Hi. I have a problem with a script that gets a value from api ethermine (https://api.ethermine.org/) . The script returns 0 value. If i asks other api, e.g. https://corona.lmao.ninja/v3/covid-19/c ... s/slovakia the script returns valid values.

Code: Select all

return {
    on = {
        timer = { 'every 1 minutes' },
         system = {
            'start',
        },
        httpResponses = { 'currentHashrate' }
    },
    execute = function(domoticz, item)
        if (item.isTimer) then
            domoticz.openURL({
                url = 'https://api.ethermine.org/miner/mymineraddress/currentStats/',
                method = 'GET',
                callback = 'currentHashrate'
            })
        end

        if (item.isHTTPResponse and item.ok) then
            domoticz.devices('Hashrate').updateCustomSensor(item.json['currentHashrate'])
        end
    end
}

When I use the HTTP call from the script ( https://api.ethermine.org/miner/myminer ... rentStats/ ), the response is

Code: Select all

{
      "status": "ERROR",
       "error": "Invalid address"
}

so I assume your HTTP cal is different. What do you see when you enter that other one in the browser address bar?

you need to replace "mymineraddress" with your wallet address. E.g https://api.ethermine.org/miner/0xEAC84 ... rentStats/

and the resoponse is

Code: Select all

{"status":"OK","data":{"time":1616700600,"lastSeen":1616700568,"reportedHashrate":1415928031,"currentHashrate":1415055555.5555553,"validShares":1269,"invalidShares":0,"staleShares":7,"averageHashrate":1392374999.9999993,"activeWorkers":6,"unpaid":27800501218674976,"unconfirmed":null,"coinsPerMin":0.00005827565773093277,"usdPerMin":0.09365422678280473,"btcPerMin":0.0000018088764159681532}}

The value you are looking for is a level deeper in the JSON.

Can you try this one?

Code: Select all

local scriptVar = 'currentHashrate'

return
{
    on =
    {
        timer =
        {
            'every 1 minutes', -- change to required frequency
        },
        httpResponses =
        {
            scriptVar,
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG,  -- set to domoticz.LOG_ERROR when all ok
        marker = 'miner',
    },

    execute = function(domoticz, item)
        if item.isTimer then
            domoticz.openURL(
            {
                url = 'https://api.ethermine.org/miner/mymineraddress/currentStats/',
                callback = scriptVar,
            })
        end

        if (item.isHTTPResponse and item.ok) then
            domoticz.devices('Hashrate').updateCustomSensor(domoticz.utils.round(item.json.data.currentHashrate, 3))
        end
    end
}

Now works. Thank you very much. I have one more question, the return value is in this form 1.99167e+08. But when I set my virtual device to "text", and raplece "domoticz.devices('Hashrate').updateCustomSensor(domoticz.utils.round(item.json.data.currentHashrate, 3))" to "domoticz.devices('Hashrate').updateText(domoticz.utils.round(item.json.data.currentHashrate, 3))" the value is correct 199166666.6667. How can I covert floating value to an integer? Sorry but my domoticz skills are very limited.

the conversion to scientific notation is something that is done deeper in domoticz for counter- and custom sensor type of devices. This cannot be influenced by dzVents.

Conversion (which will obviously include rounding) to integer in dzVents (= Lua) can be done using the math.floor() function.

Code: Select all

domoticz.devices('Hashrate').updateCustomSensor(math.floor(tonumber(item.json.data.currentHashrate) + 0.5))

or

Code: Select all

domoticz.devices('Hashrate').updateText(math.floor(tonumber(item.json.data.currentHashrate) + 0.5))
