The most recent release is ioBroker 2026-10-29, published yesterday. openHAB publishes no tagged releases, which costs up to 25 of the 100 points. LHA scores under 40, so check recent activity before adopting it. By stack, Nodejs (5), Java (3) and C (2) are the most common. Home Assistant, Node RED, EMQX and 8 more are permissively licensed; Domoticz, FMD Server, SOLECTRUS and 6 more are copyleft. FHEM is not hosted on a forge Repoly can read, so it has no measured score yet.
