Read JSON data and update level blind [Solved]

[djdevil]

Hi everyone, I'm using a python script to issue commands and a bluethoot roller shutter engine.

The script by running this command:

Code: Select all

curl -i http://192.168.1.29:5000/AM43BlindsAction/CheckStatus

gives me this output

Code: Select all

HTTP/1.0 200 OK
Content-Type: text/html; charset=utf-8
Content-Length: 193
Server: Werkzeug/1.0.0 Python/3.7.3
Date: Sun, 16 Feb 2020 18:30:15 GMT

{
    "Tenda bagno": [
        {
            "battery": 78,
            "light": 0,
            "macaddr": "02:A0:07:6A:94:8D",
            "position": 99
        }
    ],
    "status": "OK"
}

is it possible to create a script that extrapolates the given "position" value and updates the idx every 5 minutes? thanks in advance for the help

there is no one you can help me thanks

Sure someone can. But what kind of idx should be updated every 5 minutes ? Is it a switch, or a text device a uservariable maybe ? Please do not expect forum member to read your mind

you are right, sorry!
the idx is Blinds Percentage Inverted

you are right, sorry!
the idx is Blinds Percentage Inverted

Could be something like

Code: Select all

local scriptVar = 'blindPosition'

return 
{
    on = 
    {
        timer = 
        {
            'every 5 minutes',
        },

        httpResponses = 
        {
            scriptVar
        },
    },

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

    execute = function(dz, item)

        if item.isTimer then
            dz.openURL({
                url = 'http://192.168.1.29:5000/AM43BlindsAction/CheckStatus',
                callback = scriptVar,
            })
            return
        end

        if item.ok then
            local blind = dz.devices('Tenda bagno') -- Change to name of domoticz device 
            local rt = item.json
            local position = rt['Tenda bagno'][1].position
            dz.log('Position of blind is ' .. position, dz.LOG_DEBUG
            blind.dimTo(position).silent()
        else
           dz.log('There was a problem handling the request', dz.LOG_ERROR)
           dz.log(item, dz.LOG_ERROR)
        end
    end
}

Not work this is my debug log:

Probably the response of your Bluetooth does not tell domoticz it returns a json. Can you try this one ?

Code: Select all

local scriptVar = 'blindPosition'

return 
{
    on = 
    {
        timer = 
        {
            'every 5 minutes',
        },

        httpResponses = 
        {
            scriptVar
        },
    },

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

    execute = function(dz, item)

        if item.isTimer then
            dz.openURL({
                url = 'http://192.168.1.29:5000/AM43BlindsAction/CheckStatus',
                callback = scriptVar,
            })
            return
        end

        if item.ok then
            local blind = dz.devices('Tenda bagno') -- Change to name of domoticz device 
            local rt = dz.utils.fromJSON(item.data)
            if rt == nil then 
                dz.log(item, dz.LOG_ERROR) 
                return 
            end
            local position = rt['Tenda bagno'][1].position
            dz.log('Position of blind is ' .. position, dz.LOG_DEBUG
            blind.dimTo(position).silent()
        else
           dz.log('There was a problem handling the request', dz.LOG_ERROR)
           dz.log(item, dz.LOG_ERROR)
        end
    end
}

can the 95% position be reversed? actually it would be 5% on the switch

I solved it like this!

Code: Select all

blind.dimTo(101-position).silent()

thanks waaren for the help you have given to me and that you give to the domoticz community every day
