@chimera Hi and sure,
just tested a config which uses the values send by MQTT directly to decide which icon to display:
var mqttHook = [
{
mqttTopic: "magicmirror/tarrif/set",
mqttPayload: [
{
mqttNotiCmd: ["energy_tarrif_value"]
}
]
}
];
var mqttNotiCommands = [
{
commandId: "energy_tarrif_value",
notiID: "ENERGY_TARRIF"
}
];
module.exports = { mqttHook, mqttNotiCommands};
{
module: "MMM-MQTTbridge",
disabled: false,
config: {
mqttServer: "mqtt://my_user:my_pass@my_server:the_port",
mqttConfig: {
listenMqtt: true,
},
}
},
{
module: "MMM-ValuesByNotification",
position: "top_left",
header: "Energy",
config: {
updateInterval: 10,
reuseCount: 90,
valuePositions: "i",
valueNaPositions: "i",
itemPositions: "e",
groupPositions: "e",
groups: [
{
items: [
{
notification: "ENERGY_TARRIF",
valueImgIcon: "modules/MMM-ValuesByNotification/icons/tom.jpg",
values: [
{
jsonpath: "state",
thresholds: [
{
type: "eq",
value: "PEAK",
valueImgIcon: "modules/MMM-ValuesByNotification/icons/peak.jpg",
},
{
type: "eq",
value: "OFF-PEAK",
valueImgIcon: "modules/MMM-ValuesByNotification/icons/off-peak.jpg",
},
{
type: "eq",
value: "NIGHT",
valueImgIcon: "modules/MMM-ValuesByNotification/icons/night.jpg",
},
]
},
]
},
]
},
]
},
},
Explanation…
MMM-MQTTbridge:
The module connects to the MQTT-Server my_server to port the_port with user my_user and password my_pass
As listenMqtt is set to true the settings in mqttDictionary.js are used which results in:
If a message to mqttTopic magicmirror/tarrif/set is received the message is processed by the mqttNotiCmd energy_tarrif_value
As no payloadValue is specified the command is called independent of the message that is send to the topic
As no notiPayload is set in the command configuration but the notiID ENERGY_TARRIF every time a message is received of the specified topic a notification is send to all other modules with notification id ENERGY_TARRIF and the original MQTT message as payload
MMM-ValuesByNotification:
the module refreshes every ten seconds as updateInterval is set to 10
if no new notification is received for a configured notification of a item but the module refreshes it will reuse the last received value for a maximum of 90 times (reuseCount)
As valuePositions and valueNaPositions are set to i only a specified icon will be displayed instead of the value itself (which will be v or if both should be displayed vi; see Positions-Documentation for more info)
As itemPositions and groupPositions are both set to e only the elements and no additional titles (t) or icons (i) are displayed ( see Positions-Documentation for more info)
A single group with one item which contains one value is specified
The values of the item use the payload of the notification with id ENERGY_TARRIF
As default icon a image for the value (valueImgIcon) is used which has the path modules/MMM-ValuesByNotification/icons/tom.jpg (see Icon-Documentation for more details)
The value element selects the content with jsonpath state as its value. This means the payload of the notification is parsed as JSON and the value which is used in further processing is the content of the state element. This can be everything the HomeAssistant sends but should be either PEAK, OFF_PEAK or NIGHT
As there are thresholds specified they are validated against the previously selected state
If the payload is equal to (eq) to the value PEAK the path of the valueimgIcon is changed to modules/MMM-ValuesByNotification/icons/peak.jpg
If the payload is equal to (eq) to the value OFF_PEAK the path of the valueimgIcon is changed to modules/MMM-ValuesByNotification/icons/off-peak.jpg
If the payload is equal to (eq) to the value NIGHT the path of the valueimgIcon is changed to modules/MMM-ValuesByNotification/icons/night.jpg
Directly after the start the MMM-ValuesByNotification module will display the default icon. Every 10 seconds it refreshes. If a message for the specified topic is received by MMM-MQTTbridge the notification is send. The next time the module refreshes it will validate the message content and changes the icon depending on the content.
