- | ===== Telemetry Aggregator | + | The telemetry and sensing functions include: |
+ | |||
+ | * HVAC run monitoring: current measurement to determine when compressor and air handler are running, detect conditions where they are running too long, too often or out of sync. | ||
+ | * HVAC temperature monitoring: measure temperature output at one or more vents, compare to ambient temperature and outside temperature, | ||
+ | * HVAC air flow: trend air flow velocity to detect when filters need to be changed | ||
+ | * Appliance current monitoring to detect usage: especially for EV chargers to determine use patterns and estimate costs. Monitoring hot water heater can detect trending that may indicate problems. Can also detect burned out bulbs by correlating a switch that is on with low current draw. | ||
+ | * Ambient temperature and humidity: detect trends that may lead to problems due to high humidity in certain rooms or crawl space. Can also warn of freezing temperatures which may lead to problems. | ||
+ | * Pool water level: detect water level drops that may create operational problems | ||
+ | * Pool water temperature | ||
+ | * AC mains availability: | ||
+ | * Water flow measure: detect system leaks, faucets left open | ||
+ | * Water leak detector: detect presence of water to detect leaks | ||

- | ===== House Gateway Node ===== | + | ==== House Gateway Node ==== |
- | The house gateway node provides the link between data collection nodes and the telemetry aggregator. | + | |
- | ===== Data Collection Nodes ===== | + | The gateway node is responsible for: |
+ | |||
+ | * Collecting data from data collection nodes and forwarding to the telemetry aggregator | ||
+ | * Wifi network for data collection nodes | ||
+ | * Scheduling sensor readings | ||
+ | * Managing configuration settings for local devices | ||
+ | * Provides link to the internet via cellular or routing through on-site network | ||
+ | * System monitoring and management | ||
+ | * Some telemetry collection where appropriate - so it may serve as a data collection node as well as a gateway | ||
+ | |||
+ | The Gateway node hosts a wifi network that uses credentials to join - this is the only security for the link between the gateway and data collectors. | ||
