hi i have taken the reed switch out of a sonoff snzb-04 and conecter a rain sensor thing im using the Simulated Water Sensor driver but when its dry it shows as wet and when its wet it shows as dry ad i dont know how to make it right . i want to use it as a rain sensor ,any help would be great thanks.

Hi, @montyfert!

Is this still a Zigbee device?
Groovy-based integrations (like DTH) are part of our Legacy platform (take a look at this announcement) so, I suggest you start with Edge drivers instead so your efforts aren’t in vain.
However, in the case of a DTH, you should check the parse() method, where all the messages are received and “translated” to the corresponding capability values.

hi yes it is still a zigbee driver ,unfortunately i wouldnt know how to make an edge driver, im completely baffled by the dth things.
i compare my technical knowedge to a crow trying to knit lol .

Can you share the DTH that you’re currently using, please? Just to take a look at it.

for some reason its not wotking at all today with the simulated water sensor dth i changed it to the Z-Wave Water Sensor dth and is working again but wet when its dry etc lol

this is the dth

If the DTH that works for your device is Z-Wave Water Sensor, then, you can create a copy in your IDE and make the changes necessary.
Based on your description, you need to check the value of these parameters:

github.com

SmartThingsCommunity/SmartThingsPublic/blob/master/devicetypes/smartthings/zwave-water-sensor.src/zwave-water-sensor.groovy#L116


      
          
          
def parse(String description) {
          	def result = null
          	if (description.startsWith("Err")) {
          		result = createEvent(descriptionText: description)
          	} else {
          		def cmd = zwave.parse(description, commandClassVersions)
          		if (cmd) {
          			result = zwaveEvent(cmd)
          		} else {
          			result = createEvent(value: description, descriptionText: description, isStateChange: false)
          		}
          	}
          	log.debug "Parsed '$description' to $result"
          	return result
          }
          
          
def sensorValueEvent(value) {
          	def eventValue = value ? "wet" : "dry"
          	createEvent(name: "water", value: eventValue, descriptionText: "$device.displayName is $eventValue")
          }

To print those values you can use this line before createEvent:

log.info "description: ${description}"

There is where the events for the capability are generated and you will be able to check why are the events reversed or translate them accordingly.

This process can be a little tedious because there’s no documentation about Groovy DTH anymore.

hi sorry not sure what you mean

thanks for the help
but its sorted now thanks someone sugested creating a virtual water edge driver and using automations to controll that and it working great . thanks
