Thanks @Bieniu, changing from hass to homeassistant for the discovery prefix fixed the problem. Don’t know how I missed it, but you might change it in your example automation to match the default.
I will check with Shelly support as to why the MAC doesn’t match the reported MAC
Hello @Bieniu and thanks for this beautiful script !
I’m trying to use it with my Shelly HT , and i feel like i’m not far from succeed but I don’t know what i’m missing.
I’m using embeded MQTT on home assistant on docker, i’m receiving well MQTT messages from my shelly , but no entity are created, do you know what I should watch next ?
thanks in advance
Best regards,
Do you use correct automation to run the script? In your topics thera aren’t MAC addresses and firmware versions.
- id: 'shellies_discovery'
alias: 'Shellies Discovery'
trigger:
- platform: mqtt
topic: shellies/announce
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 }}'
Hello, thanks for your answer !
I have put this in the automations.yaml file
You have to write me full announce topic that your Shelly send to MQTT broker.
Thanks again for your answer, sorry i’m a bit new to MQTT.
From what I understand I need to subscribe with a MQTT client to directly read the shellies topic, right ?
my MQTT server isn’t exposed from outside so I can’t use an MQTT client right now, i’ll try tonight at home.
The only thing I can provide right now is the HA logs, where just before the “Transmitting messages” the MQTT component is logging the received message, which seems not that much verbose :
Regards,
Very strange. This isn’t correct payload for Shelly announce topic. This is example of correct payload:
{"id":"shellyht-XXXXXX","mac":"XXXXXXXXXXXX","ip":"192.168.1.56","new_fw":false, "fw_ver":"20190402-134544/v1.4.9@9be72c7e"}
Without that my script doesn’t work.
Maybe factory reset helps?
Yeah, mine feels a bit truncated 
I’ll try to maybe update my firmware and/or factory reset as suggested .
I’ll tell you result tonight !
Thanks for your advices !
So, I have updated the Shelly HT firmware, it seems better , but still no entities showing
There is one error showing 10 sec after your python script is processed , don’t know if it’s related :
Regards,
Now it looks good. Are you sure that there isn’t Shelly H&T in Settings -> Integrations -> MQTT in HA?
Please use text logs in post.
New version: 0.4.2
Changelog:
Are there any MQTT or Discovery errors in log associated? I can’t help if I don’t know where the problem is. You use the built-in MQTT broker. Have you considered installing the Mosquitto? The built-in broker has issues and will soon be removed from HA.
Hello again,
I installed mosquitto and had the same behaviour
I finally got it working, it was much more simple than I thought, I think this is basic for MQTT users, but for begginers like me it was not obvious. Maybe this should be written in your prerequierements :
Don’t use GUI MQTT configuration, configure MQTT in yaml file to put the discovery variable to true :
mqtt:
broker: 192.168.xxx.xx
port: 1883
username: xxxxx
password: xxxxx
discovery: true
discovery_prefix: homeassistant
This is what was missing for me for this to work :
discovery: true
discovery_prefix: homeassistant
Now I have another issue with the auto discover script. Even with the retain label on, sensors are getting unavailable in HA. I tried to create the sensor manually in the configuration.yaml and I don’t have this issue (left sensors auto discovered with your script, right manual with configuration.yaml) :
Here is my yaml :
platform: mqtt
name: "Humiditée Chambre"
state_topic: "shellies/shellyht-58FA2E/sensor/humidity"
unit_of_measurement: '%'
expire_after: 86400
force_update: true
json_attributes_topic: "shellies/shellyht-58FA2E/sensor/humidity"
Regards,
Do I understand correctly that the graph for the sensor is drawn but the state is unvailable? ShellyH&T connects to the network only from time to time and that is why most of the time is unavailable.
New version: 0.4.3

yes correct, Shelly HT comes only online every 4 or 5 hours or when the temperature exceeds the preset value.
