i’ve had 8 of the ws0002 sensors running at one pimatic instance with massive problems regarding RF interference.
I reduced to 4 sensors now, runnig very stable. but I guess 4 to 5 sensors sending all 30 sec. is the limit for having a stable system without any trouble of interfering.
what’s your price limit?
as sweebee said, you should think of either the mysensors or build yourself with attiny and ds18b20 sensors and rf sender. i read about the short battery life (appr. 1 week) with the arduino mini and ds18b20 at the mysensors forum…
maybe there’s another solution. anybody else with an good idea?!
sure, it’s some kind of work but if you have build one or two it’s going fast
