Such works are still in their early stages either by lack of access to data or, on the other hand, by the lack of simple test cases with a clear added value. This contribution aims at shading some light on how knowledge can be obtained, using a simple use case. It focuses on the feasibility of having a home refrigerator performing temperature forecasts, using information provided by both internal and external sensors. The problem is reviewed for both its potential applications and to compare the use of different algorithms, from simple linear correlations to ARIMA models. We analyse the precision and computational cost using real data from a refrigerator. Results indicate that small average errors, down to \u22480.09      \u2218    C, can be obtained. Lastly, it is devised how can the scenario be improved, and, most importantly, how this work can be extended in the future.<\/jats:p>","DOI":"10.3390\/s18113610","type":"journal-article","created":{"date-parts":[[2018,10,24]],"date-time":"2018-10-24T10:40:48Z","timestamp":1540377648000},"page":"3610","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Indoor Temperature Prediction in an IoT Scenario"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6041-2259","authenticated-orcid":false,"given":"Pedro","family":"Monteiro","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Faculty of Science and Technology, Universidade Nova de Lisboa, 2829-516 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5839-0393","authenticated-orcid":false,"given":"Massimiliano","family":"Zanin","sequence":"additional","affiliation":[{"name":"Centro de Tecnolog\u00edas Biom\u00e9dicas, Universidad Polit\u00e9cnica de Madrid, 28223 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ernestina","family":"Menasalvas Ruiz","sequence":"additional","affiliation":[{"name":"Centro de Tecnolog\u00edas Biom\u00e9dicas, Universidad Polit\u00e9cnica de Madrid, 28223 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6011-008X","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Piment\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Faculty of Science and Technology, Universidade Nova de Lisboa, 2829-516 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Alexandre da Costa Sousa","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Faculty of Science and Technology, Universidade Nova de Lisboa, 2829-516 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1108\/IntR-06-2015-0183","article-title":"Introduction: Advances in IoT research and applications","volume":"26","author":"Wang","year":"2016","journal-title":"Internet Res."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Gravina, R., Palau, C.E., Manso, M., Liotta, A., and Fortino, G.
