dzVents - event on temperature increase

Hi, I have following dzVents function:
Code: Select all
return {
active = true,
on = {
devices = {
'temperature1', -- DS18B20 temperature sensor
'switch1', -- domoticz virtual switch
'thermostat1' -- domoticz temperature
},
},
execute = function(domoticz)
-- ...
If I switch on/off "switch1" or change value on "thermostat1", function execute - it is ok.
But when "temperature1" change value (I mesure every 1 minute) nothing happens.
It is very bad. I need to compare temperature and thermostat and if temeprature is too hight stop heating.
How can I write "run function when temeprature1 change value"?

It should call your function immediately as soon as the temperature changes. Something is wrong if that doesn't happen. Turn dzVents into debug logging mode and carefully watch the domoticz.log.

I wrote this script:
Code: Select all
return {
active = true,
logging = {
level = domoticz.LOG_DEBUG,
marker = "TEST_"
},
on = {
devices = {
'temperature1'
},
},
execute = function(domoticz, device)
domoticz.log("---aaaaaaaaaaaaaaaaaaaaaaaaa")
domoticz.log(device.name)
domoticz.log(device.temperature)
domoticz.log("---bbbbbbbbbbbbbbbbbbbbbbbbb")
end
}
I have DHT22 sensor. In Domoticz type
"Temperature + Humidity"
it works:
Code: Select all
2017-12-14 17:48:45.643 dzVents: Info: Handling events for: "temperature1", value: "11.15;54.10;0"
2017-12-14 17:48:45.644 dzVents: Info: TEST_: ------ Start internal script: temperature_test: Device: "temperature1 (test)", Index: 10
2017-12-14 17:48:45.644 dzVents: Info: TEST_: ---aaaaaaaaaaaaaaaaaaaaaaaaa
2017-12-14 17:48:45.644 dzVents: Info: TEST_: temperature1
2017-12-14 17:48:45.644 dzVents: Info: TEST_: 11.14999961853
2017-12-14 17:48:45.645 dzVents: Info: TEST_: ---bbbbbbbbbbbbbbbbbbbbbbbbb
2017-12-14 17:48:45.645 dzVents: Info: TEST_: ------ Finished temperature_test
But I have virtual domoticz thermometer, that extract only temperature from DHT22 "Temperature + Humidity". I'm using this code found something at domoticz wiki/forum:
Code: Select all
# /home/domoticz/domoticz/scripts/lua/script_device_DHT22.lua
-- http://www.domoticz.com/wiki/Virtual_weather_devices#Scraping_only_temperature
--Script To Parse WeatherUnderground Multi-Value Sensor, Additionally using PWS: system from WU with a new output format
--This script assumes the output (which can be viewed in events show current state button) is like this 19.5;79;3;1019;3 (temp;humidity;null;pressure;null)
--more details at this wiki http://www.domoticz.com/wiki/Virtual_weather_devices
--
--The following need updated for your environment get the 'Idx' or 'Name' off the Device tab. By default only the Temp is 'uncommented or enabled' in this script.
local sensorwu = 'dht22' --name of the sensor that gets created when you add the WU device (and that contains multiple values like temperature, humidity, barometer etc)
local idxt = 14 --idx of the virtual temperature sensor you need to change this to your own Device IDx
local idxh = 15 --idx of the virtual humidity sensor you need to change this to your own Device IDx
--local idxp = 999 --idx of the virtual pressure sensor you need to change this to your own Device IDx
--
commandArray = {}
if devicechanged[sensorwu] then
sWeatherTemp, sWeatherHumidity, sWeatherPressure = otherdevices_svalues[sensorwu]:match("([^;]+);([^;]+);([^;]+)")
sWeatherTemp = tonumber(sWeatherTemp)
sWeatherHumidity = tonumber(sWeatherHumidity)
sWeatherPressure = tonumber(sWeatherPressure)
parseDebug = ('WU Script Parsed Temp=' .. sWeatherTemp .. ' Humidity=' .. sWeatherHumidity .. ' Pressure=' .. sWeatherPressure)
print(parseDebug)
commandArray[1] = {['UpdateDevice'] = idxt .. '|0|' .. sWeatherTemp}
commandArray[2] = {['UpdateDevice'] = idxh .. '|' .. tostring(sWeatherHumidity) .. '|' .. tostring(sHumFeelsLike)}
--commandArray[3] = {['UpdateDevice'] = idxp .. '|0|' .. tostring(sWeatherPressure) .. ';' .. tostring(sWeatherPressForcast)}
end
return commandArray
This sdcript update value on domoticz widget, but cannot trigger change action in dzVents. How can I use this script-updated-virtual domotcz sensor?

Just update your virtual sensor. If you use dzVents 2.3 then updating the sensor should trigger the script:
Code: Select all
return {
active = true,
logging = {
level = domoticz.LOG_DEBUG,
marker = "TEST_"
},
on = {
devices = {
'temperature1',
'myVirtualTemperatureDevice'
},
},
execute = function(domoticz, device)
if (device.name == 'temperature1') then
domoticz.log('My temperature1 device got a new value: ' .. tostring(device.temperature))
-- update the virtual sensor:
domoticz.devices('myVirtualTemperatureDevice'). updateTemperature(device.temperature)
elseif (device.name == 'myVirtualTemperatureDevice') then
domoticz.log('My virtual temperature device got a new value: ' .. tostring(device.temperature))
end
end
}
