Power-Meter: Timeout

[JanLue4]

Hi!
First of all thank you for the fantastic Project!

I have installed the Solar-Power-Meter yesterday and it works fine.

My Wifi Tasmota Power Sensor is not sending a new value within 5 Seconds. So the Meter sends a "meter fault".
I have changed the "power_sensor_inactivity_timeout:" to 60s and it looks good for the first minutes.
What happens if I delete the entry "power_sensor_inactivity_timeout:"? Does the Meter still work?

Best Regards
Jan

If you delete the power_sensor_inactivity_timeout parameter the default value of 5 seconds will be used again:

IMO you should multiply the average update interval of your powermeter by 5 and use this value as inactivity timeout. This avoids too much overshooting / exporting power to the grid if the powermeter is unable to provide valid power demands.

Thank you for the quick answer.
I tried so get a value every 5 seconds, but it does not work. I will order a Shelly Pro 3 EM to get valid values.

How do you read out your smart meter at the moment? What's the update interval of your smart meter in general?

[JanLue4]

I used MQTT. The Tasmota Script of the Smart Meter is set at 1s but if I set 5s it doesn't change.

Does the Tasmota Script polls the smartmeter or it's a passive read out using an infrared receiver?

[JanLue4]

I am using an infrared Receiver, but in the script I can change the update time (if I have understand it correctly)

I am Using this script: https://tasmota.github.io/docs/Smart-Meter-Interface/#efr-sgm-c2c4-sml

It looks like your smart meter does publish a measurement per second.

You could try to use a ESPHome based approach to improve the performance / throughput:

Thank you. I am an absolutely beginner with ESP Boards, but I will try it.
