HA-sma also compatible with WEBBOX-K1

Webbox Plant: 5 sensors
sma_webbox_0_griegytdy
sma_webbox_0_griegytot
sma_webbox_0_gripwr
sma_webbox_0_msg
sma_webbox_0_OpStt

Generators: 17 sensors Attention! Some sensors are localized into local language!
sma_webbox_1_pac
e.g. sma_webbox_1_seriennummer

Thanks for the feedback
=> everything working fine if I understood correctly ? (I'll close then issue and add K1 to the supported device then)

Yes, works fine. But if I could reduce the interval from 30 sec to 5 sec. it would be fine, the webbox updates the the data every 5 sec. Gruß A. Jacubowsky

You can do that using thé scan_interval parameter (yaml or config flow).

Note that chapter "4.3 Query Interval" of the Sunny Webbox RPC User Manual specifies that the interval should not be less than 30s

[AlexJacu]

OK. But I know they are very conservative. Additional, the webbox are using RS-485 connection with the inverters Alexander Jacubowsky Jacubowsky EDV

There is probably some margin but not sure why you would need faster update rate (30s is already 120 measurements/hour for each sensor and gives you very good insight/resolution already) ... but feel free to experiment with more aggressive scan_interval values :-)

For my records, what FW version is running on your webbox K1 ?

10 seconds was a bit to short, the updates took 12 to 14 sec. so i changed to 15 sec. update.
At 15 sec. Interval, it results in 17 on HA. So I have set it to 13 sec. and the result in HA is 15 sec., fine for me.

Hint: check the delay in update and reduce the updateinterval by that delay. eg. be delay ist 2-3 sec. so i set to 13 sec. and in HA the chart hast to 90% a 15 sec. stepping.

Please note, that my HomeAssistant is running on a virtual machine on an performance server (4 CPU and 6 GB RAM) !!!
Connection with webbox is via LAN! and konverter are connected via RS485 cable !
Please be carful to reduce the 30 sec. limit, if HA is installed on a Rasberry or other slow devices !!

Just added your K1/FW version to the list of supported device, thanks for reporting.
Wrt scan_interval, the critical element won't be HA but the webbox CPU probably (running other tasks like regular updates to sunny portal if enabled)
=> if you observe strange behaviors, try to increase scan_interval back to its minimum spec'ed value

yep. the webbox is in the cabinet and is cooled together with the server

[AlexJacu]

One point ia have, in the night, when the konverters are offline i get an failure text (Not available), instead of 0 W (pac)

[jpcornil-git]

When the inverter disconnects itself from the grid a number of parameters becomes 'unavailable', this is expected.
