Google API directions extractor. I have a need to export Google turn directions into a structured format so that they can be presented as printouts. Google Python reference is here: https://googlemaps.github.io/google-maps-services-python/docs/. Google's github for the python lib - https://github.com/googlemaps/google-maps-services-python which …

nickbalch / Moteino-Python-MQTT Bridge.md

Last active August 21, 2018 14:39

Moteino-Python-MQTT Bridge. Assumes a connected (via USB) moteino, and supports a number of specific formats for the data received. Refer to the arduino files where I have shared versions that use external temp sensors, or motion detectors. I relied very heavily on the sample sketches provided for the Moteinos plus code written by Gareth Naylor - …

These are samples of my moteino to MQTT solution. Various moteino nodes send data to a central moteino node (Gateway) that is connected to a RaspberryPI via USB This Pi runs a python program that parses the recieved data and sends to various MQTT topics Other systems subscribe to the MQTT topics (for example, Openhab)

Moteinos are battery operated, run for many months on a 9V cell

Openhab presence rules for a living area and office. Takes input from PIRs, records presence, and turns on / off lights

	rule "Working from home"
	when
	Item Presence_HomeOffice received command ON or
	Item Presence_Living received command OFF
	then
	if (Presence_HomeOffice.state == ON && SCENE_LateNight.state != ON && Presence_Living.state != ON && GF_Living_Lights.state != OFF && SCENE_Watching.state != ON && SCENE_Evening.state != ON) {
	// if only home office is occupied, turn off lights //
	sendCommand(ALL_GF_LIGHTS,OFF)
	}
	end

nickbalch / moteino.items

Last active June 20, 2016 09:27

Moteino items and rules for Openhab. An MQTT broker is used to send data from the nodes. Openhab subscribes to the broker and picks up the updates. Nodes are configured to send data every 15 minutes. For ease of configuration and transparency, I have chosed to use a rule to map the nodes 1-5 to specific items. Moteinos are very mobile, so if one…

	Group Moteino (State)
	Group Moteino_batt (Moteino,Battery)
	Group Moteino_temp (Temperature)
	Group Moteino_signal (Moteino)
	Group Moteino_monitor (Moteino,Status)
	Group Moteino_version
