Due to the ongoing lack of Rain in my area I decided to put a Water Level sensor in my Tank. I connected the Level Sensor to Channel 3 of the General Input Unit and used the “Offset” to get the actual level of 92%. See screenshot below I then set the Cbus Measurement Manager to Unit 25 Channel 2 and as expected it also read 92% [ATTACH=full]3170[/ATTACH] Now on Channel 4 of the General Input Unit I have a Moisture Sensor. T he screenshots below shows the reading is 44% in the General Input Unit as it is in the Cbus Measurement Manager, [ATTACH=full]3180[/ATTACH] [ATTACH=full]3171[/ATTACH] A screenshot of the Cbus log below clearly shows that both Channels 3 & 4 of the General Input Unit and Channels 2 & 3 from the Measurement Manager are reading as loaded and are feeding Home-gate through the Cbus Measure Manager with the correct readings. [ATTACH=full]3175[/ATTACH] Now the point of concern is where the Status of the button is set to Rainwater Level in the System IO, it is reading the same (there is a small variable between screenshots) as is the Status which is set to the System IO for the Moisture Sensor. This can be seen below in screenshot of Home-gate System IO and screenshots of Home gate screens.
