List all power meter components (PM/PM1) on a device.
PM components are power meters typically found on multi-channel devices
(Shelly Pro 4PM, etc.). PM1 components are single-channel power meters
found on devices like Shelly Plus 1PM.
Use ‘shelly power status’ with a component ID to get real-time readings.
Output is formatted as a table by default. Use -o json or -o yaml for
structured output suitable for scripting.
# List power meter components on a device
shelly power list living-room
# Output as JSON for scripting
shelly power list living-room -o json
# Get count of power meter components
shelly power list living-room -o json | jq length
# Get IDs of PM1 components only
shelly power list living-room -o json | jq -r '.[] | select(.type == "PM1") | .id'
# Check all devices for power meters
shelly device list -o json | jq -r '.[].name' | while read dev; do
count=$(shelly power list "$dev" -o json 2>/dev/null | jq length)
[ "$count" -gt 0 ] && echo "$dev: $count power meters"
done
# Short form
shelly power ls living-room
