i want to buy some smoke detectors for my house. Is there any smoke detector, which is cheap and works with openhab (wireless)?
KNX-Smoke-detectors are rather expensive, z-wave detectors the same. There are many rf-smoke detectors out there, is there anyone working with openhab? Are they connected with 433Mhz or 868 Mhz and can i connect to them with CUL or rfxcom or something like that?
Are there also smoke detectors which include temperature (and humidity) sensors?
