Husqvarna lawn robot mover API

[pioneersteffen]

Hi @all,

I want to connect my Husqvarna lawn robot to LM. 

There is an existing API which is documented here: https://developer.husqvarnagroup.cloud/a...onnect-api

I think I'm not fare away from the goal to start and stop the robot via LM but I struggling with the payload. 

After I registrated to Husqvarna development portal I created a script to find out the mover-id:

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 mowersEndpoint = 'https://api.amc.husqvarna.dev/v1/mowers'

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)
    }
log (code, status, headers, response_body)


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

-- Funktion zum Abrufen der Mower-IDs
function getMowerIds()
    local response_body = {}
    local _, code, _, _ = https.request{
        url = mowersEndpoint,
        method = 'GET',
        headers = {
            ['Authorization'] = 'Bearer ' .. accessToken,
            ['X-Api-Key'] = clientId,
            ['Authorization-Provider'] = 'husqvarna'
        },
        sink = ltn12.sink.table(response_body)
    }
log (code, status, headers, response_body)



    if code == 200 then
        local response = table.concat(response_body)
    log(response)
        local jsonResponse = json.decode(response)
       
        for _, mower in ipairs(jsonResponse.data) do
            local mowerId = mower.id
            -- Verarbeiten Sie die Mower-ID hier nach Bedarf
            print('Mower-ID:', mowerId)
           
        log(mowerId)
        end
    else
        -- Fehlerbehandlung
        print('Fehler beim Abrufen der Mower-IDs:', code)
    end
end

getAccessToken()
getMowerIds()

In the second step I tried to write a script to start and stop the robot:

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

-- Funktion zum Erhalten eines Zugriffstokens

    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

    local requestBody = '{"action":"start"}'

    local response_body = {}
    local _, code, _, _ = https.request{

            ['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

    end
end

    local requestBody = '{"name": "stop"}'

    local response_body = {}
    local _, code, _, _ = https.request{

        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

    else
        -- Fehlerbehandlung
        log('Fehler beim Stoppen des Automowers:', code)
    end
end

-- Beispielaufrufe

sendStartCommand()

If I call the script to start the robot I getting the following failures:

Code:

* arg: 1
  * number: 400
* arg: 2
  * nil

Automover  10.06.2023 15:12:33

  * string: Fehler beim Starten des Automowers:

Do you have any idea what I making wrong and need to change? 

Many thanks for your help!

[admin]

Have you tried doing what the error message suggests - set application/vnd.api+json content-type header? Also check request data format: https://developer.husqvarnagroup.cloud/a...api#readme
Use json.encode instead of raw JSON string or you will run into syntax errors.

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!

[Erwin van der Zwart]

Your payload is not a valid JSON, try : {"type": "Start", "attributes":[{"duration":"24 // minutes"}]}

You can test your payload at https://jsoneditoronline.org/

Are you sure the duration is like "24 // minutes" and not just the value 24 like  {"type": "Start", "attributes":[{"duration":24}]}?

[admin]

Try this:

Code:

local requestBody = json.encode({
  data = {
    type = 'Start',
    attributes = {
      duration = 24
    }
  }
})

Hi Erwin,
hi Admin,

many thanks for your help. This lead into a working solution.

For all guys who like to control (start/stop) the Husqvarna Automower via LM/W4K and a KNX button here is the description:

Hi @all,

during testing I found an issue with this string compare:

Code:

if status_mower == "STOPPED" or status_mover == "RESTRICTED" then
     grp.checkwrite('12/4/1', false)
end

Can you please help me and give me a hint how to improve it?

Many thanks!

Best Regards 
Steffen

[admin]

You have two different variables there - status_mower and status_mover. The docs state that there's a 10000 request limit per month. This means that you should retrieve the status not more often than once in 5 minutes.

Many thanks, it is working now. I corrected the script and the description in post #6.

Hi Steffen,
When i try to get the Mower ID i got nothing back as you can see below. Do you know if i need to take some extra steps or something?

* arg: 1
  * number: 200
* arg: 2
  * nil
* arg: 3
  * nil
* arg: 4
  * table:
  [1]
    * string: {"data":[]}

the access token part is working fine for me.
Best regards and thanks in advance,
Joep

I tried a lot so far but without luck. I hope someone can tell me what i do wrong as it seems to be a pairing issue but i have no idea how to solve it. The mower is registered from my account and i have created an application. I can also receive the Accesstoken so that part works.

["errors"]
* table:
[1]
* table:
["detail"]
* string: No pairing between the user and the mower product.
["title"]
* string: No mower pairing
["id"]
* string: 20c27a49-29be-4dd5-b055-b5bc8f5ef82f
["status"]
