I started playing with this last week, ended up using the modular watch face to include 4 elements available in the Glances API that @jenslj linked to.
Title (Top in blue)
Text (Middle)
Subtext (Bottom)
Percent (Can be anywhere where you can put an icon, in my example it’s bottom right and was set to ‘count’ rather than percentage in my screenshots… doh!)
I now have 3 main different modules that change depending on presence at home:
If I’m home:
-
Title: Current Weather Summary at Home
-
Text: Home Energy Consumption in Watts, Nest Thermostat Temperature (Soon to be replaced with a house average across multiple temp sensors), and How many times my letter box was opened today (Between midnight > midnight)
-
SubText: How many lights are on, How many Doors and/or Windows are open
-
Percentage(bottom right): Probability of rain at Home.
If I’m not Home but someone else is Home:
-
Title: Alarm Panel Status, followed by the initials of people at home (could be any combination of 3 other people)
-
Text: Home Energy Consumption in Watts, Nest Thermostat Temperature (Soon to be replaced with a house average across multiple temp sensors), and How many times my letter box was opened today (Between midnight > midnight)
-
SubText: How many lights are on, How many Doors and/or Windows are open
-
Percentage(bottom right): Probability of rain at Home.
When no one is home:
-
Title: Alarm Panel Status, Status of my presence simulation script.
-
Text: How many times someone has triggered front door motion while no one was at home, and How many times my letter box was opened today (Between midnight > midnight)
-
SubText: How many lights are on, How many Doors and/or Windows are open
-
Percentage(bottom right): Probability of rain at Home

Automation:
NOTE: Remember to add “seconds” to the time trigger, other wise it will trigger a Pushover API update every second on the half hour (60 times), 86,400 times in a month! limit for free Pushover messages is 7,500 a month, I learnt this the hard way, haha!
- alias: Update Pushover Complication
initial_state: 'on'
trigger:
- minutes: '/30'
seconds: 00
platform: time
action:
- service: shell_command.pushover_glance
I have also tagged this as an action:
- service: shell_command.pushover_glance
in automations that trigger on presence changes or alarm state changes (doesn’t seem to be using too many API posts to PO) using around 50 a day in total, so 1,500 a month.
This is how I’m using my counters and also resetting them in Automations:
- alias: Front Door Motion Counter While Away
initial_state: 'on'
trigger:
platform: state
entity_id: binary_sensor.door_cam_motion
to: 'on'
condition:
condition: and
conditions:
- condition: state
entity_id: alarm_control_panel.ha_alarm
state: 'armed_away'
action:
- service: counter.increment
entity_id: counter.door_motion_away
- service: shell_command.pushover_glance
- alias: Front Door Motion Counter White Away Reset
initial_state: 'on'
trigger:
- platform: state
entity_id: alarm_control_panel.ha_alarm
from: 'armed_away'
- platform: time
at: '00:00:00'
action:
- service: counter.reset
entity_id: counter.door_motion_away
- service: shell_command.pushover_glance
- alias: Letters Today Midnight Reset
initial_state: 'on'
trigger:
- platform: time
at: '00:00:00'
action:
- service: counter.reset
entity_id: counter.letters_today
- service: shell_command.pushover_glance
It could do with a tidy up, and I think I’ll end up changing things as I find more/less useful features but it’s been really handy the last weeks knowing who’s home, how much energy is being used (left the oven on this week and noticed high wattage on watch), how many doors/windows are open before I go to bed and peace of mind with alarm glance.
Hopefully someone will find it useful, adapt, improve, simplify 
Thanks again @jenslj for the inspiration and guide!
