Each zone added to lovelace as a badge shows a schedule, some zone info and a switch. The switch seems to do nothing. If enabled to on, it turns itself off immediately. Would be nice to be able to turn a zone on with a timer!
Are you sure it’s not actually turning on the zone/schedule when you turn on a switch?
The fact that the switch immediately turns back off usually means there’s a problem with the webhook (how HASS gets its status from Rachio). Are you using HA cloud? If not is HA accessible from the outside? Even without the webhooks, turning on a switch should still start the zone/schedule, it just won’t show the correct state until you get the webhooks working properly.
