+## Home Assistant
+Once you have your doorbell flashed with ESPHome and connected to Home Assistant, you should see the following services appear (if not, try power cycling the doorbell so that it reconnects to Home Assistant; I've found that the services don't seem to appear on first connect):
+
+| Service name  | Description | Parameter 1 | Parameter 2 |
+| ------------- | ----------- | ----------- | ----------- |
+| `esphome.linp_doorbell_linp_set_volume` | Set the volume (`0` to mute) | `volume` \[int, 0-4]  |  |
+| `esphome.linp_doorbell_linp_play_tune` | Play a tune/chime | `tune` \[int, 1-36]  |  |
+| `esphome.linp_doorbell_linp_learn_button` | Register a new button, setting its tune/chime to the specified value | `tune` \[int, 1-36]  |  |
+| `esphome.linp_doorbell_linp_set_tune` | Set the tune/chime for an already-registered button | `button` \[int, 1-10]  | `tune` \[int, 1-36] |
+| `esphome.linp_doorbell_linp_forget_button` | Unregister a button from this unit | `button` \[int, 1-10]  |  |
+| `esphome.linp_doorbell_linp_send_raw_command` | Enqueue a raw command to be sent to the STM8S005K6 | `command` \[string]  |  |
+
+Note that the `linp_doorbell` prefix on all service names is the name of your ESPHome node, as defined in the `esphome:` block of your yaml file.
