Version 1.1.0 pre-release is out.

[TypQxQ]

Lots of updates so I bump up a subversion to v.1.1.0

Accumulated Sensors Now Static and Reliable

In previous versions, “accumulated” sensors were calculated locally in Home Assistant. Starting in v1.1.0, some of these sensors pull their lifetime totals directly from Sigenergy via Modbus 2.7. That means:

• You’ll see true lifetime totals, even if Home Assistant is offline or restarting.
• On upgrade, the integration will poll the new Sigenergy totals, ensuring seamless continuity.
• Name of the affected sensors changed to "Total" instead of "Accumulated" to indicate where the data comes from.
• The device id remains unchanged for historical data to still function but there will be a massive jump in the totals at the time of install.
• See list below for affected sensors.

Faster updates and only one update interval

I deleted the different update intervalls and only saved the high update interval. If you have changed from default of 5 seconds, you might have to change it again under settings. Each update now reads all Modbus addresses in larger chunks and is thus much faster.

Updated DC Charger updates

The logic here has changed and is not fully tested as I still don't own a Sigenergy charger. If someone feels like sponsoring me with one, I'm sure I could get more functionallity.

Updated to Modbus 2.7

Many more sensors. Most are disabled by default as to not burden the Home Assistant History and log every litle change.

Added sensors:

• plant_total_generation_of_third_party_inverter
• plant_smart_load_XX_power ( where XX is 1 - 24 )
• plant_smart_load_XX_total_consumption ( where XX is 1 - 24 )
• plant_total_discharged_energy_of_the_evdc
• plant_total_charged_energy_of_the_evdc
• plant_total_generation_of_self_pv
• plant_total_charged_energy_of_the_evac
• plant_total_energy_output_of_oil_fueled_generator
• inverter_power_factor_adjustment_feedback
• inverter_reactive_power_qs_adjustment_feedback
• inverter_active_power_percentage_adjustment_feedback
• inverter_reactive_power_fixed_value_adjustment_feedback
• inverter_active_power_fixed_value_adjustment_feedback

Sensors have moved from calculated to static sensors.

• plant_accumulated_battery_charge_energy
• plant_accumulated_battery_discharge_energy
• plant_accumulated_consumed_energy
• plant_daily_consumed_energy
• plant_accumulated_pv_energy
• plant_accumulated_grid_export_energy
• plant_accumulated_grid_import_energy
• inverter_accumulated_pv_energy
• inverter_daily_pv_energy

Configurable values added:

• plant_discharge_cut_off_soc
• plant_charge_cut_off_soc
• plant_backup_soc

It is now released as a pre-release and I would love to get some feedback.
It's installable trough HACS if you force the new version.

I installed it to play with the max charge SOC.

After a couple of hours of using it, my HA is now stuck "loading data", even after a hard reboot of the pi.

Might be unrelated to 1.1.0

Might be unrelated to 1.1.0

the issue is likely unrelated. It's one 1 device (MacBook) that suddenly is stuck in a "loading data" loop. Various browsers and native app all affected. Other devices working as usual.

Worked out my issue of why my pymodbus kept reverting to 3.0.0 it was in my Grant Aerona3 integration, I have now updated that to pymodbus >=3.8.3 so no more conflicts hopefully.

Battery Warranty Life Spent.
What is this value as I have added it and it reports 100% but before this new version it was saying I had used 9%.
It's annoying all the values have changed and I have to amend everything but it works none the less.

[TypQxQ]

I believe you are talking about something completely different.

"Battery Warranty Life Spent" is something not available in this integration but comes from the old yaml based one.
It is not supported to have both installed.
Migrating from the old yaml file to the HACS integration, you have to delete the old one first and as you say, naming conventions have changed with the new feature set.

Upgrading from v.1.0 to v.1.1.0 should retain all history and field names.

I applied this earlier today and it immediately screwed up the 'accumulated' sensors.
Some of them immediately doubled and the plant_accumulated_pv_energy went from ~950kWh to 5,000+ kWh.

Uninstalled and reinstalled with the prior version and didn't fix anything up. Deleted from HACS and reinstalled and no luck either. Ended up having to roll back to the backup from when I updated to HA 2025.8.0 30 hours before.

This is normal and expected as it now changes accumulated (counted in HA) to Total, from Sigenergy. This is the actual lifetime production total and will much better add up. Even when HA is down.

Sorry to hijack this thread, but this is the only place my search for "migrate" came up with anything for going from the old yaml setup to the new integration. Is there any guide for this? I quite like the old dashboard and I'd like to keep it as much as I can but obviously all the entities have changed name.

Hi Andrei, I've updated my setup to v1.1.0 and the EVDC switch and sensors no longer appear to work at all. I've raised #141 describing the behaviours.

[Roving-Ronin]

Hi Andre @TypQxQ

Just applied v1.1.0 and see that (most) of the Accumulated sensors display name have changed to Total, but notice the entities remain as showing Accumulated.
i.e. Display = Sigen Inverter / Total PV Energy. Entity ID = sigen_inverter_accumulated_pv_energy

I assume that on new (re)installations, these entities would in future default to: sigen_inverter_total_pv_energy ?
Just wondering as if so, thinking for long term compatability it might be worth going through and manually updating them?

Also you mention the Inverter PV# Accumulated Energy sensors have moved to static sensors, I assume this means they should be Total Energy instead? If so, I notice that mine as still showing the display name of 'Sigen Inverter PV# Accumulated Energy' and the same for the entity. Should these update to: Display = 'Sigen Inverter PV# Total Energy' and Entity ID = 'sigen_inverter_pv#_total_energy' ?

Thanks !

Looks like v.1.1.3 has been tagged as v.1.1.13, so doesn't appear after v.1.1.2 in the download list.
