Multiple devices using rest

Development
1

I have two PLCS and am trying to use rest sensor commands to get state information. Only one PLC (the first) gets its state read…the other remains blank. I have tried this configuration:

rest:
  - resource: http://192.168.12.11/state.xml
    scan_interval: 16
    sensor:
      - name: PLC1Relay1
        value_template: "{{ value_json['datavalues']['relay1'] }}"
      - name: PLC1Relay2
        value_template: "{{ value_json['datavalues']['relay2'] }}"
      - name: PLC1Relay3
        value_template: "{{ value_json['datavalues']['relay3'] }}"
      - name: PLC1Relay4
        value_template: "{{ value_json['datavalues']['relay4'] }}"

rest:
  - resource: http://192.168.12.12/state.xml
    scan_interval: 16
    sensor:
      - name: PLC2Relay1
        value_template: "{{ value_json['datavalues']['relay1'] }}"
      - name: PLC2Relay2
        value_template: "{{ value_json['datavalues']['relay2'] }}"
      - name: PLC2Relay3
        value_template: "{{ value_json['datavalues']['relay3'] }}"
      - name: PLC2Relay4
        value_template: "{{ value_json['datavalues']['relay4'] }}"

and this

rest:
  - resource: http://192.168.12.11/state.xml
    scan_interval: 16
    sensor:
      - name: PLC1Relay1
        value_template: "{{ value_json['datavalues']['relay1'] }}"
      - name: PLC1Relay2
        value_template: "{{ value_json['datavalues']['relay2'] }}"
      - name: PLC1Relay3
        value_template: "{{ value_json['datavalues']['relay3'] }}"
      - name: PLC1Relay4
        value_template: "{{ value_json['datavalues']['relay4'] }}"

  - resource: http://192.168.12.12/state.xml
    scan_interval: 16
    sensor:
      - name: PLC2Relay1
        value_template: "{{ value_json['datavalues']['relay1'] }}"
      - name: PLC2Relay2
        value_template: "{{ value_json['datavalues']['relay2'] }}"
      - name: PLC2Relay3
        value_template: "{{ value_json['datavalues']['relay3'] }}"
      - name: PLC2Relay4
        value_template: "{{ value_json['datavalues']['relay4'] }}"

but neither work. Additionally, I am using curl GET to turn on and off the relays, but the switches still do not incorporate the state of the PLC relay so the switch slides on then off. Is there a better way to do this or a card that will incorporate both the rest state and the curl commands for on/off?

The output of my state.xml looks like this:

<datavalues>
<input1state>0</input1state>
<input2state>0</input2state>
<input3state>0</input3state>
<input4state>0</input4state>
<relay1state>0</relay1state>
<relay2state>0</relay2state>
<relay3state>0</relay3state>
<relay4state>0</relay4state>
<units>F</units>
<sensor1>x.x</sensor1>
<sensor2>x.x</sensor2>
<sensor3>x.x</sensor3>
<sensor4>x.x</sensor4>
<s1Alrm>0</s1Alrm>
<s2Alrm>0</s2Alrm>
<s3Alrm>0</s3Alrm>
<s4Alrm>0</s4Alrm>
<count1>0.000</count1>
<count2>0.000</count2>
<extvar0>0.00</extvar0>
<extvar1>0.00</extvar1>
<extvar2>0.00</extvar2>
<extvar3>0.00</extvar3>
<vin>15.879</vin>
<vinAlrm>1</vinAlrm>
<serialNumber>00:0C:C8:03:A1:30</serialNumber>
<time>1262445935</time>
</datavalues>

The second example is the correct syntax (only one rest: integration key). Your templates don’t appear to be accessing the correct keys though. There is no xml tag called “relay1”, it is “relay1state”.

Try:

value_template: "{{ value_json['datavalues']['relay1state'] }}"
3

Only PLC1’s relay states are being read. Even relay1 worked, but you are correct that I should change it to relay1state. Any ideas on why it is only reading PLC1?

Did you remove the second occurrence of rest: ?

Yes

est:
  - resource: http://192.168.12.11/state.xml
    scan_interval: 16
    sensor:
      - name: PLC1Relay1
        value_template: "{{ value_json['datavalues']['relay1state'] }}"
      - name: PLC1Relay2
        value_template: "{{ value_json['datavalues']['relay2state'] }}"
      - name: PLC1Relay3
        value_template: "{{ value_json['datavalues']['relay3state'] }}"
      - name: PLC1Relay4
        value_template: "{{ value_json['datavalues']['relay4state'] }}"
  
  - resource: http://192.168.12.12/state.xml

      - name: PLC2Relay3
        value_template: "{{ value_json['datavalues']['relay3state'] }}"
      - name: PLC2Relay4
        value_template: "{{ value_json['datavalues']['relay4state'] }}"

Any errors in Settings-> System-> Logs?

It seems to be reading both PLC’s values just fine. Perhaps it just keeps overwriting the value of the second PLC? Tried to change the intervals but nothing is written for the state of the second PLC

Have a close look at the error message:

2023-06-15 16:28:44.134 DEBUG (MainThread) [homeassistant.components.rest.sensor] JSON converted from XML: {"datavalues":{"digitalInput1":"0","digitalInput2":"0","digitalInput3":"0","digitalInput4":"0","relay1":"0","relay2":"0","relay3":"0","relay4":"0","vin":"12.5","register1":"0","oneWireSensor1":"x.x","oneWireSensor2":"x.x","oneWireSensor3":"x.x","oneWireSensor4":"x.x","utcTime":"1686860923","timezoneOffset":"-14400","serialNumber":"00:0C:C8:04:38:0F","downloadSettings":"1"}}

It’s complaining about a missing relay4state and it’s right: there isn’t one. This response contains relay4 not relay4state. Have a careful look at the XML response from each PLC and see what keys it actually contains.

So PLC2 is not returning the same xml tags as PLC1. Try this:

rest:
  - resource: http://192.168.12.11/state.xml
    scan_interval: 16
    sensor:
      - name: PLC1Relay1
        value_template: "{{ value_json['datavalues']['relay1state'] }}"
      - name: PLC1Relay2
        value_template: "{{ value_json['datavalues']['relay2state'] }}"
      - name: PLC1Relay3
        value_template: "{{ value_json['datavalues']['relay3state'] }}"
      - name: PLC1Relay4
        value_template: "{{ value_json['datavalues']['relay4state'] }}"
  
  - resource: http://192.168.12.12/state.xml
    scan_interval: 16
    sensor:
      - name: PLC2Relay1
        value_template: "{{ value_json['datavalues']['relay1'] }}"
      - name: PLC2Relay2
        value_template: "{{ value_json['datavalues']['relay2'] }}"
      - name: PLC2Relay3
        value_template: "{{ value_json['datavalues']['relay3'] }}"
      - name: PLC2Relay4
        value_template: "{{ value_json['datavalues']['relay4'] }}"

Oh geez…you are very, very right! I should have looked closer (I think I saw the same formatted output ans naturally assumed the same manufacturer would use same names for different models) and thank you for pointing this out.
