As temperatures climb, your home shifts from heating mode to cooling mode. Energy usage patterns change, devices run longer, and power bills creep up. Spring is the right time to tune your systems before the heat arrives and everything is running at full load. The projects I’ll cover below are about tightening up the systems you already rely on so they perform efficiently and predictably through summer.
Here are the home energy automation projects I recommend tackling before summer hits.

Smart Thermostat Optimization Before Cooling Season
If you already have a smart thermostat, this is the moment to revisit how it’s configured.
I run an ecobee3 lite, which I installed and reviewed in my ecobee3 lite smart thermostat install and review. It’s integrated into Home Assistant, which gives me visibility and control beyond the stock app.
Even without complex automations tied to weather or time-of-use pricing, simple scheduling changes make a measurable difference. In our house, the thermostat reduces heating while we’re sleeping. The same principle applies to cooling. Decide what temperatures actually make sense overnight and during work hours. A few degrees over a long cooling season adds up.
Before summer, verify:
- Fan settings (continuous vs auto)
- Minimum compressor off times
- Temperature calibration
- Sensor placement accuracy
If you’re using remote sensors, confirm they reflect how rooms are actually used in summer. A bedroom that felt fine in winter might trap heat in July.
If you’re considering upgrading your thermostat, our Smart Thermostat Advisor walks through wiring requirements, HVAC compatibility, and integration preferences so you don’t guess.
Smart Plugs as Energy Diagnostic Tools
Smart plugs are often treated as basic on/off switches. In practice, they’re some of the most useful diagnostic tools in a smart home.
Used properly, they help you:
- Identify phantom loads
- Measure real-world device consumption
- Confirm equipment health
- Automate high-draw devices
- Detect abnormal behavior early
Before summer, I recommend adding energy-monitoring smart plugs to:
- Portable air conditioners
- Dehumidifiers
- Fans
- Garage refrigerators
- Sump pumps
- Network racks
Summer is when intermittent loads become steady loads. A dehumidifier pulling 600 watts for hours a day can greatly affect your monthly bill. A failing sump pump may show unusual power draw before it fails entirely.
Smart plugs also allow conditional automation. For example:
- Alert if a sump pump hasn’t drawn power in 48 hours.
- Track portable AC runtime to estimate operating cost.
- Shut down non-essential loads during peak hours.
- Confirm that a device actually turned on when scheduled.
If you’re unsure which plugs offer reliable energy monitoring and integration support, our Smart Plug Advisor narrows options based on your ecosystem and desired features.
Whole-Home Power Monitoring
If you want to go deeper, whole-home monitoring changes how you think about energy entirely.
In Track Home Power Usage & Cost with Home Assistant, I walk through how I set up panel-level tracking and cost dashboards inside Home Assistant. It’s an older article, but the core idea remains important: once you see real-time wattage and cost overlays, you stop making decisions based on assumptions.
Before summer, establish a baseline:
- What is your average idle load?
- What does your home draw overnight?
- What is HVAC startup load?
- How much does cooling add to daily usage?
When cooling season begins, you’ll see exactly how much additional load your system introduces. That clarity informs thermostat tweaks, automation adjustments, and even appliance replacement decisions. Even partial monitoring through smart plugs improves decision-making. Panel-level monitoring is icing on the cake.
Leak Detection Before Travel Season
Summer often means travel, and empty homes and plumbing failures don’t mix well.
I use the Meross MS400 smart leak sensor, which I reviewed in my Meross MS400 smart leak sensor review. It’s inexpensive insurance.
Before summer, place leak sensors under:
- Water heaters
- Washing machines
- Kitchen sinks
- Bathroom vanities
- Near sump pits
Integrated into Home Assistant, leak detection becomes more than a push notification. You can trigger:
- Immediate phone alerts
- Audible alarms
- Flashing lights
- Notifications to a secondary contact
You don’t need a full automatic shutoff valve to benefit. Early detection alone dramatically reduces damage.
Prepare for Summer Outages
In my area, most outages happen in the fall and winter, but they can happen in the summer too. Grids are often taxed by A/C units, which can lead to blackouts and brownouts in some areas.
Before summer:
- Test UPS batteries.
- Confirm runtime under load.
- Replace aging batteries.
- Simulate a short outage to confirm network equipment restarts cleanly.
In Preparing Your Smart Home for Outages, I outline a practical checklist for maintaining smart home functionality during disruptions. If you rely on internet connectivity for work, security monitoring, or automation, verify your failover plan. If you have cellular backup internet, test it intentionally.
A Quick Summer Energy Automation Checklist
Thermostat
- Review cooling schedule.

- Verify temperature calibration.
- Test integration with Home Assistant.
Smart Plugs
- Identify high-draw summer devices.
- Monitor phantom loads.
- Create runtime alerts for critical equipment.
Power Monitoring
- Establish baseline idle load.
- Track HVAC startup consumption.
- Review cost dashboards weekly.
Leak Detection
- Place sensors under major plumbing fixtures.
- Confirm alert delivery.
- Check battery levels.
Outage Readiness
- Test UPS runtime.
- Simulate internet failover.
- Confirm automation restarts properly after power restoration.
Final Thoughts
Energy automation needs periodic attention. Small adjustments compound across a cooling season.
And stepping back for a moment, this is the same principle behind Life by Design. Systems reduce friction. When your home operates intentionally, you spend less time reacting and more time focusing on what matters. Energy efficiency, reliability, and clarity all reinforce each other.
Take an hour or two before summer heat arrives and tune the systems. You’ll notice the difference — both in performance and in the bill.
