Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Seplos isn't an inverter, it's a BMS
Do you mean sofar?
Sorry meant sofar.
Once it supports Modbus and you can readily obtain a list of the relevant Modbus registers, I would have thought the world is your oyster from an automation perspective.
The sofar to ha integration was pretty straightforward though so looking for something similar
Can i simply turn off my eddi from home assistant?
Some days/evenings i don’t need it to heat my water after lunch time. Would rather fill the battery or export to grid
Assuming you are using the MyEnergi integration, there should be a select you can use.
select.myenergi_eddi_operating_mode
Yep
Is there a guide anywhere for controlling the inverter? How to set it to charge the battery at certain times from the grid (or to stop)?
Just wondering what I am doing wrong here. Trying to send a notification when the temp in the cylinder drops to my phone but it does not appear to triger.
Seems similar to mine for the car charger:
- id: '1671655319801' alias: Car Charger is Charging description: '' trigger: - platform: numeric_state entity_id: sensor.shellyem_charger_channel_1_power above: 1000 for: hours: 0 minutes: 2 seconds: 0 condition: [] action: - device_id: ba58fdfc38a712a22db91de226664f1c domain: mobile_app type: notify message: Car Charger is Charging mode: single
Wonder do you have to provide a device_id and domain like I did?
Thanks for the reply.
The notification test to the phone works so that piece seems ok. It's the automation not kicking in to run when the temp drops to triger the alert is where I am stuck.
Oh I think I know what it is. The trigger only happens as a one-time event when the tank temperature transitions from 50 degrees to less than 50, it does not trigger if the water is already lower than 50. So you'll need to boost it above 50 and then let it drop again.
I have tried that and testing again. Temp is currently at 48 degrees.
Values changed to 48.

And you reloaded the script engine? I often had to restart the whole HA service to get these scripts working.
Yeah I have restarted. I have tried to set it up from the integration instead as another test so will report back.

Nothing wrong with the automation. Tested it myself for pig iron.

I don't have the Eddi addon board, but have separate temperature sensors from my solar thermal system.
Suggest you enable developer mode and manually set the value of sensor.myenergi_eddi_temp_tank1
sensor.myenergi_eddi_temp_tank1
Also have a look at the traces of the automation. They are quite helpful.
Just to give a quick update the automation ran sucessfully when it was created using the device and entity ID from the Myenergi integration.
As always thanks to the helpful posters here with their assistance.
Can I ask about the temp sensor you use? I have an eddi and relay board but I never installed them cos I want to export as much as possible.
Where did you get the temp sensor? Where do you have it mounted on the tank?
are you using it for anything clever :)
The temp sensor I use I got from Amazon.de its a standard PT1000
I have installed it here as the Aquastat pocket is below the immersion so was no use to get correct readings.
I needed to replace the blank with this.
I am not on deemed export so heating with gas is significantly cheaper via gas. 10c v €1-€2 so prefer to export and heat water as required.
Here is an example of top v bottom readings.
Anyone using a Huawei inverter with home assistant and if so how difficult is it to setup?. Still looking to get solar and got a quote with a Huawei hybrid inverter, but found a thread on home assistant forum and seemed a bit intimidating not straightforward to connect a Huawei inverter to home assistant. Would like to hear if anyone else has that setup working.
Yeah. It’s easy to get working. Happy to share my settings if you need. Just DM me.
Cheers, are you able to connect directly to your existing wifi connection? I see serial ports and huawei dongles mentioned in some of the options.
@HotSwap, I'm interested too please. I've a Huawei inverter and tried but got lost tbh and I'd consider myself handy enough normally with tech stuff. Cheers
Post for everyone to learn from if possible?
Decision time for an inverter for me.... Sofar with sofar2mqtt seems very controllable from Home Assistant....
The other one for consideration is the Sunsynk inverters.....
Anyone feel strongly for one over the other (ideally post experience with both!)?
Bonus points if one is easier to self install Vs another but monitoring and controlling (future battery purchase planned) via HA is the priority.
Any inverter with Modbus control will do. Sofar, Sunsynk/Deye, Solis. They are all the same.
You just enable the integration and then select the “Network” connection method. You use the IP address that the inverter is connected to your Wi-Fi on. And enter the admin username and password. The only one bit that needed to be done on the inverter was enabling “Modbus over IP” (https://forum.huawei.com/enterprise/en/modbus-tcp-guide/thread/667250677153415168-667213868771979264) or something like this in the admin settings of the inverter. It was all well documented from what I remember.
Its all documented here:
Give it another try and if you hit any issues let me know.
The only one thing I can remember is that if your connected to the inverter locally using the “commissioning” section in the fusion solar app; the inverter will reject the modbus connection from home assistant; and also when home assistant is connected you cannot connect from the app without first disconnecting the integration in home assistant.
The only reason I have to connect to the inverter directly now is to modify the “charge and discharge” times that are used when the inverter is in TOU mode.
Sunsynk if you want proper charge/discharge rates and pretty seamless integration with HA (use solar-assistant), stay away from Solis and their false advertising, we've all been through that nonsense.
Cheers for instructions. Did you need a dongle or could you connect directly to the inverter? And did you need your installers login details or can it be set up without that?
I like the look of solar assistant but don't fancy another RPi running just for comms with it. Is there any other method? I'm leaning towards the Sunsynk.
