ESP Easy only sends information about sensors to connected controllers. If you don't have any sensors (or "devices") connected to the ESP Easy board (yet?), you can force it to send events to Homey every minute by adding a dummy "System info" device.

• Make sure you have added Homey as a controller to the ESP unit first
• Go to the "Devices" tab in the webinterface of your unit
• Click the "Add" button in the first empty spot
• Select "Generic - System info" from the device dropdown list
• Give it a name like "System" and check "Enabled"
• Check the box for "Send to controller" next to the Homey controller under "Data Acquisition"
• Set the IDX value of the device to some unique value other than 0
  • Tip: I usually just put the device number there. Read more...
• Click the Submit button

You're now ready to pair the unit to Homey!
