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.

I have done a first logging and returned the logfile an a picture with temperatures. Perhaps you can help me and indentify the entities for me, this is Day 2 with EMS-ESP for me...

The second logging is pump on/off

I could identify with your information TS10 and TS11. 😊
So it is eventually possible to read TS6. Then I can connect one more sensor to monitor my heat-exchanger.

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 ?
