Lua Script tu update a device with json url -help

Hi, I'm writing a lua script to update a instant WATT counter but I doesn't work.. I think that there is a mistake in json url :cry:

Code: Select all

commandArray = {}
if devicechanged['Luci Cancellino'] == 'On'    then  cancellin = 50 else  cancellin = 0 end
if devicechanged['Facciata'] == 'On'           then  facciata = 21  else  facciata = 0 end
if devicechanged['Cupola Esterno'] == 'On'     then  dome = 8       else  dome = 0 end
if devicechanged['Corridoio'] == 'On'          then  hall = 10      else  hall = 0 end
if devicechanged['Cupola Xmas'] == 'On'        then  cupXmas = 500  else  cupXmas = 0 end
if devicechanged['Cancellino Xmas'] == 'On'    then  canXmas = 400  else  canXmas = 0 end
if devicechanged['Lampada Sala'] == 'On'       then  sala = 10      else  sala = 0 end
if devicechanged['Faro dietro'] == 'On'        then  farodie = 35   else  farodie = 0 end
if devicechanged['Faro davanti'] == 'On'       then  farodav = 40   else  farodav = 0 end
if devicechanged['Lanterna facciata'] == 'On'  then  lantfac = 16   else  lantfac = 0 end
if devicechanged['Lanterna nonna'] == 'On'     then  lantnon = 25   else  lantnon = 0 end
if devicechanged['Accento ingresso'] == 'On'   then  accing = 8     else  accing = 0 end
if devicechanged['Lampione'] == 'On'           then  lampion = 23   else  lampion = 0 end
if devicechanged['Presa Volante'] == 'On'      then  presvol = 300  else  presvol = 0 end
if devicechanged['Luce Garage'] == 'On'        then  lucgar = 4     else  lucgar = 0 end

watt= cancellin+facciata+dome+hall+cupXmas+canXmas+sala+farodie+farodav+lantfac+lantnon+accing+lampion+presvol+lucgar 

os.execute("curl 'http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx=45&nvalue=0&svalue={.watt}' " )
return commandArray
Could you help me? :P

It looks like your quotes in the os.execute are not correct as your variable watt will not be seen as you have placed the quotes.

Code: Select all

commandArray = {}
if devicechanged['Luci Cancellino'] == 'On'    then  cancellin = 50 else  cancellin = 0 end

Why use Json?
Can't you just use an UpdateDevice?

now the counter isn't red but it still has 0 value :shock: obvious I turned on some switch :lol:
where's the mistake? :cry:

Update device/sensor values using commandArray['UpdateDevice']='idx|nValue|sValue'

try

Code: Select all

print(watt)
to know the watt value
and try

Code: Select all

commandArray[1] = {['UpdateDevice'] = "45|0|100"}
to set at 100 manually the sValue

Seems that it doesn't like watt= a+b+c+d+e... etc :?

and when you set at 100 manually the sValue ?

yes, if I put

works :roll:

there are no errors in the log, 0 to the counter.. I think the script does not properly perform the sum of watts :?

When the script is called only one device will have changed so you can simplify your script by using elseif and just set watt directly.

Code: Select all

commandArray = {}

watt = 0

if devicechanged['Luci Cancellino'] == 'On'    then  watt = 50
elseif devicechanged['Facciata'] == 'On'           then  watt = 21
elseif devicechanged['Cupola Esterno'] == 'On'     then  watt = 8
elseif devicechanged['Corridoio'] == 'On'          then  watt = 10
elseif devicechanged['Cupola Xmas'] == 'On'        then  watt = 500
elseif devicechanged['Cancellino Xmas'] == 'On'    then  watt = 400
elseif devicechanged['Lampada Sala'] == 'On'       then  watt = 10
elseif devicechanged['Faro dietro'] == 'On'        then  watt = 35
elseif devicechanged['Faro davanti'] == 'On'       then  watt = 40
elseif devicechanged['Lanterna facciata'] == 'On'  then  watt = 16
elseif devicechanged['Lanterna nonna'] == 'On'     then  watt = 25
elseif devicechanged['Accento ingresso'] == 'On'   then  watt = 8 
elseif devicechanged['Lampione'] == 'On'           then  watt = 23
elseif devicechanged['Presa Volante'] == 'On'      then  watt = 300
elseif devicechanged['Luce Garage'] == 'On'        then  watt = 4
end

commandArray['UpdateDevice'] = "45|0|" .. tostring(watt)

return commandArray

Thinking about suspect this is not what you want, you are looking to sum the energy of each device to get total energy being used.

To make a sum you are going to need to store the sum as a user variable, then add to this each time a device is switched on and subtract from it each time a device is switched off.

@simonrg Exactly! :)

How can I do this?

The other way to do it is to test the devices each time any device changes or once a minute, which may be simpler.

Probably best to have this as time script rather than a device script, then it will only update every minute, rather every time anything changes.

Code: Select all

-- script_device_power_frequent.lua - a device type for the lua script will do the sum every time any device changes
-- script_time_power_every_minute.lua - a time type for the lua script will do the sum only every minute
commandArray = {}

watt = 0

if otherdevices['Luci Cancellino'] == 'On'    then  watt = watt +  50 end
if otherdevices['Facciata'] == 'On'           then  watt = watt +  21 end
if otherdevices['Cupola Esterno'] == 'On'     then  watt = watt +  8 end
if otherdevices['Corridoio'] == 'On'          then  watt = watt +  10 end
if otherdevices['Cupola Xmas'] == 'On'        then  watt = watt +  500 end
if otherdevices['Cancellino Xmas'] == 'On'    then  watt = watt +  400 end
if otherdevices['Lampada Sala'] == 'On'       then  watt = watt +  10 end
if otherdevices['Faro dietro'] == 'On'        then  watt = watt +  35 end
if otherdevices['Faro davanti'] == 'On'       then  watt = watt +  40 end
if otherdevices['Lanterna facciata'] == 'On'  then  watt = watt +  16 end
if otherdevices['Lanterna nonna'] == 'On'     then  watt = watt +  25 end
if otherdevices['Accento ingresso'] == 'On'   then  watt = watt +  8 end
if otherdevices['Lampione'] == 'On'           then  watt = watt +  23 end
if otherdevices['Presa Volante'] == 'On'      then  watt = watt +  300 end
if otherdevices['Luce Garage'] == 'On'        then  watt = watt +  4 end

commandArray['UpdateDevice'] = "45|0|" .. tostring(watt)

return commandArray
EDIT - corrected watt = watt to watt = 0

The error messages are quite helpful to pick up small errors.

What it is telling you is that on line 10 of script_device_power_frequent.lua there is a variable called watt which hasn't got a value.

Line 10 is watt = watt, if you look further up the script then you can see that watt hasn't been set before, hence watt has no value at this point, also watt = watt doesn't look right.

So line 10 should be watt = 0, this sets watt prior to doing the summing further on, hence watt is not used before its value is set.
