HMS1600-4T don't communicate with openDTU CM2300A

[nono1024]

Hi all,
I try 2 weeks but with no results.
I'm unable to communicate with my HMS1600 buyed i July.
The SN is 1164A02xxxxx so the inverter is not old.
I try an opendtu CM2300A alone and my openDTU with both NRF24L and CM2300A, the both can't communicate with the HMS
(of course only CM2300A is needed but i got an HM800 too)
I try 868Mhz, 868.75Mhz -10db to +13db different firmware, with or without GPIO2 and 3.
Nothing, i always have partial or middle missing etc.....if you have an idea, i'm hearing.

PS : i'm thinking that my neighbour got hoymiles DTU S box an paired my HMS ?

Thanks a lot

When i look at the console, is see that my HMS send packet with "95 A0......" see RX 868.00 MHz --> 95 A0 28 50 E3 80 16 46 76
But opendtu send packet with "15 A0" see TX RequestFrame 868.00 MHz --> 15 A0 28 50 E3 80 16 46 76

Is that normal ? Thanks
