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:

123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081

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 -- Beispielaufrufe getAccessToken() getMowerIds()

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

Code:

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

Code:

12345678910111213141516

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:

1

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:

1

    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:

12345678

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

Hi @all,

during testing I found an issue with this string compare:

Code:

123

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.

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.
