Unexpected Inverter data #42

First off everything works great. It's just that sometimes I get the strange data about an inverter that is not mine. Not sure if it's because my packet count is low (25 packets). I set it low so there is less latency as I'm calling the API every 5 seconds. I have 2 MS4024PAEs but every now in then I pick up some other models (MS2012E, MS4448PAE, MS4124E) that would then cause some crazy voltage readings

In HA (Home Assistant) I have added logic to setting the sensor state value to make sure It's only recording data for the correct Inverter Model (MS4024PAE) and that if the API is down for some reason it will just keep the last value so I dont have a bunch of weird looking data.

`
template:

sensor:
- name: "Magnum Inverter Volts"
  unit_of_measurement: "V"
  state: >
  {% set model = state_attr('sensor.magnum_inverter_master', 'model_text') %}
  {% set ignore = ['unknown', 'unavailable'] %}
  {% if state_attr('sensor.magnum_inverter_master', 'vdc') not in ignore %}
  {% if model == 'MS4024PAE' %}
  {{ state_attr('sensor.magnum_inverter_master', 'vdc') }}
  {% else %}
  {{ states.sensor.magnum_inverter_volts.state | float(default=0)}}
  {% endif %}
  {% else %}
  {{ states.sensor.magnum_inverter_volts.state | float(default=0)}}
  {% endif %}
  device_class: voltage
  state_class: measurement
  `

Just wondering if anyone else is getting strange data

Thank you,

Kevin

Also I sometime get a PT100 charge controller (Had one for a week before it gave up the ghost) and it will show up with NaN in a few values. Home Assistant doesn't like this and says "REST result could not be parsed as JSON"

Here is what the JSON data looks like
