Filtering out data out of expected range

ESPHome
1

Im trying to filter out excessive spikes in data coming from my BME680.

Ive fitted 4k7 pull up resisters to the data lines and that has helped but I still get the problem every now and then.

I have been looking for a way to catch this information and eliminate it and found in this issue code that would help.

I am now trying to find a way to update a sensor in HA to display the count_missed results_t.

This guy updated the logs with

ESP_LOGW("main", "Missed Temperature Data %d", count_missed_t);

But I would prefer to replace this line with something that would update a sensor in HA. Ive created a sensor in ESPhome that works but I’m having trouble updating data to it and would be grateful for some help as not very good with C++

So far I’ve added to my original ESPhome code:

 - platform: template
   name: "Lounge Temperature missed"
   id: l_temp_missed
   lambda: |-
     return id(count_missed_t);
   update_interval: 60s

Ive tried creating a global variable count_missed_t and tried sensor.template.publish but have ended up confused with it all.

Any ideas on how I could do this.

Try placing the template under text_sensor: rather than sensor:.

I have tried that but its updating the sensor that’s not working, I think I’m over complicating it.

At the end of the day all I was hoping to do is write a line or two of code in lambda to replace the

ESP_LOGW("main", "Missed Temperature Data %d", count_missed);

in the code below to create and update a HA sensor instead of logging a message in the logs. The HA sensor would then show a count of any errors in the temperature reading.

sensor:
  - platform: bme680_bsec
    temperature:
      name: "L Temperature"
      id: l_temperature
      accuracy_decimals: 2
      sample_rate: lp
      filters:
        - lambda: |-
            float MAX_DIFFERENCE = 2.0; 
            static float last_value = NAN;
            static int count_missed = 0;
            count_missed = 0;
            if (isnan(last_value) || std::abs(x - last_value) < MAX_DIFFERENCE) { count_missed = 0;
              return last_value = x;
            } else {
              count_missed += 1;
              ESP_LOGW("main", "Missed Temperature Data %d", count_missed);
              return {last_value};
            }
