Alex's Corner - Week 5 - Sensors, Libraries and More!
-
@robmarkcole Yes 27th haha my mistake!
I'm actually working on something to publish regarding the RPi 3 and LoPy as a gateway
-
@bucknall OK great! I have a couple of projects that want LowRa to monitor various services on the estate I live on :-)
-
@robmarkcole This should fit the use case then!
The main idea is being able to set it up with just a quick install script using a product called Resin. It will run it's own Node-Red instance and also support it's own MQTT server so you can retrieve your LoRa messages via MQTT.
-
@bucknall sounds interesting! One thing that could help get started is to release a raspberry pi image (.iso) with everything configured and ready to go, this makes life very easy :-) e.g. https://home-assistant.io/docs/hassbian/installation/
-
Quick update - I'm postponing the community showcase as there were some people unable to join for the date which I outlined.
I still very much intend to run this showcase and will create a new post closer to the time.
In the mean time I will host another Alex's Corner explaining how to import libraries and re-writing MicroPython/Arduino Libraries to be compatible with the Pycom devices.
-
Apologies for the delay, we're starting a little bit late today due to some maintenance being done in our office! Will be starting at half past 2pm!

@bucknall
I have question about voltage.
I see on video (4 minute) that you connect 5V from expansion board to all devices
What about voltage on I2C pin then? -
@livius both the LCD and ADXL345 have 5 V to 3V3 regulators. I believe the LCD's backlight requires 5 V but it's data sheet isn't particularly clear!

@bucknall Any chance of Resin on the Wipy? https://resinos.io/ There is now a Home-assistant install using resin described here https://community.home-assistant.io/t/introducing-hass-io/17296
