Hi, Im looking to see if anyone has successfully managed to integrate the Sigenergy Inverter and Batteries into Home Assistant with the system connected to the Amber Electric VPP and can still have full control in Home Assistant of the Sigenergy system. I have heard that the systems may fight against each other or Amber will have control over HA.
I have set up the Sigenergy Integration here, which is excellent.
You can also install the Amber Electric Integration which will give you up to date energy prices which should allow you to control the export of your energy.
But im not sure if you get control over battery levels, exporting and importing electricity based on electricty price.
to answer my own question. Yes, it is possible. Use the Amber Integration with the above SigEnergy Integration. You will also need the EMHass Integration and the Solcast Integration. I also followed Brendanās pages on how to modify the energy management with his script and automations. I modified these to suit my requirements. Here is the link to Brendanās pages.

Its working great now with more control when required
Iāve started doing this, just havent enabled the battery automation section yet. Just curious, what happened when you turned on the āRemote EMS (Controlled by Home Assistant)ā switch? Are you still able to turn on SmartShift in the Amber app? Or do you need to contact them like mentioned in the process? Thanks
Itās my understanding that you can go back to smart shift, but you need to contact amber to do it. You are pretty much on your own once you do it for controlling your system. Although I havent tried turning switch on to see what happens
I can still monitor usage and costs/profit through the amber app
Thanks. Yeah I actually turned off smartshift off in the amber app for the last few days. I like the idea of just using in self consumption mode and only really export if/when its a solid price. A few times amber tried charging the battery at full speed when I couldve easily gotten through the night without the top-up. I think the main thing is we have access to the wholesale prices, then we can do what we want really.
Is anyone else on flexible exports from the network itself - and any idea if the current limit is something thatās accessible?
So far I donāt appear to have been limited since installation of the battery a cupla weeks ago, so itās a bit hard to tell anyway.
I have also played around with some other helpers and automations along with the script and EMhass in home assistant to further negate the need to touch the system, although not quite fully there. I use an overnight battery minimum that cuts the EMS off when it goes below this level. I have it set so that if there are price spikes though it will switch back on again. Through the day I have export price minimum set which is adjustable. The same goes if the the ems is off and there is a price spike it will switch back on again. If the battery gets to 100% it will export anyway, but never below 2 cents. Without this I have seen the script export at zero. I aināt flogging my inverter to only sell at 1c or zero. My aim next is to set my Battery soc level and export price helpers automatically based on upcoming solar estimates from solcast. I use a night window toggle that sets each day based on sunset and sunrise with the sunrise switch over adjustable ether side of sunrise for EMS switch on. The way it works is, the battery soc level is used through the night and the export price through the day to determine when to sell. Works reasonably well
Nice. Yeah I plan to one day have HA fully controlling it so I dont have to really touch it. Not sure if thats really possible but its early days with the home battery and theres so much potential with HA.
Has anyone managed to use home assistant to configure āsolar producing power limitā that is in the app? Effectively running your own curtailment. I see most of the config options in home assistant, but the closest I can see for this is the āPV Max Power Limitā, though it doesnt appear to change anything in the app. Thanks
I activated Remote EMS by mistake and wasnāt able to reconnect to Amber VPP. From what I can see, you need to go through Amber support at the moment to reconnect. So here I am trying to replicate Amber Smart Shift on Home Assistant.
Yes I did the same, but held off for a while as it sounded like it might be difficult to re-enable. I was basically using the battery in self consumption and would manually discharge on the odd day as I didnt fully trust smartshift. When I turned on the remote EMS switch in home assistant, it seems to forcibly remove the battery from Ambers VPP operation mode and lets me choose any mode in the mysigen app. Iām wondering if something flags on the amber side with my battery if its no long in the VPP mode but nothing yet.
Yes once you go to EMS mode you need to contact Amber Electric to go back. I use a modified version of this to control my Sigenergy with home assistant. It relies on the following components to make it work. Running EMHASS | Sigenergy with Home Assistant and EMHASS

Some other modifcations to Brendans Scripts
Hi all. Having a head scratcher and I am not sure what to do to fix it. I keep getting the following error when I manually run the Generate EMHASS Energy Plan (MPC) script:
āFailed to perform the action script/generate_emhass_energy_plan_mpc. TypeError: āNoneTypeā object is not iterableā
My sensor entity names are all correct as per the guide as best I can tell. When I run a trace on the script it crashes out at the āCalculate payloadā step and throws the above error.
I am guessing its got something to do with a sensor not being enabled, but as far as I can tell they all are.
I get a similar error after I restart home assistant but usually ignore it. Iām not exactly sure if it is the same as yours. Go into developer tools and confirm the MPC entities are there. If they are not then that is a problem
