First version of my LazySpa2MQTT script which I use together with openHAB.

This is just a basic script, feeding values from the API into MQTT subjects. Plan is to extend it to also be able to turn on/off pump and adjust temp setpoint.. Also my very first python script :-) (so dont kill me..)

Place the script and config in /etc/openhab/scripts (modify the script for config location if different).

Run the script ie. every 30min in a cron. */15 * * * * python3 /etc/openhab/scripts/layzspa.py >/dev/null 2>&1

The DID and API_TOKEN is obtained by i.e. using postman (https://www.postman.com/) and using the following settings; POST https://mobileapi.lay-z-spa.co.uk/v1/auth/login body; raw with the text: email=asdf%40gmail.com&password=asdf

The API will return a JSON with the following format; { "data": { "id": 1111, "firstname": "asdf", "lastname": "asdf", "email": "asdf@gmail.com", "address_line1": "null", "town": "", "county": null, "country": "", "postcode": "", "optin": 1, "enabled": true, "gizwits_email": null, "gizwits_key": null, "gizwits_uid": "asdfasdfasdfasdf", "gizwits_expires_at": "2020-11-05 06:48:58", "gizwits_token": "asdfasdfadsf", "created_at": "2020-04-09 23:11:21", "updated_at": "2020-05-09 18:22:58", "last_login_at": null, "api_token-bkp": "", "api_token-bkp2": "", "api_token": "asdfasdfasdfasdfasdf", "full_name": "asdf asdf", "anonymous_id": "asdfasdfasdf" }, "devices": [ { "id": 2222, "did": "asdfasdfasdfasdf", "mac": "D8AAAA261FA", "product_key": "asdfasdfasdf", "uid": "asdfasdfasdf", "user_token": "asdfasdfasdfasdf", "app_uid": "2222", "created_at": "2020-05-16 22:22:11", "updated_at": "2020-05-16 22:22:11", "device_name": "My Lay-Z-Spa", "pump_type": null } ], "message": "Authorization Successful!" }

Grab the api_token, and did from devices and use it in the config.
