I just cannot connect to my battry/Inverter. Tried everything. Any ideas or direction please?
Did your installer enable Modbus for you?
When I look at the Energy Meter/Battery data in Homey, the devices always show the values that the mySigen mobile app shows and labels as âlifetimeâ.
For example, when I open the Energy Meter device in Homey, it shows âEnergy imported = 696.18 kWhâ, which exactly matches the lifetime imported energy in the mySigen app. The same applies to battery charged and discharged energy.
I do see the flow card(s) âWhen imported/exported energy becomes âŚâ, but from what I understand these cards are triggered by real time values, not by energy accumulated over a specific period (e.g. daily). Because the exposed values are lifetime totals, itâs not possible to create even a simple flow such as monitoring daily energy import and sending a notification once a threshold is reached (for example when Iâve imported 20 kWh today).
Would it be possible to add flow cards that can access and use energy data over selectable time ranges? Ideally, these would include: Today, This week, This month, This year, Lifetime (same as mySigen app) and additionally last 24h (as thatâs not the same as Today).
For example, a flow card like:
When âImported energy becomes more than 20kWH during Todayâ â> Send messageâŚ
I have looked and i cnnot see how or where to enable the modbusâŚ
You wonât be able to enable it yourself. Youâll need to ask your installer to turn it on. Once itâs enabled, you wonât see any indication of it in the app, but youâll be able to configure the Homey app (youâll basically just need your systemâs IP address).
This app is awesome!! Thanks a lot, really like it.
Does anyone have any good Flow for notifications when for example SigenStor (battery) or EVDC starts/stops charging? I have tried some simple flows but I´m getting flooded with notifications because the battery seems to start/stop all the time.
I have also tried to get notifications when EVDC starts bi-directional charging (V2H) but then I get notifications booth that it has started charging (to the car) AND that is start bi-directional charging (to the house)..
Hi @Richard_B , thanks for developing this great app. I have enabled MODBUS with the assistance of the installer and setup app in homey with Battery, Inverter, Energy Meter and Plant. All have been enabled for Home Energy. I am curious to understand how the Energy Meter calculates usage, as for me it seems very low in comparison to the household load. In my example the Sig App shows the home usage is a few KW, however the Energy Meter only shows a few hundred watts.
I have created debug report if you have an opportunity to review. Note : I have only enabled today, perhaps things will look different tomorrow.

Thanks Richard
Although allready very nice App I would be even more happy if the Monitoring values would allready Show, now i donât see the 3rd party productie (connected by means of smartport in the gateway) and the intergrated DC charger. At the moment also no values, keep up the good work
Yes, same here. I have two solar arrays: one DC-coupled and one AC-coupled via the smart port. Both are visible in the MySigen app, but not in Homey, so total production and household load shown in Homey are always incorrect. At the moment, I only use the app to view battery charge and discharge rates, SOC, and average cell temperature. It would be great if Homey could reflect all the data available in the MySigen app, and if operation modes could be switched via flows. I guess we can only hope.
Hi everyone,
since the latest updates I no longer receive any Plant data in Homey.
All other values (inverter, battery, grid, etc.) are working correctly and are updating as expected. However, anything that seems to rely on Plant data is no longer showing values. This also affects my widgets â they are no longer displaying data, most likely because they depend on the Plant entity.
Before the updates everything was working fine.
Has anyone experienced the same issue or knows how to fix this?
Is there something that needs to be reconfigured or re-added after the update?
Any help would be greatly appreciated.
Thanks in advance
Hi,
I just added the SigenStor as âplantâ into Homey via Modbus and I had no issues.
I can see all values live and looks good! Maybe remove and readd?
I donât see it in the Energy widget thoâŚ. I added the inverter and the battery as well, those are added to the Energy widgetâŚ. what is the use of âPlantâ?
grtz
As a result, the dashboard widget is also not functioning correctly, since it retrieves its data from Plant.As a result, the dashboard widget is also not functioning correctly, since it retrieves its data from Plant.
Energy Meter is the same as grid import/export; it works the same way as in Sigenergy. Plant reads the overall values in Sigenergy.
For everyoneâs awareness, Plant is not something I have come up with; it is what Sigenergy calls the top level, which may be called System or something similar. You can, for instance, have multiple stacks with SigenStor in the same system - Plant level would include all of them.
On the topic of including values from 3rd party connected solar. Sigenergyâs Modbus implementation is only half-decent; lots of values are missing, and some are not even using the same calculations as in their own app. There is a generic Modbus app for Homey, if someone who has a 3rd party inverter connected can test using that app and figure out which Modbus registers to use, then Iâm happy to add this to the app.
First step, always after an update, if something is not working in Homey, is to restart the app. If something is still not working, you can send me a diagnostic report. Make sure you havenât changed the registry id, it must be 247 as the form states.
Thanks for the reply 
Iâve already done the usual troubleshooting steps:
-
Restarted the app multiple times
-
Also restarted Homey several times
-
Removed and re-added the Plant
Iâm aware of the registry ID requirement and it is correctly set to 247.
At the moment I can still pull the data via Modbus, so the connection itself works.
However, without a working Plant I unfortunately canât use the dashboard widgets, which Iâd really like to have back.
Would be great if we could get the Plant data working again. Let me know if you need a diagnostic report Wenn du willst, formuliere ich es auch etwas kĂźrzer oder technischer.
It works for me, so I would need a diag report.
Restart the app, then after say one minute send the diag report.
I have both a 3rd party inverter (AC coupled) and extra panels connected to Sigenergy via DC. Iâm willing to âplayâ with this if you could provide some more instructions on how to actually get/read that information with the âModbusâ app.
I managed to connect it without any issues but it says âUse flow actions to interact with this deviceâ.
I havenât used the app myself, but I know other users who have. You should use Read Holding Register, I assume.
This is the latest version of the Modbus spec I have.
You can start by trying some of the registries the app uses. You can find them by device type in the registry folder. This is the battery. Reading the state of charge would, for instance, use register 30601 with size 1.
Otherwise, it is about trying to decipher the Modbus sec and figure out what works by trial and error. There were, for instance, several new registers added in version 2.8 - but half of them donât work.
There is an update available within the app, if you run that, it should re-enable this for you.
Not sure what the cause was, but itâs resolved the issue for me just.
