Hi Emontnemery, according to adrr 10: Integrations that communicate with devices and/or services are only configured via the UI.

Does this mean that I should rewrite the whole set of remote-io integrations to support config flows instead of yaml in this case?

[emontnemery]

@antonverburg ADR 10 states: GPIO is given as an example of integrations which should be configured via YAML:

Integrations that integrate transports. These integrations allow users to define their own protocol. Examples include MQTT, serial, GPIO.

Hence, remote_rpi_gpio falls under the type of integration where YAML is allowed.
