Thanks. Just for reference, it took me multiple searches to figure out how to turn on log_to_file in (edited as per posts below):
…/hassio/addon/core_zwave_js/config
For the good news…
I looked at the log at /config/zwave_js/logs last night, the one you advised me not to do, and saw events like this for kWh and power (power shown):
2024-11-23T15:42:56.880Z SERIAL « 0x010e0004001508310504640006c93a49 (16 bytes)
2024-11-23T15:42:56.883Z SERIAL » [ACK] (0x06)
2024-11-23T15:42:56.886Z CNTRLR [Node 021] [Multilevel Sensor] Power: metadata updated [Endpoint 0]
2024-11-23T15:42:56.888Z CNTRLR [Node 021] [~] [Multilevel Sensor] Power: 443.96 => 444.73 [Endpoint 0]
2024-11-23T15:42:56.890Z DRIVER « [Node 021] [REQ] [ApplicationCommand]
└─[MultilevelSensorCCReport]
sensor type: Power
scale: Watt
value: 444.73
The default entities were still not updating from the original inclusion. I looked for an entity called “MultilevelSensorCCReport” to put on my dashboard, but could not find one. There were kWh and other power updates too in the log that I didn’t need, so I went into the config.
I left Parameter 111 (Report Interval (Group 1)) at 60 sec.
I turned off all switches except Parameter 101, Bitmask 2 (Automatic Report: Group 1 - MultiSensor Wattage (Whole HEM)), since the log mentioned “MultiSensor.”
The kWh log entries stopped and the power continued. I think–but do not clearly remember if I checked–that the default entities shown remained unchanged last night.
This morning, I had the idea that something might have been added to the Overview dashboard, since something was reporting. Nothing had been added, but now the default entities were updating every minute!
So the one thing I wanted is working as desired. I suspect the same would be true for usage in kWh. I don’t know whether the Parameter 101, Bitmask 2 switch being on has anything to do with it, but at this point I’m afraid to experiment and lose it. I’m not sure whether Parameter 1 should be 120 or 240 v; nor whether I should be using Power, Power (1), or Power (2), but I can use a known load to figure that out.
TL;DR–turn on the switches for desired MultiSensor parameters and wait.
Just posting this for someone else; not sure if this post should be checked as the solution. Thanks for all your help.
