Graph question

[JimmyH1969]

Hi,

I have a Custom Sensor in Domoticz that counts the infected corona people. In Domoticz this works fine.

Domoticz counter.jpg (19.37 KiB) Viewed 1160 times

In the Dashticz i added it as a graph but the counter in the upper left corner is always 0,0 and is not updated.

Any clue?

Can't answer your question, but how did you set up this sensor in Domoticz?

Getting the data from: https://coronavirus-19-api.herokuapp.com/all
This will give you: {"cases":279338,"deaths":11587,"recovered":92906}

Ad some LUA code to parse the values and update a custom sensor with the values, like this:

Code: Select all

Debug = "On"

if Debug == "On" then
print "LUA-Corona Executed"
end

JSON  = (loadfile "C:\\Program Files (x86)\\Domoticz\\scripts\\lua\\JSON.lua")()

function docorona(filename, ctype1, ctype2, ctype3)

    file = io.open(filename, "r")
    json_text = file:read()
    file:close()
    corona = JSON:decode(json_text)
    
    commandArray[1]={['UpdateDevice']=ctype1..'|0|'..corona.cases}
    commandArray[2]={['UpdateDevice']=ctype2..'|0|'..corona.deaths}
    commandArray[3]={['UpdateDevice']=ctype3..'|0|'..corona.recovered}
    
        if Debug == "On" then
            print (tostring "Cases=" ..corona.cases.. " Deaths=" ..corona.deaths.. " recovered=" ..corona.recovered)
        end
    
end

function docoronaNL(filename, cnltype1, cnltype2, cnltype3)
    
    file = io.open(filename, "r")
    json_text = file:read()
    file:close()
    coronanl = JSON:decode(json_text)
    
        if Debug == "On" then
            print (tostring "CasesNL=" ..coronanl.cases.. " DeathsNL=" ..coronanl.deaths.. " recoveredNL=" ..coronanl.recovered)
        end
    
end

-- run the function and update the corresponding IDX
    docorona("corona.txt", 927, 925, 926)
    
    docoronaNL("coronaNL.txt", 1927, 1925, 1926)



return commandArray

I do this on Windows btw.
If you want the numbers from a specific country, you can do vor example:
https://coronavirus-19-api.herokuapp.co ... etherlands

I run this scheduled on a windows machine and output it to a .txt file in the domoticz folder.

Thanks!

I have domoticz running on synology nas server.
How do I set up reading in the LUA script https://coronavirus-19-api.herokuapp.co ... s/Slovakia

[JimmyH1969]

No idea, i'm running on windows.

I made a bash script for world wide statistics.
With a litte editing you can use it for your own country.
I saved the file into /home/pi/domoticz/scripts/sh/corona_stats.sh

Code: Select all

#!/bin/bash

# /home/pi/domoticz/scripts/sh/corona_stats.sh
# Make 3 virtual sensors in Domoticz and name them WW_Cases, WW_Deaths and WW_Recovered
# Note the three IDX numbers of the counters and fill them into CASES_IDX, DEATHS_IDX, RECOVERED_IDX
# Make a SSH connection with your domoticz device and start crontab -e
# Put the rule below into crontab and save it
# * * * * * /home/pi/domoticz/scripts/sh/corona_stats.sh
# Now every minute there will be an update of the stats.

# Settings
CORONA_STATS_WEBSITE="https://coronavirus-19-api.herokuapp.com/all"  # Corona stats website
DOMO_IP="192.168.1.100"                                              # Domoticz IP (e.g. 192.168.1.100)
DOMO_PORT="8080"                                                     # Domoticz port (e.g. 8080)
CASES_IDX='855'                                                      # Domoticz IDX number of cases
DEATHS_IDX='856'                                                     # Domoticz IDX number of deaths
RECOVERED_IDX='857'                                                  # Domoticz IDX number of recovered
 
# Get data from Corona website
INPUT=$(curl "$CORONA_STATS_WEBSITE")
CASES=$(echo "$INPUT" | awk -v FS="(:|,)" '{print $2//['}']/}')
DEATHS=$(echo "$INPUT" | awk -v FS="(:|,)" '{print $4//['}']/}')
RECOVERED=$(echo "$INPUT" | awk -v FS="(:|,)" '{print $6//['}']/}')

echo
echo Number of infections.: $CASES
echo Number of deaths.....: $DEATHS
echo Number of recovered..: $RECOVERED

# Load data in domoticz
curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$CASES_IDX&nvalue=0&svalue=$CASES"
curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$DEATHS_IDX&nvalue=0&svalue=$DEATHS"
curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$RECOVERED_IDX&nvalue=0&svalue=$RECOVERED"

I use a DzVent script. It's simpler and more or less standalone (apart from the custom sensor).

Spoiler: show

return {
on = {
timer = { 'every hour' },
httpResponses = { 'coronaRetrieved' }
},
execute = function(domoticz, item)
if (item.isTimer) then
domoticz.openURL({
url = 'https://coronavirus-19-api.herokuapp.com/all',
method = 'GET',
callback = 'coronaRetrieved'
})
elseif (item.isHTTPResponse) then
if (item.ok) then -- statusCode == 2xx
local current = item.json.cases
domoticz.log(item.json.cases)
domoticz.devices('Corona Cases').updateCustomSensor(item.json.cases)
domoticz.log(item.json.deaths)
domoticz.devices('Corona Deaths').updateCustomSensor(item.json.deaths)
domoticz.log(item.json.recovered)
domoticz.devices('Corona Recovered').updateCustomSensor(item.json.recovered)
end
end
end
}

It retrieves the data for the whole word. It can be easily adapted for specific countries though.

Nice, now let's hope the "cases" and "deaths" counters stop counting real soon....
