A lua script for pms7003 is incorrect

[zhuyuanxue]

commandArray = {}

if devicechanged['Dust'] then

local device = otherdevices_svalues["Dust"]
print(device)

local pm1, pm25, pm10

_,_,pm1, pm25, pm10 = string.find(device, "(.+);(.+);(.+)")

print(pm1) --show temp in LOG
print(pm25) --show humidity in LOG
print(pm10) --show humstat in LOG,


commandArray[1] = {['UpdateDevice'] = 10 .. '|0|' .. pm25}
commandArray[2] = {['UpdateDevice'] = 11 .. '|0|' .. pm10}

end
return commandArray


It doesn't work.
Can someone help me?

Hi zhuyuanxue,

you split your string and write it in your variables as string.
In my opinion the sensor would like to be updated with a number. And your IDX you can set in string section, or use otherdevices_idx[] instead.
So, this should work:

Code: Select all

commandArray = {}

device = otherdevices_svalues["Dust"]
print(device)

local pm1, pm25, pm10

_,_,pm1, pm25, pm10 = string.find(device, "(.+);(.+);(.+)")

print(pm1) --show temp in LOG
print(pm25) --show humidity in LOG
print(pm10) --show humstat in LOG,


if devicechanged['Dust'] then
	commandArray[1] = {['UpdateDevice'] = '10|0|'..tonumber(pm25)}
	commandArray[2] = {['UpdateDevice'] = '11|0|'..tonumber(pm10)}
end

return commandArray
