Plugwise

- Improvement: Debounce relay state
- Improvement: Prioritize request so requests like switching a relay get send out before power measurement requests.
- Improvement: Dynamically change the refresh interval based on the actual discovered nodes with power measurement capabilities
- Added: New property attributes for USB-stick.
The old methods are still available but will give a deprecate warning
- Stick
- `devices` (dict) - All discovered and supported plugwise devices with the MAC address as their key
- `joined_nodes` (integer) - Total number of registered nodes at Plugwise Circle+
- `mac` (string) - The MAC address of the USB-Stick
- `network_state` (boolean) - The state (on-line/off-line) of the Plugwise network.
- `network_id` (integer) - The ID of the Plugwise network.
- `port` (string) - The port connection string
- All plugwise devices
- `available` (boolean) - The current network availability state of the device
- `battery_powered` (boolean) - Indicates if device is battery powered
- `features` (tuple) - List of supported attribute IDs
- `firmware_version` (string) - Firmware version device is running
- `hardware_model` (string) - Hardware model name
- `hardware_version` (string) - Hardware version of device
- `last_update` (datetime) - Date/time stamp of last received update from device
- `mac` (string) - MAC address of device
- `measures_power` (boolean) - Indicates if device supports power measurement
- `name` (string) - Name of device based om hardware model and MAC address
- `ping` (integer) - Network roundtrip time in milliseconds
- `rssi_in` (integer) - Inbound RSSI level in DBm
- `rssi_out` (integer) - Outbound RSSI level based on the received inbound RSSI level of the neighbor node in DBm
- Scan devices
- `motion` (boolean) - Current detection state of motion.
- Sense devices
- `humidity` (integer) - Last reported humidity value.
- `temperature` (integer) - Last reported temperature value.
- Circle/Circle+/Stealth devices
- `current_power_usage` (float) - Current power usage (Watts) during the last second
- `current_power_usage_8_sec` (float) - Current power usage (Watts) during the last 8 seconds
- `power_consumption_current_hour` (float) - Total power consumption (kWh) this running hour
- `power_consumption_previous_hour` (float) - Total power consumption (kWh) during the previous hour
- `power_consumption_today` (float) - Total power consumption (kWh) of today
- `power_consumption_yesterday` (float) - Total power consumption (kWh) during yesterday
- `power_production_current_hour` (float) - Total power production (kWh) this hour
- `relay_state` (boolean) - State of the output power relay. Setting this property will operate the relay
- Switch devices
- `switch` (boolean) - Last reported state of switch
- Stretch v2: fix failed connection by re-adding the aiohttp-workaround

- Bug-fix: Power history was not reported (0 value) during last week of the month
- Improvement: Validate message checksums
- Improvement: Do a single ping request to validate if node is on-line
- Improvement: Guard Scan sensitivity setting to medium
- Improvement: Move general module code of messages, nodes, connection to the **init**.py files.
- Improvement: Do proper timeout handling while sequence counter resets (once every 65532 messages)
- Improvement: Better code separation. All logic is in their designated files:
1. Connection (connection/\*.py)
2. Data parsing (parser.py)
3. Data encoding/decoding of message (messages/\*.py)
4. Message handling - Initialization & transportation (controller.py)
5. Message processing - Do the required stuff (stick.py & nodes/\*.py)
- Improvement: Resolves all flake8 comments

- Fix for HA Core issue 44349
- Fix other value scaling bugs
- Remove aiohttp-workaround - issue solved in aiohttp 3.7.1

- Switch Smile to defusedxml from lxml (improving security)
- Lint and flake recommendations fixed
- Project CI changes
- Bug-fix: fix use of major due to change of using semver.VersionInfo.
- Add model-info: to be used in Core to provide a more correct model-name for each device.
- Code improvements and increase in test-coverage.
