I’ve already been plugging in data from my Emporia Vue, which reads the meter from Southern California Edison and allows me to query my usage in kW/h from Home Assistant. I now need to calculate cost, which is variable based on what SCE calls TOU (Time Of Use). This essentially means peak hours (typically 4PM - 9PM) have higher rates than off-peak. I broke this problem down into 3 entities to solve: TOU Season (Summer vs Winter) TOU Peak (Current hourly block) TOU Cost ($ per kW/h) I can use Cost as the dynamic entity in our Energy Usage dashboard. This, combined with the kW/h reading, can be used to calculate total energy costs per day. This defines the 3 entities in my sce.yaml. If you’re copying this, plug your peak costs into the last few lines of this snippet. You can find updated rates here: https://www.sce.com/residential/rates/Time-Of-Use-Residential-Rate-Plans template: - sensor: - name: "TOU Season" state: "{{ ['Winter', 'Summer'][now().month >= 6 and now().month < 10] }}" icon: mdi:weather-cloudy-clock - sensor: - name: "TOU Peak" icon: mdi:calendar-clock state: > {% set is_weekend = now().strftime("%w") == 0 or now().strftime("%w") == 6 %} {% if states('sensor.tou_season') == "Summer" %} {% if now().hour >= 16 and now().hour < 21 %} {% if is_weekend %} {{ "Mid-Peak" }} {% else %} {{ "On-Peak" }} {% endif %} {% else %} {{ "Off-Peak" }} {% endif %} {% else %} {% if now().hour >= 16 and now().hour < 21 %} {{ "Mid-Peak" }} {% elif now().hour >= 21 or now().hour < 8 %} {{ "Off-Peak" }} {% else %} {{ "Super Off-Peak" }} {% endif %} {% endif %} - sensor: - name: "TOU Cost" icon: mdi:currency-usd device_class: monetary state: > {% if states('sensor.tou_season') == "Summer" %} {{ {"Off-Peak": 0.15, "On-Peak": 0.41, "Mid-Peak": 0.30}[states('sensor.tou_peak')] }} {% else %} {{ {"Super Off-Peak": 0.15, "Off-Peak": 0.15, "Mid-Peak": 0.38}[states('sensor.tou_peak')] }} {% endif %} Updated values for Option 1 TOUD-5-8PM: template: - sensor: - name: "TOU Season" state: "{{ ['Winter', 'Summer'][now().month >= 6 and now().month < 10] }}" icon: mdi:weather-cloudy-clock - sensor: - name: "TOU Peak" icon: mdi:calendar-clock state: > {% set is_weekend = now().strftime("%w") == 0 or now().strftime("%w") == 6 %} {% if states('sensor.tou_season') == "Summer" %} {% if now().hour >= 17 and now().hour < 20 %} {% if is_weekend %} {{ "Mid-Peak" }} {% else %} {{ "On-Peak" }} {% endif %} {% else %} {{ "Off-Peak" }} {% endif %} {% else %} {% if now().hour >= 17 and now().hour < 20 %} {{ "Mid-Peak" }} {% elif now().hour >= 20 or now().hour < 8 %} {{ "Off-Peak" }} {% else %} {{ "Super Off-Peak" }} {% endif %} {% endif %} - sensor: - name: "TOU Cost" icon: mdi:currency-usd device_class: monetary state: > {% if states('sensor.tou_season') == "Summer" %} {{ {"Off-Peak": 0.33, "On-Peak": 0.67, "Mid-Peak": 0.50}[states('sensor.tou_peak')] }} {% else %} {{ {"Super Off-Peak": 0.32, "Off-Peak": 0.36, "Mid-Peak": 0.55}[states('sensor.tou_peak')] }} {% endif %}

Home Assistant only creates sensors for VM states, and does not yet provide a way to control those VMs. If you want to simply shutdown/startup a VM from Home Assistant, the rest_command is your friend.

A Ulauncher extension to view and control devices in your Home Assistant instance.

The Home Assistant Kodi Integration is nice, but as of writing it becomes slower the longer Home Assistant runs. This sucks, especially when automations (like turning on a power hungry receiver) don't run because of it.
