So I am on OpenHAB v3.2.0 on OpenSUSE 15.3 (Raspberry Pi 4B) and I have created a new item:
openhab> openhab:items list WxTemperatureTrend
WxTemperatureTrend (Type=NumberItem, State=-0.07 °C, Label=Outside temperature trend, Category=temperature, Tags=[Temperature, Point], Groups=[WxCurrent])
…and a rule to update its value (uses JavaScript binding):
configuration: {}
triggers:
- id: "1"
configuration:
itemName: WxCurrent_Current_Temperature
type: core.ItemStateChangeTrigger
- id: "2"
configuration:
itemName: WxForecast_ForecastHours03_Temperature
type: core.ItemStateChangeTrigger
conditions: []
actions:
- inputs: {}
id: "3"
configuration:
type: application/javascript;version=ECMAScript-2021
script: >
function main () {
const v1 = items.getItem("WxForecast_ForecastHours03_Temperature").rawState;
const v0 = items.getItem("WxCurrent_Current_Temperature").rawState;
const diff = v1 - v0;
const hours = 3; // Difference between forecast and current timestamps
const trend = Math.round((diff/hours)*100)/100;
items.getItem("WxTemperatureTrend").postUpdate(trend);
};
main();
type: script.ScriptAction
Here’s just the script, with proper highlighting:
function main () {
const v1 = items.getItem("WxForecast_ForecastHours03_Temperature").rawState;
const v0 = items.getItem("WxCurrent_Current_Temperature").rawState;
const diff = v1 - v0;
const hours = 3; // Difference between forecast and current timestamps
const trend = Math.round((diff/hours)*100)/100;
items.getItem("WxTemperatureTrend").postUpdate(trend);
};
main();
The problem is that, as may be seen in the screenshot, the value is not showing in my sitemap:
This is roughly what the sitemap looks like:
sitemap default {
Frame label="Environment" {
Group label="Current weather" item=WxCurrent_Current_Temperature icon="sun_clouds" {
Text item=WxCurrent_Current_Temperature label="Temperature"
Text item=WxTemperatureTrend
Text label="Humidity" item=WxCurrent_Current_Humidity
Text label="Pressure" item=WxCurrent_Current_Pressure
Text item=WxCurrent_Current_Windspeed label="Wind speed"
Text item=WxCurrent_Current_Winddirection label="Wind direction"
Text item=WxCurrent_Current_Cloudiness label="Clouds"
Text item=WxCurrent_UVIndex label="UV index"
Text item=WxCurrent_Current_Condition label="Condition"
Text item=WxCurrent_ObservationTime
}
Any ideas what might be going on? I’m at a loss.
