GOTO Nights are thrilled to collaborate with Reactive Amsterdam for this event.

IoT is a prime use case for the Reactive principles. With so many connected devices, scalability and resilience need to be built in the system from day one. Join Johan Stokking, Co-founder of The Things Network, as he shows us how they achieve these goals.

Talk #1: Going Industrial with LoRaWAN
Low-Power Wide Area Networks such as LoRaWAN and NB-IoT seem the perfect fit for IoT devices, combining low power consumption and kilometers of range. However, they come with constraints, bandwidth is limited and communication is uplink focused. This talk, by the CTO of the largest world-wide LoRaWAN network, covers the challenges and opportunities of using LPWAN networks for industrial use cases: focusing on reliability and deployments that will last.

Speaker bio: Johan Stokking
Tech Lead and co-founder of The Things Network, an open, crowd sourced and decentralized IoT network. Starting with covering the city of Amsterdam in less than six weeks, the community counts more than 46K developers in 97 countries and 4500 gateways connected: the biggest global LoRaWAN network. As CTO of The Things Industries, Johan oversees architecture, product development, operations and is involved in technical business development and customer engagement.

**Johan will be delivering his talk "Building LPWAN solutions that last for years" at GOTO Berlin on November 1: **

Talk #2: Outsmart your smart meter with Akka
Starting 2014, all Dutch households are receiving a "smart meter" to replace their old meter systems for electricity and gas. They're called "smart", but are they really? Most meters just send their data to a central point using GPRS. Using third party services, consumers can get an insight in their energy usage. But we're technicians, we can build something better ourselves. All it takes is a prefab cable (or some soldering), code, patience and a beer. Using Scala plus Akka for the backend, TypeScript plus React for the frontend and Websockets for communication you can build your own energy dashboard. En passant, we might even see a little Akka stream dropping by. Attend this session to discover how to outsmart your Smart Meter!
