Template variable error: 'dict object' has no attribute 'result' when rendering...

[roofburner]

I'm getting the below kind of errors in my home-assistant.log

ERROR (MainThread) [homeassistant.helpers.template] Template variable error: 'dict object' has no attribute 'result' when rendering '{%if value_json.result.sys.available_updates.stable is defined%}ON{%else%}OFF{%endif%}'

Show me please your device script (Scripts section in the device web panel) and the payloads that the device sends to the MQTT broker.

TCPDump (PCAP - shelly.zip) attached. Hope this helps. Or can you explain me how to get hands on the payload? shelly.zip

This is what the script looks like:

Script name: shellies_discovery_gen2_script_20240216

Script

let topic_prefix = null;
let installed_version = null;

Shelly.call("MQTT.GetConfig", {}, function (config) {
    topic_prefix = config.topic_prefix;
});

function SendDeviceStatus() {
    let _device_info = Shelly.getDeviceInfo();
    installed_version = _device_info.ver;
    Shelly.call("Shelly.GetStatus", {}, function (status) {
        status.sys.installed_version = installed_version;
        MQTT.publish(topic_prefix + "/status/rpc", JSON.stringify(status));
    });
};

MQTT.setConnectHandler(SendDeviceStatus);
let UpdateTimer = Timer.set(1800000, true, SendDeviceStatus);

Or can you explain me how to get hands on the payload?

I meant a screenshot from MQTT Explorer (launch MQTT Explorer, wait 10 minutes and take a screenshot).

[roofburner]

OK. I will provide you a screenshot asap.

[bieniu]

I checked the script code and it does not contain JSON paths like those in your errors:

value_json.result.sys.available_updates.stable
value_json.result.mqtt.connected

The script uses those paths:

value_json.sys.available_updates.stable
value_json.mqtt.connected

So the source of the errors is not Shellies Discovery Gen2.

[bieniu]

You can find the cause of errors by searching in MQTT Explorer if MQTT Discovery was used to configure the device
