Fair ask…

Just as a contrast, I use a seed studio sensecap indicator (https://www.seeedstudio.com/SenseCAP-Indicator-D1Pro-p-5644.html with openhasp to do a bedside glucose/time display. Works just great.

Here is a screenie.

Looks more versatile than mine:

Mine currently gets all its data via MQTT. How does the Sensecap get its data?

Via mqtt from HA.

bedside:
  objects:
    - obj: 'p1b4'
      properties: 
        text: '{{ states("sensor.blood_sugar") }}mmol/L'
    - obj: 'p1b2'
      properties:
        text: '{{ states("sensor.blood_sugar_trend")}}'
    - obj: "p1b3"
      properties:
        "text": "{% from 'easy_time.jinja' import clock %}{{ clock() }}"
    - obj: 'p1b5'
      properties:
        "text": '{{ states("sensor.blood_sugar_delta")}}'

Cool. My wife likes the look of the device. Can it be used for other features of Home Assistant?

Take a look at Overview - openHASP

Thanks, but I already have four HASP devices including one in a desktop stand. She wants something where she can also see the front-porch camera.

No i don’t believe you can cast a video too it. A picture, yes.

29

Maybe if the picture is updated every ten or twenty seconds? Enough to determine who is at the door.

That might work. Use the openhasp.push_image service. See Example Automations - openHASP

I wanted this format - “Mon 5. Feb” and got it with:

auto now = id(rtc_time).now();
// check valid time
if (now.is_valid()) {
  char dateStr[20];
  // Manually construct the date string cuz %-d is not supported
  sprintf(dateStr, "%s %d. %s", now.strftime("%a").c_str(), now.day_of_month, now.strftime("%b").c_str());
  it.printf(w/2 + hxadd, hy, id(text_small), get_time_color, TextAlign::CENTER, dateStr);
}
