How I Made My Heating Smart without Damaging or Replacing Anything

Smart Heating

Andy Bradford has been wanting to upgrade their home’s heating system for a some time – but their house is rented. Damaging the house would cause them to lose their security deposit, “so the whole system must do no damage, be made only of removable parts and be installed without modifying any of the existing infrastructure.” - AndyBradford.dev

The Things Industries launches a Global Join Server to push secure LoRaWAN provisioning practices

TTN Global Join Server

The Things Industries announced the launch of a Global Join Server which allows activation of any LoRa network, anywhere in the world, as long as it uses LoRa standard interfaces. This new ecosystem’s role is to “store root keys, generate session keys, and send them securely to the network and application servers”. This new model replaces the need for manufacturers to generate secure keys. - Things Industries via LinkedIn Pulse

Bluetera II, a full-stack dev board that uses protocol buffers

BlueTerra II

BlueTerra II is an open-source IoT development board which supports Google’s Protobuf and motion algorithms. This tiny board has “everything. From hardware to firmware to the software running on your mobile device or PC is strictly open-source”. They’re using a Madgwick-based motion fusion algorithm which is also open source, as opposed to other fusion algorithms supported by similar development boards. - CrowdSupply.
