LoxBerry::IO::mshttp_send_mem

Sends a value to a Loxone Miniserver input, or sends multiple values to multiple inputs. The function automatically saves the last state and only sends values that have changed.

Please see the documentation of LoxBerry::IO::mshttp_send for parameters. Parameters and return values are fully compatible to this function.

The difference to the mshttp_send function is that it remembers recently sent values, and does not re-send non-changed values.

That memory is kept on RAM disk - therefore the memory works not also during a single runtime, but also over several calls that init new processes every time (e.g. calls from the webinterface, or calls from a cronjob).

The function uses different mechanisms to check, if it should exceptionally send all values, not only the diff:

• After a LoxBerry reboot, the memory file on the RAM disk is empty → Every new incoming parameter and value is sent
• LoxBerry::IO defines a variable $LoxBerry::IO::mem_sendall_sec that defaults to 3600 seconds (1 hour). A call after 1 hour will clear the cache and all values will be re-sent.
• LoxBerry::IO checks the Miniserver after at least 5 minutes if it possibly was rebooted. If so, the cache is cleared to and every value is sent again.

These parameters are shared for mshttp_send_mem and msudp_send_mem.

# Set this variable directly before the function call to override the cache and exceptionally submit ALL values.
# After every function call, the function resets the value to 0.
$LoxBerry::IO::mem_sendall = 1;
 
# Change the setting after what time (seconds) the cache should be cleared and all values should be sent.
# Default value is 3600.
$LoxBerry::IO::mem_sendall_sec = 7200;
