Getting a "more" dynamic display?

Configuration
1

I have a power meter (SDM230), giving me 15 entities. One of these (Active Power) I have displayed as a Gauge in a Dashboard.
Disappointingly, although I know (by watching meter display) that in reality, the power is “dancing around” in response to cooking demands and solar excess, the Gauge display reports that it has not changed/updated for long periods of time?

I note multiple postings with the advice that using “force_update” is very (very) bad! So not tried that yet. If “force_update” were to produce the effect I’m looking for, would it be so bad if it were only for display and not logged to the Home Assistant database?

Should I be able to achieve “near real-time” updates from my SDM230 sensor to the Dashboard Graph display?

Regards, Martin

Try watching the state in Developer Tools → States. Does that change?

Can you show the configuration for this sensor?

Hi Tom,
Watched for 5min. No movement…

This (I think) are the relevent sections of my esphome yaml:

That should be reporting all the modbus sensor values every ten seconds.

Have a look at the esphome device serial log.

Do you see it sending data?

So, as I read it, the UART/Modbus write/read traffic is every 10 seconds. But although some the values returned are differing from the previous read, the only sensor that was sent to Home Assistant during this sample run was for “Export Active Energy” at [18:49:44].

Regards, M.
PS - Although, I think I have 15 entities defined in the yaml, only 4 are listed in the log pre-amble. Is this normal?

It does not look like that ESP component is working as expected.

Okay Tom, thanks for looking.

I have done a hardware replacement - with no change.
Any suggestion on how I can raise a question with the sdm_meter platform maintainer?
Had a hunt around, but the nearest I can find says “Do not post here”?
Regards, M.
