About
Small-batch Home Assistant hardware, designed and built in Ireland.
SolBus makes interface boards that bring heating and solar controllers into Home Assistant via ESPHome — starting with Resol VBus (DeltaSol and its rebadges: Viessmann, COSMO, Caleffi, Sonnenkraft, Firebird and more). It began as a board I built to get my own solar system into Home Assistant.
• Honest about compatibility — message me with your controller model before ordering and I'll tell you straight whether it's supported. • Built on open source — with full credit to the original open-hardware projects. • Tested before shipping, posted from Ireland via An Post.
