I am still breaking my mind on it.
I redo all the steps from the start.
Deleted Shelly for Hass
Reinstalled the script trough HACS
this is my configuration.yaml
python_script:
logger:
default: warning
logs:
homeassistant.components.python_script: debug
homeassistant.components.automation: info
then added this on automations.yaml
- id: 'shellies_announce'
alias: 'Shellies Announce'
trigger:
platform: homeassistant
event: start
action:
service: mqtt.publish
data:
topic: shellies/command
payload: announce
- id: 'shellies_discovery'
alias: 'Shellies Discovery'
mode: queued
max: 999
trigger:
- platform: homeassistant
event: start
- platform: time_pattern
hours: "/1"
action:
service: python_script.shellies_discovery
data_template:
id: '{{ trigger.payload_json.id }}'
mac: '{{ trigger.payload_json.mac }}'
fw_ver: '{{ trigger.payload_json.fw_ver }}'
In the shelly
enabled MQTT with right parameter clean session and retain checked MaxQoS 0
custom Mqtt prefix unflagged ( even if I should be able to change it right? )
flagged device discoverable
restarted HA
then in integration - MQTT mosquito broker - I can’t find any new discovered mqtt device but if I open mosquito log I can read that the shelly is correctly connected.
I manually launched Shellies Announce with the same results
If I run announce automation I can see this message in MQTT explorer
I deleted the HA log and restarted this is the new fresh log

If I search for the shelly in entity I can only find it as device tracker
I really don’t understand what I am missing
