Recently I bought my first house, and that means no more silly tenancy agreement rules, e.g. no picture hooks on the walls or screwing with the wiring, aka ultimate smart home freedom :-D. To complement my CurrentCost SDR logging and Temperature & Humidity sensors I decided it was time to buy a cheap hackable doorbell, the
A few posts ago I wrote a simple guide on how to read power usage stats from CurrentCost CT Clamps using Software Defined Radio, you can check it out here. This is great but how can I view historic power consumption or integrate this data with other stuff? First we need somewhere to store the data
Following on from my LoRa temperature and humidity sensor and CurrentCost SDR man in the middle it became apparent a time series database was needed to store all the data that was being collected. RRDTool seemed the obvious choice and although it has a good track recorded at dealing with time series data previous interactions
As you have probably guessed from my previous blog posts I am slowly pimping (or in the words of the misses, making a mess) my house with a variety of Internet of Things devices such as Phillips Hue, various sensors and so on. After discussing IoT devices with my work colleague the other day he
A few weeks ago I decided I’d like to compare the results of Radio Mobile Online and my actual LoRa coverage using TTNMapper, and although I have not walked all roads within the coverage prediction I have walked the roads around my house and the results are quite underwhelming so far. Here is a very
Out of curiosity I have been trying to establish the range in which my LoRa gateway can receive packets, first off I started using the tools by Radio Mobile Online which allows you to determine coverage estimates based on the antenna positioning details and the height profile of the area around your antenna, you can
Recently I have been working on a project to provide a File Intelligence API within the OpenStack ecosystem (OpenStack Nemesis) which can be used to find out information about a given file based on it’s hashes, the plan is to support multiple pluggable backends for processing files which are unknown to the system and provide
Continuing with my mission to convert my ESP8266 based sensors into LoRaWAN enabled sensors I pushed on with getting a DHT22 on breadboard and getting the code written to submit temperature and humidity over LoRa. If you’d like to replicate this mini project you’ll need the following: Arduino Uno or equivalent SX1272 / SX1276 LoRa
Another LoRa transceiver module finally arrived from China today, now I have two of the things I decided to crack on with building a LoRa push button using an Arduino Uno and the LoRa module. Eventually this will be developed into a small circuit on strip board consisting of the LoRa module, an ATMega328-PU and a
Wohoo, whilst taking a look over the logs today, although I have no LoRa nodes myself, I noticed that my Single Channel LoRa Gateway had received it’s first packet from somebody and here it is… stat update: {“stat”:{“time”:”2017-05-08 22:00:49 GMT”,”lati”:0.00000,”long”:0.00000,”alti”:0,”rxnb”:0,”rxok”:0,”rxfw”:0,”ackr”:0.0,”dwnb”:0,”txnb”:0,”pfrm”:”Single Channel Gateway”,”mail”:””,”desc”:””}} Packet RSSI: -113, RSSI: -112, SNR: -11, Length: 9 rxpk update: {“rxpk”:[{“tmst”:1621788918,”chan”:0,”rfch”:0,”freq”:868.100000,”stat”:1,”modu”:”LORA”,”datr”:”SF7BW125″,”codr”:”4/5″,”lsnr”:-11,”rssi”:-113,”size”:9,”data”:”xoT77qK24c5x”}]} stat
