Hello, I have a Shelly Plug S (Gen3) here for testing purposes and have first configured an MQQT agent in Openremote and then added my plug asset. So far, this is working, i.e., the socket switches as desired. However, it is not yet running smoothly; I see errors in the OR log, and the toggle switch itself always displays “Send failed.” Here is a screenshot of my configuration:
That’s the json:
{
"id": "6zH57b5HATLJkRVsAO4PVP",
"writeValueConverter": {
"TRUE": "{\"id\":1,\"src\":\"openremote\",\"method\":\"Switch.Set\",\"params\":{\"id\":0,\"on\":true}}",
"FALSE": "{\"id\":1,\"src\":\"openremote\",\"method\":\"Switch.Set\",\"params\":{\"id\":0,\"on\":false}}"
},
"writeValue": "",
"messageMatchFilters": [
{
"type": "jsonPath",
"path": "$.params[\"switch:0\"].output",
"returnFirst": false,
"returnLast": true
}
],
"updateOnWrite": false,
"subscriptionTopic": "sp-wz-01/events/rpc",
"publishTopic": "sp-wz-01/rpc",
"type": "MQTTAgentLink"
}
I see the following messages in the Openremote log:
| 16.12.2025 22:38:00 | WARN | PROTOCOL | ProtocolUtil | Cannot send linked attribute update: assetId=6vb1iI2WBAl7DyqeLeMvnq, attribute=onOff | |
|---|---|---|---|---|---|

| 16.12.2025 22:38:00 | WARN | MODEL_AND_VALUES | ValueUtil | Failed to parse JSON |
Can anyone give me a hint as to what I need to change? Thanks in advance!
Regards,
Peter
