No Problem Jan!!
First create a dummy virtual switch and create there a virutal switch of type "Warning" (Waarschuwing) with an approrpiate name (Hooikoorts???)
On the pi create the follwoing scirpt in /usr/local/bin:
Code: Select all

JSONFile='/tmp/HooikoortsJSONFile.json' # change to full qualified filename
domoticzPort=8080 # change to your domoticz port number
domoticzIP=127.0.0.1 # change to domoticz IP (keep 127.0.0.1 if local)

Add the following line to the crontab on your pi
Code: Select all
03 * * * * /usr/local/bin/hooikoorts
In Domoticz create a dzEvents (Timer) script). Replace the content of this with the following:
Code: Select all
local scriptName = 'Hooikoorts'
local scriptVersion = '1.0'
local alert_device = 1921 -- naam of idx van het apparaat (virtueel-> waarschuwing)
local risques = {
-- "Bomen", -- algemeen, niet gebruiken
"Els",
"Es",
"Beuk",
"Berk",
"Cipres",
"Iep",
"Hazelaar",
"Eik",
"Populier",
"Tamme Kastanje",
"Wilg",
-- "Grassen en kruiden", -- algemeen, niet gebruiken
"Ambrosia",
"Grassen",
"Bijvoet",
"Brandnetel",
"Weegbree",
"Rogge",
"Zuring",
}
return {
on =
{
customEvents =
{
'JSONHooikoortsFileReady',
}
},
logging = {
level = domoticz.LOG_DEBUG, -- options: LOG_INFO, LOG_ERROR, LOG_MODULE_EXEC_INFO
marker = scriptName..' v'..scriptVersion
},
data = {alertePollens = {initial = {} }, -- Keep a copy of last json just in case
},
execute = function(domoticz, item)
local function readFile(f)
local file = io.open (f, 'r') -- open file in read mode
local data = file:read('*a') -- read all
file:close()
return data
end
-- Read the file
local json = domoticz.utils.fromJSON(readFile(item.data))
-- Do we actually have data?
if #item.data > 0 then
domoticz.log("We have new accurate data.",domoticz.LOG_ERROR)
domoticz.data.alertePollens = json
rt = json
else
domoticz.log("Problem with response from Pollens (no data) using data from earlier run",domoticz.LOG_ERROR)
rt = domoticz.data.alertePollens -- json empty. Get last valid from domoticz.data
if #rt < 1 then -- No valid data in domoticz.data either
domoticz.log("No previous data. are Pollens url ok?",domoticz.LOG_ERROR)
return false
end
end
--Process the json file
local niveau1, niveau2, niveau3, niveau4, niveau5, text = '', '', '', '', '', ''
local riskLevel = rt.riskLevel -- this is the general risk level as given by weeronline
for k, risque in pairs(risques) do
for k, pollens in pairs(rt.risks) do
if pollens.pollenName == risque and pollens.level == 4 then niveau5 = niveau5.. " ".. pollens.pollenName.."," end
if pollens.pollenName == risque and pollens.level == 3 then niveau4 = niveau4.. " ".. pollens.pollenName.."," end
if pollens.pollenName == risque and pollens.level == 2 then niveau3 = niveau3.. " ".. pollens.pollenName.."," end
if pollens.pollenName == risque and pollens.level == 1 then niveau2 = niveau2.. " ".. pollens.pollenName.."," end
if pollens.pollenName == risque and pollens.level == 0 then niveau1 = niveau1.. " ".. pollens.pollenName.."," end
end
end
if niveau5 ~= '' then text, riskLevel = niveau5, 4
elseif niveau4 ~= '' then text, riskLevel = niveau4, 3
elseif niveau3 ~= '' then text, riskLevel = niveau3, 2
elseif niveau2 ~= '' then text, riskLevel = niveau2, 1
elseif niveau1 ~= '' then text, riskLevel = niveau1, 1
else text, riskLevel = "Geen Alert", 0
end
text = string.gsub (text, ",$", "") -- remove the "," at the end
local Kans
if riskLevel == 4 then Kans="Zeer groot" end
if riskLevel == 3 then Kans="Groot" end
if riskLevel == 2 then Kans="Matig" end
if riskLevel == 1 then Kans="Klein" end
if riskLevel == 0 then Kans="Zeer klein" end
MessageText = "Kans " .. Kans .. " bij " .. text
if alert_device ~= nil then
domoticz.devices(alert_device).updateAlertSensor(riskLevel, MessageText)
end
end
}
Save it and switch it on
That should do the trick.
The script gets the info from the weeronline webpage. Creates a json file and sends it to Domoticz . Domoticz picks it up, processes the json file, and updates the virtual sensor. The code is bases on the code which you can find at
https://pon.fr/dzvents-alerte-pollens/ I just made it work for weeronline.
Hope you will enjoy it as much as I do (thanks to our French friend).
PS: the implementation for migraine and rheumatism is more or less the same. If interested, let me know, happy to share the code.
