Use 1 wire dallas as buffertank sensor - J-series

[KelasHA00]

Hi All,
i love the project and have used it alot.
I have in a few threads now read about the idea to use the 1wire channel as a buffer tank sensor.
But none i have read are reporting a solution.

i tried several things but seem to be missing a step.
1st:

Through REST API
http://192.xxx.xxx.xxx/command?SetBufferTemp=Ds18b20#28xxxxxxxxxxxxx
the return is: set optional pcb 'set_buffer_temp' to temp 0.00 (bf)

The TOP46 goes to state: 0 - in principle it works just not as intended, how to get the 1 wire data related as input?

---

2nd:

trying to create a ruleset like suggested here:
#530
@HighlyCompressedAir

on ds18b20#2800000000000000 then
@SetBufferTemp = ds18b20#2800000000000000
end

There is a fatal: internal error lexer_peek #473
and error unexpected token 3560

i think Heisha should be able to it, i simply cannot.
If not, is there a way to read and forward the data to TOP46 in HA?

Best Regards and hope to help others.
