Discovery payload is:
{
"name": "Dryer monitor 01",
"uniq_id": "dryermonitor01",
"avty_t": "basetopic/dryermonitor01/$system/status",
"pl_avail": "online",
"pl_not_avail": "offline",
"stat_t": "basetopic/dryermonitor01/state",
"stat_on": "on",
"stat_off": "off",
"opt": false,
"ic": "mdi:tumble-dryer"
}
However, Home Assistant doesn’t recognize the “online” state:

Can somebody spot the error I made?
I tried setting it manually using MQTT Explorer, didn’t help. I need an extra pair of eyes here…
Found another error when trying to make the “availability” to work. This time I used the MQTT Binary Sensor - Home Assistant (home-assistant.io)-availability setting.
I use the abbreviations to set the properties of the sensor. While the top level properties are expanded, the properties in the availability
-list are not, resulting in a parsing error.

Of course, I might be using it wrongly. Sending the discovery with full names works, but still doesn’t solve the original issue.
