.rain return 0

Post by hestia »

In DzVents docs
Rain meter
rain: Number (please note that this does return the rain total for today)
rainRate: Number
If the value of the counter in less than 1, the .rain returns 0, the value on the device (sValue) is OK
If the value is greater then 1, event though we put value w 1 decimal, it could returns a value w a lot of decimals
The value shows in the GUI is less than the value in the device (sValue)

A script the test

Code: Select all

For the rain: "Number (please note that this does return the rain total for today" I need to wait for tomorrow the see if it is today or not ; idem for sValue

Re: .rain return 0

Post by hestia »

More info...
First in the DzVents doc:
Rain meter
rain: Number (please note that this does return the rain total for today)
rainRate: Number
updateRain(rate, counter): Function. (rate in mm * 100 per hour, counter is total in mm)
rain is the rain of the day
counter is the total rain of the counter from the begining of the counter
So not easy!
This function gives the total rain of the counter
local function RainTot (p_id)
local f_rainValTable = _u.stringSplit(dz.devices(p_id).sValue,';')
local f_rainTot
if f_rainValTable[2] ~= nil then
f_rainTot = math.ceil(f_rainValTable[2] * 10) / 10
else
f_rainTot = 0
end
logWrite('Rain Tot = ' .. f_rainTot, dz.LOG_DEBUG)
return f_rainTot
end
After we have to had to this value the delta.
But usually rain meters give the value of the day...
So I keep the raintot at the beginning of the day with something like this (part of a script as an example)

Code: Select all

                                local newDay

                                if dz.devices(dev_PWS_rain).lastUpdate.isToday then
                                    logWrite('Same day')
                                    newDay = false
                                else
                                    logWrite('New day', dz.LOG_FORCE)
                                    newDay = true
                                end 

                                if dz.data.PWS_rainTotalOh == nil then
                                    logWrite(WU_Station .. ' dz.data.PWS_rainTotalOh NIL', dz.LOG_ERROR)
                                end
                                
                                if newDay or dz.data.PWS_rainTotalOh == nil then
                                    dz.data.PWS_rainTotalOh = RainTot(dev_PWS_rain) -- save rain tot at the beg of the day
                                    logWrite(WU_Station .. ' rain total at beg of the day: ' .. dz.data.PWS_rainTotalOh, dz.LOG_FORCE)
                                end
After just add the rain of the day to the rain tot at the beg of the day and update the device like

Code: Select all

                                local w_rainTot = dz.data.PWS_rainTotalOh + WUPrecipTotal
                                logWrite(WU_Station .. ' rainTot: ' .. w_rainTot, dz.LOG_FORCE)
        			dz.devices(dev_PWS_rain).updateRain(WUPrecipRate*100,w_rainTot)
