NetworkPowerPort:

host: 'http://192.168.0.42/relay/{index}/value'
index: 3
Will do a GET request to http://192.168.0.42/relay/3/value to get current
relay state, expecting a response of either '0' (relay off) or '1' (relay
on), and a PUT request to http://192.168.0.42/relay/3/value with request
data of '0' or '1' to change relay state.
