|
The following is a possible configuration file for common covers that use a motor with 2 inputs.
|
|
Only one should be powered at a time (interlocking) to either move the cover up or down. For this
|
|
the `Sonoff Dual R2 <https://www.itead.cc/sonoff-dual.html>`__ can be used which has two independent
|
|
relays. Additionally this configuration allows the single button on the Sonoff to control the motion
|
|
by cycling between: open->stop->close->stop->...
|
|
|
|
These kind of motors automatically stop when the end of the cover movement is reached. However,
|
|
to be safe, this automation stops powering the motor after 1 minute of movement. In the rare case
|
|
of the end-stop switch in the motor failing this will reduce the risk for damage or fire.
|
|
|
|
Of the four main components (button sensor, 2 relays switches and the cover), only the cover will be
|
|
visible to the end-user. The other three are hidden by means of not including a ``name``. This is to
|
|
prevent accidentally switching on both relays simultaneously from Home Assistant as that might be harmful
|
|
for some motors.
|
|
|
|
.. note::
|
|
|
|
Controlling the cover to quickly (sending new open/close commands within a minute of previous commands)
|
|
might cause unexpected behaviour (eg: cover stopping halfway). This is because the delayed relay off
|
|
feature is implemented using asynchronous automations. So every time an open/close command is sent a
|
|
delayed relay off command is added and old ones are not removed.
