The UnitID on my Sunny Explorer = … ? 16… ?
I’m trying to get this working with node red but keep getting errors.
Hi,
Look again on my screenshot. The UnitID is in the Modbus Section. You are looking outside the Modbus Section
Thanks Chris_ka. But i dont see something else that looks like it. For know i use 3. And its working fine 
Hi.
I’m also using 0.118.5 (homeasistant installed on raspberry pi4) and modbus to read sma sunny boy 3.6 tl inverter.
Till 0.118 every thing worked fine, now I can’t see the inverter parameters.
I tried via shifting registers with +1 and also via -1 but nothing changed.
Do you have any hints?

Can somebody helping me?
When my SMA is off (by night) i got weird values on my Actual power and the Power Fases.

Anyone having issue with Modbus integration not showing values? For some reason I do not see any values for the last few days. When I login to portal I see data still.
Hi!
did u find a solution?
I have sunntboy 2.5 with modbus integration.
During night my HA frontend brakes because i have tons of errors generated from unreachable sunnyboy.
2021-06-02 23:09:37 ERROR (SyncWorker_58) [homeassistant.components.modbus.modbus] Pymodbus: Modbus Error: [Input/Output] Modbus Error: [Invalid Message] No response received, expected at least 8 bytes (0 received)
2021-06-02 23:09:40 ERROR (SyncWorker_45) [pymodbus.client.sync] Connection to (192.168.1.16, 502) failed: timed out
is it true that the sunnyboy doesn’t work during night and goes into night mode?
I dunno how to solve this issue, i have an error every few seconds.
Thank you for anyone can help
Hello,
I have the same issue.
I get verry sparce data over the modbus from my sma converter.

Any ideas?.
Hi chris_ka,
I have tried your code for the template sensor, as my inverter shows -2,147,483,648W during night time which screws up my Grafana chart. I had no luck, it does not show up under Sensors in the Dashboard 
What am I doing wrong?

0Hi Stefan,
to use a template sensor you need to define it as such by using
- platform: template
section instead of - platform: modbus
Hi Chris,
thank you, stupid mistake on my side - it works now
HI
Untill now I was using Chris’s node red setup and MBolt modbus code. With current version of home assistant modbus changed and I cant see anymore my solar power. I can see power consumption from home manager but nothing from invertor. Would anyone be able to help what needs to be chnaged in the modbus code (yaml) from MBolt to get it working again? I have tried the home assistant official solar integration but getting connection error so that doesnt work.
Hello.
In my case modbus platform configured for sma reading is working well… Exept for some modbus communication dopout. Tipically one, maximum two times per day I need to restart Ha because every sensor from modbus sma gone to value 0 (zero)
After HA restart, everything is ok.
This happened only with new integration. Before Core update everything was ok.
Are there any settings to put, to avoid this behaviour.?

I’m seeing this same issue on my SMA Tripower 8.0. The inverter reboots once in a while during nighttime. Afterwards the modbus intergration doesn’t start anymore unless I restart my HA instance.
I think this will be fixed in 2021.7.4.
See here: Allow pymodbus to reconnect in running system (not startup) by janiversen · Pull Request #53020 · home-assistant/core · GitHub
Hi Daniele,
Ciao.
I have inverter with modbus, original integration and SMA Energy meter addon.
With the last update the integration and the Energy meter addon doesn’t show me the current house consumption (il consumo della casa istantaneo, che esso sia da grid o da pv o aggregato)
Do you have the sensor working? Is there a way through modbus to have that sensor?
Thank you
Grazie mille!
Hi.
Unfortunately I didn’t have that meter.
I bought a shelly PM, and power from grid a da from/to batteries is measured with this.
With modbus integration I’m able to read data from sma., with last update of core, without any interruption.
I fixed my SMA Modbus configuration and it’s working again:
