I want control some pool valves in Homeseer. I am aware that the draw is about .75 amps. That pretty much makes it so I have to use a Relay 8 with some 24 volt transformers. I do have more then 8 zones though. I checked with WGL and you cannot daisy chain a relay 8. Does anyone know if I can run 2 Relay8's on different com ports (or UPB based).

Seems like there should be other hardware interfaces other than Relay8 that can hanlde the amperage so it could be done with a single interface. I do not have any specific suggestions.

We use two of these for our pool, with relays for the pumps and valves. There is also two analog in which we use to get the temp of the pool. This has been stable so far.

"Sorry to say but the Relay8net only works as a standalone module. No expansion, no adding on to a Rain8net. It will have to be connected to its own com port.

I was wishful to avoid a new technology in my mix, but ultimately it may be the best answer and avoids me running a serial cable out there. What kind of pump are you running? If Insteon (which I have never messed with) how is the latency and which PLM are you using?
There is almost no delay between commands sent and the pumps reacting. We have 5 Jandy 240v pumps, 3- 24v three way valves, 2- 120v light systems, 24v control for the heater, 24v auto fill valve, 2 analog temp sensors. Everything is wired through standard Din rail components.
If I was building it new, I would consider a Raspberry Pi instead of the Insteon devices.

What I have done in the past is to use a UPB IO module to provide the interface that controls an independent relay(s). Same could be done with Appliance Module if you want to use a relay with 120V coil. A relay from Radio Shack or anywhere online will satisfy your need. If I remember the UPB IO module has two discrete outputs. Zwave should have a similiar unit if you are in Zwave range.

Thanks guys for all the suggestions. I will piece something together here. I am going to build it with UPB though and 2 Relay 8's. I found this cool little power supply to drive the relays. Should be able to run lots of channels on at same time if needed.
