About This Project
This project is a control platform for my solar panels and power inverter. Goal is to monitor transformer and heatsink Tempuratures then take action by energizing the cooling fan in the power inverter and the windmill dumpload heatsinks.
(general introduction, overall experience with Cayenne, why did you create this project??)
I created this project out of a need to automate certain functions of the solar energy system. Since the algorithm used to monitor temps and control the inverter fan has been known to be flaky, I decided it was best to use Rpi3 and Cayenne. I have incorporated dumpload resistors on heatsinks to brake the windmill in high winds when the batteries are fully charged and these need cooling fans activated by Tempurature. This system will be installed in the Philippines and I can monitor it from the US.
(Hardware, sensors, actuators, device model, WiFi, etc.)
Rpi3 Model B
8 relay actuator board for control functions
12" touchscreen for local browser use
6 ds18b20 stainless waterproof sensors
1 TSL2561 lux sensor
1 MCP3208 ADC for monitoring voltages thru the use of voltage dividers(True readings will come when voltage scaling is incorporated in Cayenne)
Triggers & Alerts
(Did you use the Triggers & Alerts feature?)
I used triggers to activate the cooling fans at certain temperature thresholds. Trigger on above certain temp then trigger off below certain temp.
Set a trigger to notify me when Rpi is offline and online.
(Did you use the Scheduling feature?)
I have a schedule set for sun up and sun down for off grid solar energy during the day, hope to use the lux sensor to do this without a schedule. I can also press a widget button on dashboard to manually reset inverter if it goes into alarm as well as 3 other buttons to control cooling fans manually. Will add later a widget to notify alarm status of battery bank monitoring system.
I will add more pics after this is installed on my solar energy system in the Philippines this coming January.
Enjoy The View!
