Dry Contact & IR State (WHO 25)
Description¶
Dry Contact Interfaces and some IR Interfaces are able to provide the state of their contacts / IR. The last version of My Home gateways are able to translate the state of these devices in Open Web Net messages.
This function is really useful to know the state of the system and to execute or condition scenarios.
The alarm devices are able to provide the state information in any case, when the burglar alarm system is engaged or not engaged.
For example, if a dry contact interface is used to detect an intrusion on a window, this device can be used to know the status of the windows: opened / closed.
This information can be used:
- to run a scenario: when the window is opened, heating off
- to monitor the window state from a remote application

Communication Examples¶
IR x1 Detection Sequence¶
IR x1 detects presence, after 6 seconds it ends:
| Connection | Time | OWN Frame | Event |
|---|---|---|---|
| Event Connection | 16:51:08:975 | *25*31#1*311## |
Presence detection |
| Event Connection | 16:51:14:861 | *25*32#1*311## |
Presence end |
Software requests the state of IR x1:
| Connection | Time | OWN Frame | Action/Event |
|---|---|---|---|
| Action Connection | 16:45:11:990 | *#25*311## |
State request |
| Action Connection | 16:45:12:068 | *25*31#0*311## |
State requested |
| Event Connection | 16:45:12:068 | *25*31#0*311## |
