Smoke & gas detectors
'am looking for sensors to go with HA, and Googling brings up far more
makes & models than I'd expected ... with prices anywhere from below
5GPB to over 90GPB ... some battery, some mains, some both, some
low-voltage, some smoke & gas in one ... etc. I need some that work
well & reliably & offer zero-volts ralay contacts & look good
or at
least acceptable. Can anyone recommend particuar ones, please - 90GBP
seems OTT to me, and 5GBP seems NVM !
