MQTT sensor problem with numbers and messagemap

---

Hello,
I have a problem with my mqtt sensor. I’d like to use ‘number’ as data type. But then the messagemap does not work. With data type ‘string’ it works. But unfortunately I cannot use the graph in this case.

So I’m not an expert at this point. Does anyone have an idea why it’s going wrong? Is there a bug in the function?

When I first put the indexes to the messagemap I see only “unknown” as value. And when I first put in the values I only see the original value as a number.

I found the location in the mqtt-sensor.coffee script. In the second case the line if attr.messageMap && attr.messageMap[message] is not true because of the condition attr.messageMap[message]. In the first case it steps over to the last else block. I think it’s quite logical, but why is the index not recognized. I send a value 2 and I have 2 in my messagemap. But it doesn’t work.

          else
            if attr.type == 'number'
              if attr.division
                payload = (Number(message) / attr.division)
                @setValue(payload, name)
                return
              if attr.multiplier
                payload = (Number(message) * attr.multiplier)
                @setValue(payload, name)
                return
              if attr.messageMap && attr.messageMap[message]
                payload = Number(attr.messageMap[message])
                @setValue(payload, name)
                return
              else
                payload = Number(message)
                @setValue(payload, name)
                return

Thank you very much

I think now there is a logical problem. When type is defined as number, pimatic (or mqtt script?) does not allow to show text in the webinterface. So a replacement of numeric values with text out of the messagemap is not possible. Looks like this was never tested during development.

Where comes the string from?
Are you using Node Red?
If yes: Put a Function-Node between your Sensor and Pimatic.
The Code is simple:

msg.payload = Number(msg.payload);
return msg;
