Factory behavior worth matching

• The unit sleeps almost all the time and wakes on a timer, the front button and bottle changes. See Power and Sleep.
• A dose is the valve held open for a set time. Doses can start from the button, an on-device schedule, or a remote command.
• Dispensing is blocked when the battery is low (20% by default) or when the bottle's dose limit is used up.
• During WiFi setup the unit serves a small local web page ("iFLO Connection"). See Network Protocol.

Valve

A motor- or solenoid-driven valve on two driver pins. See Hardware GPIO Map and Board and Connectors.
