MQTT discovery of custom entity doesn't consider type of data

[SSSlee]

The datatype of a customized entity isn't mentioned in the belonging MQTT Discovery:

Corresponding MQTT discovery:

{
"stat_t": "ems-esp/custom_data",
"val_tpl": "{{value_json['RFM200'] if value_json['RFM200'] is defined}}",
"obj_id": "custom_RFM200",
"uniq_id": "custom_RFM200",
"name": "RFM200",
"dev": {
"name": "ems-esp Custom",
"mf": "EMS-ESP",
"mdl": "Custom",
"via_device": "ems-esp",
"ids": [
"ems-esp-custom"
]
}
"avty": [
{
"t": "ems-esp/status",
"val_tpl": "{{'online' if value == 'online' else 'offline'}}"
},
{
"t": "ems-esp/custom_data",
"val_tpl": "{{'online' if value_json['RFM200'] is defined else 'offline'}}"
}
],
"avty_mode": "all"
}`

Discovery for a temperature datatype (in comparsion):

{
"uniq_id": "thermostat_dampedoutdoortemp",
"obj_id": "thermostat_dampedoutdoortemp",
"stat_t": "ems-esp/thermostat_data",
"name": "Damped outdoor temperature",
"unit_of_meas": "°C",
"val_tpl": "{{value_json.dampedoutdoortemp if value_json.dampedoutdoortemp is defined else 0}}",
"stat_cla": "measurement",
"dev_cla": "temperature",
"dev": {
"ids": [
"ems-esp-thermostat"
],
"name": "ems-esp Thermostat"
},
"avty": [
{
"t": "ems-esp/status",
"val_tpl": "{{'online' if value == 'online' else 'offline'}}"
},
{
"t": "ems-esp/thermostat_data",
"val_tpl": "{{'online' if value_json.dampedoutdoortemp is defined else 'offline'}}"
}
],
"avty_mode": "all"
}

looks like we need to add both "unit_of_meas" and the "stat_cla"

@SSSlee if you add those two manually to the discovery topic (using MQTT Explorer) does it fix your issue? Worth trying before I change the EMS-ESP code and unintentionally break something else.

fixed in dev13

Hi,
Noticed in v. 3.6.5 MQTT discovery of external temperature sensor for HA is missing "stat_cla" attribute. So this entity is not recored, nor cannot be added to any statistics card.

I added the attribute manually via MQTT Explorer and HA starts recording it.

thanks, created new bug for this
