Problem with json-httpresponse (Solved)

[Backbone]

I get data from a web thermostat which I can access from an IP address.

In DZVENTS the code script checks 3 variables.
Only the code line with the temperature is working fine and can be shown in a dummy entry.
The code line with Humidity is not working and do not show any data change in the dummy entry.
The relay code line I commented for a later troubleshooting.
Could there be a simple reason I overlook?
The IDX value is correct.
Error log says only: Error: dzVents: Error: (3.1.8) ESP32: No status provided. Humidity not set

Thanks, Paco

To get some insight of what you receive try this:

Code: Select all

domoticz.utils.dumpTable(item.json)

and watch the log.

[Backbone]

If I understanding it correctly by adding it to the script this is the result.

2024-01-27 22:22:00.805 Error: dzVents: Error: (3.1.8) ESP32: No status provided. Humidity not set
2024-01-27 22:22:00.805 Error: dzVents: Error: (3.1.8) ESP32: An error occurred when calling event handler EPS32 T+H+R

[HvdW]

I suggest like this:

Code: Select all

-- temperature.updateTemperature(item.json.celsius)
-- humidity.updateHumidity(item.json.humidity)
-- relay.updateText(item.json.relay_high)
domoticz.utils.dumpTable(item.json)

Precede every line that causes trouble with comment signs like --

The script then gives you just the dump and you will be able to find how to select the dat you need.
You will see a dump like this one from wheatherlive

In this case we receive the temperature like this:

Code: Select all

domoticz.log('Outside temperature is   ' .. item.json.liveweer[1].temp,domoticz.LOG_DEBUG)

The dump informs you how to get the data you want to have.
And don't forget the domoticz.devices magic words like:

Code: Select all

domoticz.devices('NAME_OFYOUR_DEVICE').updateTemperature(item.json.liveweer[1].temp)

or

Code: Select all

domoticz.devices(32).updateTemperature(item.json.liveweer[1].temp)

Oh, last remark: replace my 'domoticz' with your 'dz' because that is how you tell your script to understand.

[Kedi]

You have to send status as well. See https://www.domoticz.com/wiki/DzVents:_ ... ity_sensor
And you have to calculate the status.

[habahabahaba]

Just rename 'domoticz' to 'dz' (as you call it in "execute = function(dz, item)" at line 37 and 41 )

And then catch other errors

[Backbone]

OK thanks for all suggestions I got one step further.
Domoticz is replaced with dz where needed.

Now the log spits the correct data for the script as HvdW suggested.

Then I tried to understand the logic that comes from HvdW his example but it throws an error.
Code used now

Code: Select all

local scriptVar = 'ESP32'

return
{
    on =
    {
        timer =
        {
            'every minute',
        },
        httpResponses =
        {
            scriptVar .. '*',
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- set to domoticz.LOG_ERROR when all OK
        marker = scriptVar,
    },

    execute = function(dz, item)
        --local temperature = dz.devices(32)       -- set to id of your virtual temperature sensor
        --local humidity = dz.devices(64)          -- set to id of your virtual humidity sensor
        --local relay = dz.devices(34)             -- set to id of your virtual text device
        if item.isTimer then
            dz.openURL(
            {
                url = '192.168.1.19',
                callback = scriptVar .. '_getJSON',
            })
    elseif item.isHTTPResponse and item.isJSON then
               domoticz.devices(32).updateTemperature(item.json.celsius)
            -- temperature.updateTemperature(item.json.celsius)
            -- humidity.updateHumidity(item.json.humidity)
            -- relay.updateText(item.json.relay_high)
            dz.utils.dumpTable(item.json)
            
        else
            dz.log('There was a problem handling the request', dz.LOG_ERROR)
            dz.log(item, dz.LOG_DEBUG)
        end
    end
}

It throws this as log...

The same error - DOMOTICZ
You had to use DZ!!

Overlooked Domoticz while copying code...>me bad

The temperature codeline runs fine as it did before in the old code but the humidity again errors in the same way.

The IDX 64 for humidity ESP32 is correct...

Did you read this: "You have to send status as well. See https://www.domoticz.com/wiki/DzVents:_ ... ity_sensor
And you have to calculate the status." by Kedi ?

When you are updatin humidity you have to use
updateHumidity(humidity, status)
Update humidity. status can be domoticz.HUM_NORMAL, HUM_COMFORTABLE, HUM_DRY, HUM_WET. Supports command options.

try
dz.devices(64).updateHumidity(item.json.humidity, status) or
dz.devices(64).update(item.json.humidity, status)

where status can be 0, 1, 2, 3
0 - normal
1 - comfort
2 - dry
3 - wet

Could be something simple as from my nodered flows.

Code: Select all

if (HUM < 30) {
    HUM_STAT=2;
} else if((HUM >= 30) && (HUM < 45)) {
    HUM_STAT=0;
} else if((HUM >= 45) && (HUM <= 70)) {
    HUM_STAT=1;
} else if(HUM >= 70) {
    HUM_STAT=3;
}

OK, guys thank you for leading me to the working solution.
For my general display purpose the Humidity Virtual device needed only a value to be reported from the thermostat data. That is all I needed.
But what I learned now from you is this device needs a value and a calculated status number to show the humidity in WORDS in the same virtual device. If one is missing it throws an error.
It was my assumption the status was coming automatically from the input data numbers.

I will add the status logic Kedi proposed.
Learned something new today.

Thank you all for the time taken, appreciate it very much.
Was bugging me a few months.
