"Failsafe" ESPHome Fireplace Controller

0 0 Intermediate
When asked what smart switch to use to control their gas fireplace, you see a lot of replies "do you want to be one software bug away from your fireplace turning on?" Granted, modern gas fireplaces have safeties in place to prevent un-lit open valves, runaway heating, etc., but some people would still rather have a hardware switch standing between them and fire. This project aims to be the best of both worlds: by running 5v power to the low-voltage switch box holding my fireplace wall switch (in my case, this involved pulling 5-conductor thermostat wire using the existing 2-conductor wire), you can power an ESP board running ESPHome. By running the actual thermostat switch signal through both a DPST and a (ESPHome-controlled) 3v relay, we can be sure that the fireplace is only "active" if the manual switch is turned on.

How additive manufacturing drives business model change: The perspective of logistics service providers

0 1 Beginner
Highlights • We structure the variety of LSPs' reactions to the threats and opportunities of AM. • Our approach combines a taxonomy and cluster analysis of 52 AM activities of LSPs. https://grabcasd.com/ • We explore how LSPs adapt their traditional business models to digital AM. • Propositions and the extensive overview of AM activities foster future research. Additive manufacturing (AM) is expected to facilitate local manufacturing in shorter, less complex supply chains and, thus, impact the demand for traditional logistics services. With increasing dissemination, AM confronts logistics service providers (LSPs) with the question of how they should adapt their business model to the threats and opportunities that come with the emerging digital technologies. We structure the AM activities of LSPs and develop a deep understanding of their resulting business model dynamics. For this exploratory purpose, this study develops a taxonomy and performs a cluster analysis to present six clusters of how LSPs approach AM today. The six profiles include LSPs that reactively monitor AM or, in contrast, proactively leverage AM for their internal operations and the development of new services for their external customers. Among them, four profiles entail fundamental changes to the traditional business models of LSPs. We find that these LSPs oftentimes continue to rely on their traditional “analog” service strengths to offer integrated service bundles of AM and logistics solutions. They bridge their lack of specific resources by strategic alliances with AM experts. Only a few LSPs have started severing ties to their traditional businesses to develop digitally dominated, platform-based AM services that require different resources. Overall, the comprehensive picture of AM activities enables us to contribute to the knowledge of how LSPs navigate in the digital age and to the nexus of business model dynamics and emerging technologies. We propose a set of propositions and support practitioners in analyzing and designing AM activities. Introduction From a supply chain perspective, the essential game-changer of additive manufacturing (AM) technologies lies in the digitalization of the manufacturing process. Parts are manufactured layer-by-layer directly from the digitally available product specification without product-dependent setup and tooling. This significantly reduces production setup time and upfront costs (Holmström
