Very funny... Discovery info: {'topic': 'hasp/discovery', 'payload': '{"node":"plate_4","mdl":"Lanbon L8","mf":"openHASP","hwid":"xxxxxxxxxxxxx","pages":12,"sw":"0.6.2","input":{},"power":[],"light":[12,14,27],"dim":[]}', 'qos': 0, 'retain': 0, 'subscribed_topic': 'hasp/discovery', 'timestamp': datetime.datetime(2021, 8, 5, 12, 48, 30, 819614, tzinfo=datetime.timezone.utc)}

https://jsonlint.com/ , https://jsonformatter.org/ say this is not valid json.

[fvanroie]

openHASP sends this discovery payload:

{
    "node": "plate_4",
    "mdl": "Lanbon L8",
    "mf": "openHASP",
    "hwid": "xxxxxxxxxxxxx",
    "pages": 12,
    "sw": "0.6.2",
    "input": {},
    "power": [],
    "light": [12, 14, 27],
    "dim": []
}

That is a valid json object. HA makes it into a larger JSON object, adding topic, payload and timestamp keys that is not valid anymore...

[nagyrobi]

Yes, single quotes around '{}' invalidates it.
