Barometer sensor
barometer. Number. Barometric pressure.
forecast: Number.
forecastString: String.
updateBarometer(pressure, forecast): Function. Update barometric pressure. Forecast can be domoticz.BARO_STABLE, BARO_SUNNY, BARO_CLOUDY, BARO_UNSTABLE, BARO_THUNDERSTORM.
Já bych tedy použil:
local hodnota_cidla = domoticz.devices('Moje_cidlo_tlaku').barometer
Nebo použít univerzální API pro všechny typy sensorů:
Device attributes and methods for all devices
active: Boolean. Is true for some common states like 'On' or 'Open' or 'Motion'. Same as bState.
batteryLevel: Number If applicable for that device then it will be from 0-100.
bState: Boolean. Is true for some common states like 'On' or 'Open' or 'Motion'. Better to use active.
changed: Boolean. True if the device was changed
description: String. Description of the device.
deviceId: String. Another identifier of devices in Domoticz. dzVents uses the id(x) attribute. See device list in Domoticz' settings table.
deviceSubType: String. See Domoticz devices table in Domoticz GUI.
deviceType: String. See Domoticz devices table in Domoticz GUI.
dump(): Function. Dump all attributes to the Domoticz log. This ignores the log level setting.
hardwareName: String. See Domoticz devices table in Domoticz GUI.
hardwareId: Number. See Domoticz devices table in Domoticz GUI.
hardwareType: String. See Domoticz devices table in Domoticz GUI.
hardwareTypeValue: Number. See Domoticz devices table in Domoticz GUI.
icon: String. Name of the icon in Domoticz GUI.
id: Number. Index of the device. You can find the index in the device list (idx column) in Domoticz settings. It's not truly an index but is unique enough for dzVents to be treated as an id.
idx: Number. Same as id: index of the device
lastUpdate: Time Object: Time when the device was updated.
name: String. Name of the device.
nValue: Number. Numerical representation of the state.
rawData: Table: All values are String types and hold the raw data received from Domoticz.
setDescription(description): Function. 2.4.16 Generic method to update the description for all devices, groups and scenes. E.g.: device.setDescription(device.description .. '/nChanged by '.. item.trigger .. 'at ' .. domoticz.time.raw). Supports command options.
setIcon(iconNumber): Function. 2.4.17 method to update the icon for devices. Supports command options.
setState(newState): Function. Generic update method for switch-like devices. E.g.: device.setState('On'). Supports command options.
setValues(nValue,[ sValue1, sValue2, ...]): Function. 2.4.17 Generic alternative method to update device nValue, sValue. Uses domoticz JSON API to force subsequent events like pushing to influxdb. nValue required but when set to nil it will use current nValue. sValue parms are optional and can be many.
state: String. For switches, holds the state like 'On' or 'Off'. For dimmers that are on, it is also 'On' but there is a level attribute holding the dimming level. For selector switches (Dummy switch) the state holds the name of the currently selected level. The corresponding numeric level of this state can be found in the rawData attribute: device.rawData[1].
signalLevel: Number If applicable for that device then it will be from 0-100.
switchType: String. See Domoticz devices table in Domoticz GUI (Switches tab). E.g. 'On/Off', 'Door Contact', 'Motion Sensor' or 'Blinds'
switchTypeValue: Number. See Domoticz devices table in Domoticz GUI.
timedOut: Boolean. Is true when the device couldn't be reached.
unit: Number. Device unit. See device list in Domoticz' settings for the unit.
update(< params >): Function. Generic update method. Accepts any number of parameters that will be sent back to Domoticz. There is no need to pass the device.id here. It will be passed for you. Example to update a temperature: device.update(0,12). This will eventually result in a commandArray entry
local hodnota_cidla = domoticz.devices('Moje_cidlo_tlaku').nValue
Pressure
pressure: Number.
updatePressure(pressure): Function.
local hodnota_cidla = domoticz.devices('Moje_cidlo_tlaku').pressure
local rozdil = domoticz.devices('Cidlo_po_vodou').barometer - domoticz.devices('Cidlo_venku').barometer
domoticz.devices('Hloubka').updateDistance(rozdil)
'Cidlo_po_vodou' a 'Cidlo_venku' jsou názvy čidel tlaku, které jste zadal v Domoticz při jejich vytváření.
'Hloubka' je název dummy senzoru vzdálenosti vytvořeném v Domoticz pro zobrazení hloubky.
Pokud máte pravidelný tvar nádrže, snadno pak můžete vypočítat objem vody a uložit do dummy senzoru ( typ custom s ozmačením jednotek m3 ) příkazem:
domoticz.devices('Objem_nadrze').updateCustomSensor(spocitany objem)
Případně objem nádrže v procentech s využitím senzoru procent:
domoticz.devices('Objem_v_procentech').updatePercentage(aktualni objem / maximalni objem * 100)
Když chcete akci provést každých pět minut, tak na začátek skriptu dáte:
return {
active = true, -- set to false to disable this script
on = {
timer = {
'every 5 minutes',
}
},
execute = function(domoticz)
Pokud naopak chcete provést při změně hodnoty:
return {
active = true, -- set to false to disable this script
on = {
devices = {
'Loznice_Setpoint'
}
},
execute = function(domoticz, device)
Třeba sepnutí spínače na dobu 5 minut je s DzVents jednoduché jak facka, v porovnání s počítáním uplynulého času v klasické LUA.
domoticz.devices('Muj_casovy_spinac').switchOn().forMin(5)
Bez využití skriptů budete Domoticz používat tak na 20% toho, co umí.
