You might have heard about The Things Network (TTN from now on) here or somewhere else. If you have not, then it's a good opportunity to visit the project and check if there is a community of users around you. I have been a core member of the TTN Catalunya community for over 2 years now. This year we are working hard deploying several new gateways in Barcelona and doing workshops and hackathons with the main goal of helping individuals and social entities to carry out projects around a LoRaWan open, libre (free as in freedom) and neutral telemetry network....

Sorry for the tongue twister ;) I've been somewhat busy lately and it's been a long time since my last post. I have a few projects on the go but not much time to sit down and write about them… Let's see if this one goes through… I've been lately looking for a reliable UPS system for Raspberry Pi 3. I moved my home server to a RPi a few months ago and even thou its behind an ACS UPS a couple of other projects involving RPis required mobility (one of them) and unassisted power backup (the other)....

Tindie is a great place to find uncommon electronic components or weird/interesting boards. I use to stroll around it's products to basically see what's new. It's like Kickstarted but for real. One such uncommon and new electronic components is the Panasonic's Grid_EYE AMG88 [datasheet, pdf] infrared sensor. And I first learn about it through Peasky Products breakout board at Tindie. And if you have been reading me lately you might know I'm going through my own LED fever....

If you have read me, you might know I have a firmware for ESP8266-based smart switches called ESPurna. The firmware integrates with Alexa, Domoticz, Home Assistant and about any other service that supports MQTT or HTTP REST APIs. It supports a variety of devices, including almost the whole Sonoff family by Itead Studio, but also some other commercially available boards and light bulbs, and open source hardware projects as well....

Moving from the ESP8266 world I've been diving lately I still love the simplicity of battery powered Moteino nodes. You might know I'm migrating my XBee-based sensor network at home to an RFM69 one. So long I have changed my door monitor and my weather station. They are sensing and reporting to my RFM69GW, an ESP8266 bridge board using a custom firmware. Time to go for the power monitor. A long time ago (actually 2 years but it really feels like a century ago) I was living in a big city and we had one of those fancy “smart meters” with a LED pulsing 4000 times every kWh....
