OTGW: Read-Data Request Data-ID 11 out of range

Postby Templar » Mon Oct 09, 2017 6:45 pm

I noticed some OTGW behaviour regarding Data-ID 11 yesterday. The OTGW requests ('R' message) Data-ID 11 with an ever increasing Index number, exceeding the reported number of TSP's (Data-ID 10). The boiler reacts with Data-Inv because the TSP-index is out-of-range.

In my case the Remeha Tzerra boiler returns the value 45 as the number of TSP's (Data-ID 10). And returns Data-Inv at TSP index no. 0 = x > 44 (Data-ID 11) .

I am using OTGW 4.2.5.
