Who does not know this: you want to quickly build the hardware for a new project and then start long hours with the breadboard or soldering on a proto board. With newer sensors one still needs breakout boards, since the connections are not directly solderable. Many have written to me if there is not an alternative that works faster and delivers safer results. Yes, there is one: Seeed-Studio's GROVE system. I introduce you to a quick weather setup with GROVE for a small weather station. |

My underfloor heating (hot water) was previously controlled with Busch-Jäger bimetal thermostats. That went well, but there was no option for night setback or absence mode. As a SmartHome freak, I want to control everything from a tablet. Several experiments with finished electronic thermostats followed, with MAX! and HomeMatic, but nothing was really satisfying - sometimes very expensive. For a long time I have been using Shellies for the light switches in the house, which are connected via WiFi and fit into a flush-mounted box. These are inexpensive, reliable and can be integrated into OpenHAB via MQTT. I do not use the Shelly HT because it is a standalone device with battery operation and therefore only very rarely sends temperature updates to OpenHAB. Since Allterco has offered a temperature sensor add-on for the Shelly 1, I've toyed with the idea of using this duo for the thermostat. |
