    Wireless Control and Systems Integrators

    Have you used EnOcean wireless devices? They are the battery free and get their power from the energy surrounding them.

    If you have used them I would like your feed back. If not would you like to know more?

    I have used the RIB relays that use EnOcean.

    Both sides of the link where battery free, as they required 110 or 24v

    Short story, I was not impressed.

    I have had extremely poor results with EnOcean room sensors.... with or without battery.

    I tried an EnOcean room sensor with and without battery and frankly it was a total waste of money.
    I'm not sure whose technology Trane uses but I have had amazing results with their wireless receivers and sensors, and at half the cost of the EnOcean product.

    Well majority says enocean sucks, but has anyone had any luck with Zigbee or something like it?

    I've had good luck with Honeywell's TR21/23WK modules. The only "trick" to using them is connecting the earth ground.

    Earth ground meaning for the receiver?

    Have not used much more than industrial WIFI gear in a few places. For comms we stick with wire, if need be we can bring in the I/O wireless to the module. I would be all ears if someone has used some sort of wireless MS/TP gear. I have a feeling that the latency would torch the network at all but the slowest bauds.
