Home Assistant SunPower Integration using the local installer ethernet interface.
Original Integration is https://github.com/krbaker/hass-sunpower
- If this is a fork, please add what's different here and fix up the badges below
This integration uses endpoints designed for the provisioning of the PVS system. They were not intended to be called over and over for days/months/years on end. I have seen PVS systems eventually failing to push data to Sunpower's cloud systems even though everything else (this integration included) were working. This happened to my system and I did a bunch of gymnastics some of the errors suggested it might have been due to a partition filling on the PVS. I would certainly use caution with short polling rates.
YMMV, any damage to your system is your responsibility (see also: LICENSE)
Component to integrate with sunpower PVS 5/6 monitors
Notes:
- For PVS < 5 you can try jcronq's fork https://github.com/jcronq/hass-sunpower
- The Original ESS fork by CanisUrsa is here. This work has been integrated with some changes. https://github.com/CanisUrsa/hass-sunpower
This component will set up the following platforms.

Most data available from the PVS system including per-panel data. |
- Click install.
- Install HACS
- Add this Repo to HACS by going to the 3 dots on the right ...-> Custom repositories -> Repository: krbaker/hass-sunpower Category: integration
- Install this integration in HACS
- Restart Home Assistant
- In the Home Assistant UI go to "Configuration" -> "Integrations" click "+" and search for "Sunpower".
- The main configuration is IP/Hostname. If setup with a NAT as described below the IP will be 172.27.153.1. Note the network setup is for most people the challenging setup of this integration.
- Requires that the management LAN interface is plugged in, your installer uses this for setup but doesn't plug it into your lan
- This network interface has a DHCP server running on it. If you plug it straight into your home network it will make probably other systems stop working as they will DHCP to the wrong address. The PVS takes a very long time to return data, I've found 120s is really the lowest safe rate. ESS I'm less sure about though I've seen it as low as 10s in other places (I have seen home assistant grind to a hault with too many state change entries)
When selected during installation, entities added for each device will have the device descriptor added onto the front of their name. The device descriptor is a combination of device type (e.g., Inverter) and serial number. This guarantees unique entity IDs and names at the expense of making said names very long.
When selected during installation, entities added for each device will have the "product" descriptor added onto the front of their name. This adds 'sunpower' 'sunvault' and 'pvs' to entities making them even more distinct but very long.
This will now auto-detect and the option to enable/disable has been removed (This addition thanks to @CanisUrsa)
This sets how fast the integration will try to get updated solar info from the PVS. The lowest "safe" rate looks like about 120 seconds. I am concerned some PVSs may fail to work properly over time and I'm guessing it might be request or error logging filling their memory. I am running with 300 seconds right now as I went through a heck of a time with a PVS that began to fail pushing to Sunpower's cloud.
Should evenly divide into Solar data update interval or be an even multiple of it (this is due to the currently silly way polling is handled through one timer). The original author of the ESS addon @CanisUrsa had it as low as 20 seconds (see warning above)
This integration requires connectivity to the management interface used for installing the system. The PVS systems have a second lan interface in the box. DO NOT PLUG THIS INTO YOUR LAN!!! it is running its own DHCP server which will cause all sorts of IP addressing issues. I run a Linux router with a spare ethernet port and route to the sunpower interface and allow my home assistant system to connect directly to the PVS. Also note that the command used to dump data 'device list' is very slow and sometimes times out. I've built in some retry logic so setup passes pretty reliably. Sometimes you may see data go blank if the fetch times out.
A detailed setup using a Raspberry Pi which fits into the PVS is available here.
Depending on the version of PVS you may not see all of these devices/attributes. I'm guessing on a number of these attributes based on what I've observed. Updates welcome!
This is the integrated computer that monitors your panels. Currently this supports the PVS 5 and PVS 6. The serial number is used for the device ID to avoid collisions.

This is the power meter built into the PVS. The serial number is used for the device ID to avoid collisions. All systems I have seen have two meters one ends in 'p' for production (from panels) and 'c' for consumption (use by household).

This integration should support the Energy dashboard for Home Assistant. Once you install the integration and configure it allow it to run for a few hours so that the statistics entries are generated. Then go to the energy dashboard configuration and add the measurements you want. Some people use the main consumption and production meters, others use each panel.
The energy storage system data doesn't record total kWh and instead only provides voltage / current of the individual battery management systems. The instanteous power is calculated per battery and an abstract battery called "SunVault" is generated to cover systems with more than one BMS. For the SunVault device an integration helper is required to integrate the instanteous power calculated by this integration and turn it into kWh. This can be done through Settings -> Devices and Integration -> Helpers -> Create Helper -> Integration - Riemann sum integral sensor. An integration sensor will need to be generated for both the SunVault Power Input and SunVault Power Output.
If you file a bug one of the most useful things to include is the output of
Run the debugging command and look for the METER entries.
curl http://172.27.153.1/cgi-bin/dl_cgi?Command=DeviceList If one is missing reboot the PVS
Check your Sunpower app. If its not there this integaration will not solve it.
- Your install may not have installed the current clamps needed. Sometimes the installer is being cheap, sometimes you just don't have the space in your panel.
- Its possible your PVS just needs a reboot (see missing solar production entry)
- If your consumption is just wrong (the most common failure is seeing the solar production count as consumption) then the PVS is configured wrong Sunpower Training is what they should follow to resolve this.
