Rpi3, zStick, newest beta.
I would like to turn on a wall socket for my garden pump. But only when the todays rain rate of my personal weather station is lower than 0.5. I have a virtual sensor called "Weatherstation_Todaysrain" the sensor shows the todays rain rate. My code doesn't work seems that I don't get the value.

Spoiler: show: ^{return {

on = {

timer = {'at 07:52','at 23:13 '

}

},

execute = function(domoticz, device)

if domoticz.devices('Weatherstation_Todaysrain').nValue <= 0.5 then

domoticz.devices('Wandstecker').switchOn().forMin(30)

end

end

}}

When calling the status with json I got

Spoiler: show: ^{ActTime 1564640893

The value you are looking for is likely to be stored in the sValue field (= rawData table in dzVents). Small complication is that it could be stored as a combination of the value (4.2) and the unit (mm) so we have carve out the value. In Lua you can use the string.match function for that.

Can you try this ?

Code: Select all

return {
    on = 
    {
        timer = 
        {
            'at 07:52',
            'at 23:13', 
        }
    },

    execute = function(domoticz)
        local floatFormat =  '%d*%.*%d*'
        local rawRainToday = domoticz.devices('Weatherstation_Todaysrain').rawData[1] -- '4.2 mm'
        local rainToday = tonumber(string.match(rawRainToday, floatFormat)) -- 4.2
    
        if rainToday <= 0.5 then
            domoticz.devices('Wandstecker').switchOn().forMin(30)
        end
    end
}

@waaren
Thank you very much! It worked as it should.
