Thanks, I have some specific circumstances that make this work for me, and don’t forget a 50kwh, battery on wheels, is considerably cheaper than the home battery. 
Do you know if there is a way to go off-grid from HA or even the App?
MySigen has an option to select going off-grid. Click on the Gateway from the Home screen and you will see a button to Go Off-Grid.
It may or may not operate as you hope, I think there are some scenarios where it may not reliably trigger going off grid.
I’m unaware of any such control available via Modbus / Home Assistant integration.
Thanks, I’ll have a play with that, next time I have some spare charge in the car, shame it can’t be automated but it’s a start.
Once again thanks for the pointers.
You can automate it with schedules in MySigen.
How did you do this? Did you put the sig on it’s on network?
Yeap, created a VLAN
Since I started to change the backup soc from HA, I just noticed that I lost this setting in the app.
Someone else? Is it possible to get back the backup soc level setting in the app?
I have it still, as well as Charge and Discharge cut-off SOCs.
Thanks. Then it might be of some other reason it is lost for me. Strange.
Edit: It seems that I have the Backup SOC level setting visable in MySigen app only when Peak Shaving is activeated. So it is not completely gone at least, and I guess it’s as it should be.
I’m looking a a sig energy system with the Bi directional EV charger and am looking for real user experiences: Does it work the way you want it to? Our EV is only occasionally used during the week so 98% of the time is on the drive and ideally its battery can be used to power the house in peak time and be charged from PV and lowest-cost grid rates as needed.
(Ideally it would be great if HA could look in my diary and see if I am planning on doing a long trip the next day and charge the EV accordingly.)
I find there is often a gap between what a system is capable of doing and how easy it is to actually use it fully, so very keen to hear how it works for you!
I recently gave my views on Sigenergy chargers in this video interview:
With HA all you can do for the DC charging module unit is switch the charger on and off. Any mode settings need to be done in the MySigen app. None of those are exposed via modbus as yet.
With the AC charge unit you can switch that on or off as well as set the charge current. Again any of the operating mode options need to be set with the MySigen app.
As for V2H, sure it’s possible but there are some practical limitations and personally I don’t think it’s useful for more than as a supplemental source of energy during long grid outages. Very few EV manufacturers will provide warranty coverage for non-standard use of the car’s battery.
Has anyone worked out a way to enable smart port manual mode from Home Assistant?
I currently have all my Sigenergy parameters controlled within HA except the smart port which is still managed by the Sigen App.
Though as its getting colder, I would like better control of our Hot water on the smart port. As I have hot water temp tracked in HA, it would be awesome if I could switch the smart port to heat the HWS if it has not met a temperature threshold while we are exporting surplus PV energy.

Does not the water heater’s own thermostat do that already?
Yes, the HWS thermostat will stop heating if its temperature is reached. Current control through the app is on time 11am-2pm. On days when this 3 hours is insufficient the heat to thermostat cut-off, I’d like to continue heating if we are exporting surplus solar energy.
I have entities for HWS temperature, so would like to reference HWS tank temp & grid export to switch the smart port when under temp & exporting after 2pm. ’
Doing it manually through mySigen app at the moment.
Smart port control is not as yet available via modbus and hence not controllable with HA.
But you can pretty much already do what you want with the MySigen app.
You already have a schedule set up for the grid free energy period.
Just set up another schedule from 2PM to whenever makes sense for you, say 4PM, and set it to use only excess solar PV.
You just use the heating element’s power rating in the settings and the system will keep the smart port on while those conditions are met. Then the water heater’s thermostat does the rest.
Thanks mate, appreciate the tip! I didn’t notice the + option to add more than one schedule in the smart port control.
Any idea why the smart port isn’t available via modbus? Is there a channel to make requests for future capability?
I know very little about how/why Sigenergy’s modbus is the way it is. The developers of the integrations are best placed to answer such questions. Not sure they get a lot of interaction with Sig’s software developers though.
Smart port is not the only thing not currently included. e.g. the EVDC unit can be switched on and off but the other controls (e.g. charge rate or the charging mode) are not settable via modbus. There are many other such examples.
Hello All.
I am actually stuck in a big dilama. I had my system installed in September. It was a job to get details and get the modbus sorted. I am still fighting for my EVAC as I still can’t find it. Supplier not giving out the details and my profile is locked down, so not able to do anything. What are my legal rights to get these info so I can self manage?
For those wanting a SigEnergy ‘style’ dashboard with the House animation, Sankey graphs etc worth a look at: GitHub - SpengeSec/Genergy-Dashboard: A Home Assitant energy dashboard in Sigenergy theme · GitHub
Curerntly being worked upon, but if your a Home Assistant Energy Optimiser (HAEO), EHMASS (still ironing some bugs / working around its lack of some sensors) or Energy Manager (www.energymanager.com.au) user, for automating your SigEnergy then also worth looking at, with work to get these tables working with Genergy Dashboard.
Future Decisions
Past Events (reads from the SIG TypQxQ sensors history by default, but there’s options to override the sensors used in card yaml, for non-SIG users).
HAEO / EMHASS versions are similar, just depending upon the sensors / data they make available.
PS. Boring example days… not much buy/sell going on today. 
how is the automation working out sofar? i have the exact same use-case, tibber and sigenergy, and a huge node-red flow trying to have easee win over tibber, but doesnt work…
