Husqvarna lawn robot mover API

[pioneersteffen]

Hi Admin,

many thanks for your help and feedback.

I tried to implement your hints:

Code:

local https = require('ssl.https')
local json = require('json')

-- Husqvarna Authentication API
local authEndpoint = 'https://api.authentication.husqvarnagroup.dev/v1/oauth2/token'
local clientId = 'xxx'
local clientSecret = 'xxx'

-- Husqvarna Automower Connect API
local connectEndpoint = 'https://api.amc.husqvarna.dev/v1/mowers/ba15739b-0449-411a-9eb9-9ad866362075/actions'
local accessToken

-- Funktion zum Erhalten eines Zugriffstokens
function getAccessToken()
    local requestBody = 'grant_type=client_credentials'
        .. '&client_id=' .. clientId
        .. '&client_secret=' .. clientSecret

    local response_body = {}
    local _, code, _, _ = https.request{
        url = authEndpoint,
        method = 'POST',
        headers = {
            ['Content-Type'] = 'application/x-www-form-urlencoded',
            ['Content-Length'] = #requestBody
        },
        source = ltn12.source.string(requestBody),
        sink = ltn12.sink.table(response_body)
    }

    if code == 200 then
        local response = table.concat(response_body)
        local jsonResponse = json.decode(response)
        accessToken = jsonResponse.access_token
    else
        -- Fehlerbehandlung
        log('Fehler beim Abrufen des Zugriffstokens:', code)
    end
end

-- Funktion zum Senden des Startbefehls
function sendStartCommand()
    local requestBody = '{"type: 'Start', attributes: { duration: 24 // minutes}'

    local response_body = {}
    local _, code, _, _ = https.request{
        url = connectEndpoint,
        method = 'POST',
        headers = {
            ['Authorization'] = 'Bearer ' .. accessToken,
            ['X-Api-Key'] = clientId,
            ['Authorization-Provider'] = 'husqvarna',
            ['Content-Type'] = 'application/vnd.api+json',
            ['Content-Length'] = #requestBody
        },
        source = ltn12.source.string(requestBody),
        sink = ltn12.sink.table(response_body)
    }
   
log (code, status, headers, response_body)



    if code == 200 then
        -- Erfolgreich gestartet
        log('Automower wurde gestartet.')
    else
        -- Fehlerbehandlung
        log('Fehler beim Starten des Automowers:', code)
    end
end

-- Funktion zum Senden des Stopbefehls
function sendStopCommand()
    local requestBody = '{"name": "stop"}'

    local response_body = {}
    local _, code, _, _ = https.request{
        url = connectEndpoint,
        method = 'POST',
        headers = {
            ['Authorization'] = 'Bearer ' .. accessToken,
            ['X-Api-Key'] = clientId,
            ['Authorization-Provider'] = 'husqvarna',
            ['Content-Type'] = 'application/json',
            ['Content-Length'] = #requestBody
        },
        source = ltn12.source.string(requestBody),
        sink = ltn12.sink.table(response_body)
    }
    log (code, status, headers, response_body)



    if code == 200 then
        -- Erfolgreich gestoppt
        log('Automower wurde gestoppt.')
    else
        -- Fehlerbehandlung
        log('Fehler beim Stoppen des Automowers:', code)
    end
end

-- Beispielaufrufe
getAccessToken()
sendStartCommand()

Unfortunately I getting the following failure:

Code:

string: {"errors":[{"id":"e9f44309-1dfb-48bf-a0b3-dcab8111951d","status":"500","code":"internal.error","title":"Internal error","detail":""}]}

I think the body might be in the wrong format?!

Code:

    local requestBody = '{"type: 'Start', attributes: { duration: 24 // minutes}'

Any ideas how to improve?

Many thanks for your help!

Best Regards
