Yes, you can have several users who control the household at the same time. There are 3 access levels:
- Owner - There can only be one owner per. household. This user has all accesses.
- Administrator - Can do almost anything an owner can, except for deeper hub settings.
- User - Can only use the devices in the app, not change any settings. For example. turn a light on or off, but can not change an automation with the light.
There is no upper limit on the number of users per. household, but it is not recommended to have many administrators in the same place.
