Control

Available properties to set

Property	Info	Range
R	Red channel	0-255
G	Green channel	0-255
B	Blue channel	0-255
W1	White 1 channel	0-255
W2	White 2 channle	0-255
duration	Number of milliseconds used to fade to new state	0 - 100000000 (1.2 days)

Each channels fading is handled separatly, this means that it's possible to execute multiple fade event with different duration separatly for each channel.

Example: The following JSON will change the Red channel to max and Green to min over 5 seconds.

{
  "R": 255,
  "G": 0,
  "duration": 5000
}

MQTT

By sending JSON encoded string to the MQTT topic {id}/set, where id is either the unique chip id value or the configured alias, it's possible to control the channels. The MQTT topic {id}/updated will be emitted when changes are made for any of the channels.

HTTP POST

By sending JSON encoded string to the /status page it's possible to controll the channels.

HTTP GET

By doing and HTTP GET on the /status page and providing HTML encoded variable, example /status?R=255&W1=0&duration=5000, it is possible to set the values.

HTTP Page control

The device has an builtin webserver that allows both controlling the PWM channels and updating the MQTT configuration.

Configuration

Updating

MQTT parameters can both be set during WiFi setup and run-time by posting using REST API to /config

Property	Type	Info
mqtt_alias	String	Prefix to use for MQTT topic, if not set Chip ID will be used
mqtt_server	String	Server address
mqtt_port	String	Server port, default value 1883
mqtt_login	String	Server login
mqtt_passw	String	Server password, will be hidden over REST

Reset

It's possible to reset the H801 device to initial setup by sending and HTTP DELETE to /config twice under 5 seconds. This will reset both the configuration and the WiFi credentials.
