Add Var3 value to home assistant entities

[peteDDD]

I am just getting started with Tasmota and have a device connected to Home Assistant through MQQT. Easy enough. I now see entities for each of the relays on my device. I also want to have the value of Var3 as an entity on Home Assistant. Here is what I have tried but I can't find the entity on HA. Surely I must be missing some detail here...

First, my topic:

I added a Rule2

16:24:58.078 CMD: Rule2
16:24:58.085 MQT: stat/tasmota_HAWatchdog/RESULT = {"Rule2":{"State":"ON","Once":"OFF","StopOnError":"OFF","Length":62,"Free":449,"Rules":"Rule3 ON Var3#State DO Publish stat/%topic%/VAR3 %value% ENDON"}}

on Home Assistant, I added an mqtt sensor in configuration.yaml

    - name: "HA Watchdog Reset Count"
      unique_id: ha_watchdog_reset_count
      state_topic: "stat/tasmotakaufplug4/Var3"
      value_template: "{{ value }}"

using MQTT Explorer, I can see the message being published.

stat
tasmota_HAWatchdog
RESULT = {"Var3":"7"}
POWER2 = OFF
POWER1 = ON
POWER3 = ON

All that is missing for me now is finding the sensor on Home Assistant. I search for "Var3" and "HAWatch" but I don't find it.
What part of this am I missing? Thank you.

Use SetOption4 if you want the topic to include the command name (instead of RESULT)

@sfromis Thank you. That helped. And now my final solution for anyone playing along at home...

0: SetOption4 1
1: Use Mem1 instead of Var3 so that I can keep the count between restarts.
2: Publish a specific topic rather than just Mem1 (which also comes for free apparently). Set up to receive the topic on Home Assistant in configuration.yaml

mqtt:
  sensor:
     - name: "TasmotaHAWatchdog Reset Count"
      unique_id: ha_watchdog_reset_count
      state_topic: "stat/tasmota_HAWatchdog/ResetCount"
      value_template: "{{ value }}"

3: Publish the value of Mem1 to the topic at restart (in Rule 1) and when it changes (in Rule 2). (NOTE, COMMENTS BELOW ARE ONLY FOR EXPLANATION AND CANNOT BE INCLUDED IN THE RULES. SEE THE SINGLE LINE RULE FURTHER DOWN FOR THE UNCOMMENTED VERSION.

Rule1
  ON system#boot DO backlog Power1 1; Power3 1; Var1 1; BlinkTime 10; BlinkCount 0; Power2 Blink; Var2 0 ;  // Outlet on, Blue LED on, Red LED slow flash (appears purple)
  Publish stat/tasmota_HAWatchdog/ResetCount %Mem1% ENDON  //Publish persistent value of Mem1

 ON Var1#State>16 DO Var1 16 ENDON  // limit interval to 16 minutes

  ON Time#Minute|%var1% DO backlog Var2 0; BlinkTime 5; Power2 Blink; WebQuery http://192.168.1.220:8123/ GET 100 ENDON // clear flags, check Home Assistant, more rapid Red LED flash (flashes purple)

  // Step 2: Handle Home Assistant result and if down, test Router
  ON WebQuery#Data=Done DO IF (%var2%==0)  Var1 1; Power2 BlinkOff; Power1 1; Power2 0; Power3 1 ENDON  // HA connected, no need to test Router
  ON WebQuery#Data$!Done DO IF (%var2%==0) Var2 1; WebQuery http://192.168.1.1/ GET 100 ENDIF ENDON // HA not connected, test Router

  // Step 3: Handle Router result 
  ON WebQuery#Data=Done DO IF (%var2%!=0) RuleTimer1 1 ENDIF ENDON  // HA down, Router Up: trigger RuleTimer 1  Use RuleTimer since we need to use backlog to sequence the delay
  ON WebQuery#Data$!Done DO IF (%var2%!=0) BlinkTime 2 // (HA Down), Router down: Flash more rapidly  (minimum BlinkTime value is 2)
  ON Rules#Timer=1 DO backlog MULT1 2; Power1 0; Power3 0; Delay 30; Power1 1; Power3 1; ADD3 1 ENDON

Rule2 ON Mem1#State DO Publish stat/tasmota_HAWatchdog/ResetCount %value% ENDON

Here is Rule1 on a single line:
Rule1 ON system#boot DO backlog Power1 1; Power3 1; Var1 1; BlinkTime 10; BlinkCount 0; Power2 Blink; Var2 0; Publish stat/%topic%/Mem1 %value% ENDON ON Var1#State>16 DO Var1 16 ENDON ON Time#Minute|%var1% DO backlog Var2 0; BlinkTime 5; Power2 Blink; WebQuery http://192.168.1.220:8123/ GET 100 ENDON ON WebQuery#Data=Done DO IF (%var2%==0) Var1 1; Power2 BlinkOff; Power1 1; Power2 0; Power3 1 ENDIF ENDON ON WebQuery#Data$!Done DO IF (%var2%==0) Var2 1; WebQuery http://192.168.1.1/ GET 100 ENDIF ENDON ON WebQuery#Data=Done DO IF (%var2%!=0) RuleTimer1 1 ENDIF ENDON ON WebQuery#Data$!Done DO IF (%var2%!=0) BlinkTime 2 ENDIF ENDON ON Rules#Timer=1 DO backlog MULT1 2; Power1 0; Power3 0; Delay 30; Power1 1; Power3 1; Mem1 %Mem1% + 1 ENDON

We can see that both Mem1 and ResetCount get published, but ResetCount is in a form similar to POWER1, etc.

And in Developer tools/states on Home Assistant, we can see the sensor which can now be used in dashboards:
