Error converting sValue/sUsage
NaN stands for Not a Number. So obviously you have received in Domoticz a wrong value.In the dashboard shows error NaN and no change to correct it.
I use MQTT as transmission method.Can you show us the data string, you send from Node-RED by MQTT or HTTP to Domoticz?
Code: Select all
msg1.payload = { "command": "udevice", "idx": 2577, "nvalue": 0, "svalue": total_power + ";" + total_energy };Code: Select all
msg.payload = { "command": "udevice", "idx": 636, "nvalue": 0, "svalue":msg.payload.toString()};
return msg;I think you should replace:Electric
The electric sensor will show the current usage of electricity in Watt and the cumulative usage in kWh. You can add digits after the decimal if needed.
{"command":"udevice", "idx":1234, "svalue":"us;cu"}
where us is usage in Watt and cu is cumulative usage in Wh (even though it is displayed in kWh)
Code: Select all
msg.payload = { "command": "udevice", "idx": 636, "nvalue": 0, "svalue":msg.payload.toString()};
return msg;Code: Select all
msg.payload = { "command": "udevice", "idx": 636, "nvalue": 0, "svalue":(msg.payload.toString() + ";0")};
return msg;This is exactly, what you were doing. So perhaps it will solve your issueThe problem seems to be in domoticz when receiving wrong or no values.
I got a solution with http but would like to do it with mqtt. I still don`t now how to get booth values together and sent it via mqtt. May you help me. That is correct, but it depends on the type of plug (generation 1 or generation 2), how to format the request.I took a look into shellies API and found that the plug is also sending energy
That is possible. I created something quick with an "Inject" node, (as I do not know the Generation of the Shelly yet)I got a solution with http but would like to do it with mqtt.

]I do not see it as a bug, but injecting wrong or no values in the Domoticz database is not a good idea.If crashing the dummy device by false values isn't a bug, could someone please move the tread.
I agree that the concept along that device in Domoticz is not failproof. But we have to deal with that...
