Trying to add a non-sonoff flow sensor

[tmorse305]

I'm trying to add a non-sonoff flow sensor to eisy.

I know the topic and I'm receiving MQTT packets from the sensor but the payload includes the word "flow".

Log file:

2025-08-08 11:51:45.574 paho-mqtt-client- udi_interface INFO Controller:_on_message: Received _on_message {"flow":16.16} from droplet-BA7C/state

2025-08-08 11:51:45.575 paho-mqtt-client- udi_interface INFO Controller:_on_message: _else: Payload = {"flow":16.16}, Topic = droplet-BA7C/state

 

I've tried combinations of "type" and "status_topic" but to no avail.  

 

How do I deal with the label "flow" in the payload?

 

Thanks.

@tmorse305 , 

have you tried changing your topic in your set-up from:

droplet-BA7C/state

to:

droplet-BA7C/state/flow

Hi @sjenkins, thanks for the suggestion.  I did try that.  The result is that the packets are not recognized by MQTT so there is no activity recorded in the log.  

I was looking at some of the node files, the MQSensor.py in particular shows the payload being tested for text.  Here is an example:

 # temperature
        if "temperature" in data:
            self.setDriver("CLITEMP", data["temperature"])
        # heatIndex
        if "heatIndex" in data:
            self.setDriver("GPV", data["heatIndex"])

I probably need to create a custom file to test for "flow" but not sure how to go about that.

This is the flow sensor.  Maybe if there were others using it we might be able to have someone create it.

Droplet the Smart Home Water Sensor - Hydrific, part of LIXIL

It currently has an integration for Home Assistant, but it would be great to create a direct connection to eisy.
