integration creates:

• climate — thermostat control
• number — frost temperature
• text (7 entities) — schedule for each day: Schedule Mon, Schedule Tue, …

Schedule format

Each daily schedule is a space-separated list of HH:MM/TEMP tokens.

Example:

06:30/21 08:30/18 17:00/21 23:00/16

Notes:

• Times must be HH:MM (24h)
• Temperature can be integer or decimal
• The device supports up to 6 entries per day (extra entries are ignored)

Service

The integration registers the service:

• salus_it500.set_schedule

Service data:

• device_id (string, required)
• day (string, required; e.g. Mon, Tue, …)
• entries (list, required; each entry like { "time": "06:30", "temp": 21 })

Polling / iot_class

This integration uses cloud polling to fetch state updates from salus-it500.com. Commands are sent to the same portal endpoints.

Troubleshooting

• If you see authentication/token errors, verify your portal credentials and that salus-it500.com is reachable from your Home Assistant instance.
• If entities don’t appear, restart Home Assistant after installing/updating.
