SM200 storage transfer system with buffer (J)

[volklend]

I have an solar system with module SM200 and transfer system with buffer (chapter 2.3.10 in the german installation manual).
The pump is driven by PS7 (PS4 in Hardware) an the Temperatures are measured by TS10 and TS11 (TS7 and TS8 in Hardware).
It would be great to have these entity's in the module list.

The TS numbering from Bosch is always confusing.
For the temperatures i expect them in telegram 0x0362, actual we don't know the offsets 4, 12, 14, 18, 22, 24
In telnet or 3.7.1 web status->logger use read 30 362 and compare the searched temperature with a 16bit value, 80 00 means no sensor connected, other values are factor 10, so 02 00 means 512 -> 31,2°C.
If you thinks you have identified the right offset, create a custom entity with device 0x30, type 0x362, offset ?, INT16 and monitor the changing values.
For the pump i expect telegram 0x036A, unknown offsets are 3, 5, 6, 8, 9, 11. Value 03 means off, 04 means on. Use read 30 36A when pump is running and second time when pump is stopped, compare telegrams to find the right offset.

If you need help: Set status-logger to log all, leave page open, got to heating and note the missing temperatures, stop logger after 5 minutes and download log. Attach log here and tell us the temperatures you have noted while logging.
For the pump make a1-2 minute log while pump is running and another while pump is stopped.

Great, i'll add TS10/TS11 to the solar.
The transfer pump seems to be 0x36A, offset 11, for on/off state (04-on, 03-off), INT8
and pump modulation in 0x364, offset 14, INT8.
Can you test and confirm.

So it is eventually possible to read TS6.

Try it, i don't know how the module handles the other inputs.

Hi Michael,
I have tested pump on/off and modulation. It's working...

Now I'm on my way to replace my old "Citrin Solar SLR XT" system with pictures:

and configrable diagrams

Maybe NodeRed is a suitable workbench ?

Hi Michael,
Thank you very much für implementing.

In the between time I have organized a RaspBerryPi and installed
mosquitto, MQTT Explore, Telegraf, InfluxDB, Grafana, ioBroker with adapters for Homematic, KNX, EMS-ESP and Java. Quite hard work, but very interesting. And replaces perfect my oldscool Citrin Solar system.

I found one entity but no Data in the protokols. Do you have Information about "Solareinfluss" ?

[MichaelDvP]

Do you have Information about "Solareinfluss" ?

No, just log the telegrams and change the setting to different values, we should see this in the log.

The Command Value is in 0x2AF Offset 3 INT8 from -1 to -5. 0 is "Disabled".

So in the moment only the diagnostic value adress is unknown. And without your List of unknown temperature adresses, it is quite hard to find...

Maybe you find your -1,1K in 0x2A5 offset 29. It´s int8 with 0,1 K resolution

Der Solareinfluss ist evtl. unterschiedlich zwischen hc1 und hc2. Die hc2-Adressen habe ich noch nicht, könnte ich aber sobald das wetter besser ist jetzt mit meinem zweiten EMS-ESP an meiner anderen Anlage testen...

[volklend]

Gibt es eine Prognose für die offsets ?

[Sbried]

HC2 data is at data type 0x02A6 (HC3 0x02A7 etc, ...). Offsets are identical as for 0x02A5

thank you very much for this information. I will test as soon as the sun shines again 😊

I am thinking about creating my own room influence and calculate a own value for tempautotemp.
Do you think, i can write this item very often without destroying any EEPROM ?
