Ok, so I suppose this is not exactly the right way of doing things but has anyone done something similar with reliable results?

I want to be notified if there is water in my geyser drip-tray. What I did was to wire a 2k7 resistor over a zone input. With this my zone registers 'Closed' in the normal or dry condition and as soon as I stick it into a glass of water it goes into an 'Open' state for a few seconds.

This is great but I don't think a zone input is designed to measure such small variations in resistance. Things quickly settle back to a 'Closed' state even with the resistor still in the water.

Does anyone have another cheap idea how to do this?

Ingo,

I'm using these in my home;  one each on my central heating and cold water tanks respectively.

http://www.kemo-electronic.de/en/Home/Garden/M158-Waterswitch-9-12-V-DC.php

The relay closes if water detected across the contacts so can be used on a NO Switch zone.

There's a schematic at this location to show how it all fits together.

Ok, I now have a WaterLevel Switch in place connected to my RIO. How can I write a Response entry to send me a SMS when water is detected? Can I send a custom SMS message or does it follow the GSM configuration in Modules/UCM section and only allow a prefix and some sort of trouble condition message?

RIO Inputs cannot work as Alarm Inputs which trigger alarm types directly

If it is connected to one of the Comfort, SEM or LEM zones, you can modifiy or make a new Alarm Type called Water or Flood, enable dial out to the selected Phone.
Program a Zone Type eg Monitor N/O to point to the Flood Alarm Type
This does not need a Response

To summarise
Zone -> Zone Type Monitor N/O > Alarm Type Flood

The SMS will show the alarm name and zone name
eg My House- Flood Alarm- Basement Flood


If it is connected to the RIO, you have to assign the On Response with the action Do Alarm, zone which wil activate one of the Alarm Types.

I am always amazed at how much you can do with the Comfort system. This just proves it again.

I will move it to a spare Alarm Zone and configure as you suggested.
