plant - control the position of an internet-connected plant¶
This plugin interfaces to a Iotsa MotorServer board. This board is a esp8266-based small REST-like web server that controls a stepper motor, thereby allowing the physicl position of something in the house to be controlled over the internet.
The MotorServer repository https://github.com/cwi-dis/iotsaMotorServer contains the source code for the server, as well as schematics and 3D-models of the hardware needed.
schema¶
environment/energy/electricity
: float, current electricity consumption in kW. Stored here by a plugin like smartmeter_iotsa.devices/plant/target
: float, wanted cable length in millimeters.devices/plant/pos
: float (read-only), current cable length in millimeters.devices/plant/speed
: float (read-only), current motor speed.devices/plant/inrange
: integer (read-only), nonzero if the cable is at an ultimate position, as indicated by the end stop microswitches.
actions¶
- every minute the current position (and speed, etc) of the plant is retrieved and stored in
devices/plant
. - Whenever
environment/energy/electricity
changes and ifenvironment/night
is falsedevices/plant/target
is updated. This action contains the formula to convert kW (unit of electricity use) to cm (unit of plant height). - Whenever
devices/plant/target
changes this change is forwarded to the MotorServer.
