APsystems
apsystems
The APsystems integration allows you to read the data from your APsystems EZ1 microinverter. It also allows you to set the output limit to anything above 30 watts.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

| APsystems EZ1-M | Works Local | Whole EZ1 series supported since 2024.8Saved copyProposed change As there are more inverters of the ez1 series by apsystems with each having another max output, this PR queries the inverter on first setup and saves the max output which is then reused for the number entity.

| APsystems EZ1-LV and EZ1D | Partly works Local | Works but shown as EZ1-M; model fix PR openSaved copyProposed change The `apsystems` integration hardcodes `model="EZ1-M"` for every device, which is wrong for the other EZ1-series models served by the same local API (e.g. EZ1-LV, EZ1D). Derive the model from the first token of the device-reported version string (`devVer`), keeping `EZ1-M` as the fallback when the string carries only a version number. Adds a regression test. Real-world example: an EZ1-LV reports `devVer = "EZ1-LV 1.1.5"`; before this change HA shows `model: EZ1-M`, after it shows `model: EZ1-LV`. ## Type of change - [ ] Dependency upgrade - [x] Bugfix (non-breaking change which … Excerpt saved from GitHub on 2026-10-23. | PR #186562 · 2026-10 | |
