[mh] EIB7 and drives/roller blinds

[<th...@ho...>]

Hello together,

I use the mh-tool to control my EIB-Installation (European Installation
Bus). This works quite well for Lighting and other stuff. In order to
control rolling shutters special EIB-actuators exist, known as EIB7
actuators. This had already been taken into account while EIB support was
implemented into misterhouse. The basic support for EIB7-Devices - which
works quite well -  is defined as follows (extract from
~mh/examples/eib_items.mht:

# EIB type 7. Drives, for controlling motors for blinds, windows, etc.
# An EIB drive consists of two different items, with different addresses:
move and stop/step.
# Move is for starting movement up/down, stop/step is for stopping
movement or stepping the motor.
#
# The "address" of a type 7 item is the combination of two addresses:
"move"|"stop/step".
# Note that drives are not readable -- reading a drive may cause it to move!
#
EIB7,     2/1/0|2/1/1,          Kitchen_blinds,        Kitchen|All_Blinds

Unfortunately, the available implementation does regard the current
position of the shutter (if it is up or down), while the hardware is able
to provide this Information. For example, it is possible within EIB to
define two additional EIB-Addresses like 2/1/2 (position: Up) and 2/1/3
(position Down). In this scenario, the actuator will send a signal to
Address 2/1/2 when the shutter reaches the up/open positon and it will
send a signal to 2/1/3 while the shutter reaches the down/close position.

I would like to see the current status (Up/Down) on my buttons, but
currently I do not know how to implement this. You can find an example of
my shutter buttons at http://hoerndlein.dyndns.org . Please Click on
"Jalousie" on the left side navigation.

Maybe somebody has an idea.

Thanks in advance,

Thomas
