Yeah, green light, my bad. So, here is my experience, please tell me if this is correct behavior.
- Wake up in morning after a long period of idle time and hit the buttons - Green light flashes until bowl ready
- Touch buttons 30 min after morning session - Green light solid
- Unpress and repress buttons - Green light flashes until bowl ready
According to what you are saying, there is a standby mode. This seems to expire at some point as well, because if I wait long enough in between sessions (for example, overnight) the next time I come back to it, it will flash again.
