Adjust the Internal Filter
The Glow uses a pulse meter to track energy usage. In some situations, electrical noise or reflections near the meter's LED can cause false pulse detections, also known as ghost pulses. These show up as unrealistic power spikes (e.g. 1000 kW) in Home Assistant.
The internal filter defines the minimum duration (in microseconds) a signal must be active before it is counted as a valid pulse. Increasing this value filters out short noise pulses, reducing ghost detections.
The Glow defaults to 1000 µs (1 ms). If you are experiencing ghost detections, try increasing this value gradually.
Setting the internal filter too high can cause real pulses to be missed, especially at high power consumption or with meters that have a high imp/kWh rate. A value up to 10000 µs (10 ms) is a good starting point for most residential setups.
You can adjust the value in 2 ways:
Option 1: Via the web interface
Open the web server by going to the IP address of your Home Assistant Glow, where you will find the line Internal Filter in the table, and you can adjust it on the right.
Option 2: In Home Assistant
- Go to the device overview page of the Home Assistant Glow, via Settings > Devices & Services > ESPHome.
- Adjust the value for the entity Internal Filter under the configuration section.
Since the internal filter is now controlled at runtime via the Internal Filter entity, overriding internal_filter directly on the pulse meter sensor in your YAML configuration will no longer work. The entity value always takes precedence after boot. Use one of the two options above instead.
