We just added Hayward TriStar / EcoStar support over RS485.
Technically, 100m (330ft). That is the spec. Regarding PoE, some will depend on how much power (how many watts) the powered device (PD) needs.Sorry to hijack for a min. But while everyone is on a cat 6 chat. How far can Ethernet cable be run and still be effective for both POE and signal? I want to run an access point and a couple cameras on my new pier being built. Will be about 200-250 feet max from the switch to the pier. Is this too long of run? If it is are there amplifiers that can be installed to make it work or am I SOL? I could potentially wire in separate power if needed and just use cat 6-7 for signal. But less wires getting run the better IMO. Keeps it simple.

Anecdotally, the Pentair seems to have better longevity than the Hayward. Probably because it is overbuilt, so even at full load it's only being used to a fraction of its capability (my understanding is that the 3HP perm. magnet motor is in reality a 5HP peak motor. But if you don't plan to run the pump full-bore much, the Hayward is probably the better value. The Hayward is also slightly more energy efficient. This is likely due to 2 factors: (1) that Pentair being overbuilt and (2) the Hayward's electronics on idle seem to burn much less power than the Pentair's & I would assume that is a constant offset between the wattage on those 2 pumps.OK another pump question. In general, I think there's pretty good agreement the Pentair VS pump is the best one on the market. My design company has an arrangement with Hayward that gives me access to preferred pricing and warranty. What do you all think about the Tristar VS 950? It's 2.7 hp and has built in RS 485 control plus digital input (with 3 inputs all standard 18-30 vac or 9-30dc) for control of up to 8 speeds. This is pretty big for me since I prefer to use one of the "build your own" control systems and I really don't want to mess with protocol interfaces.

ok awesome. I should be well under 330. I have a Switch that is far overkill for my application. (POE is 8 cameras and 5 access points including the new stuff). It has 16 POE+ and 8 POE++ so I will be safe and plug those long runs into the ++ ports to make sure they get proper power. I appreciate the info.Technically, 100m (330ft). That is the spec. Regarding PoE, some will depend on how much power (how many watts) the powered device (PD) needs.
Standard PoE (802.3af) is designed for a maximum delivered power of 12.95W to a powered device. That accounts for losses in the cable at max length, as the power sourcing equipment (PSE)...your switch or inserter, can output up to 15.4W @ 57Volts and the PD can operate between 37-57V.
If you need more power then that, PoE+ (802.3at) can deliver 25.5W at the PD. There are newer standards in work to deliver more, but PoE and PoE+ are your best bet for commonly available equipment.
Check the maximum power output of the switch.ok awesome. I should be well under 330. I have a Switch that is far overkill for my application.

good catch, 400 watts max it says. I presume thats across all 21 ports. I have the Ubiquiti switch pro 24 poe. 7 Cameras are 12.5W each and 1 big pan and zoom camera is 42.5W. Access points are 16.5W. So I should only be a little over half its capacity. So room for expansion In the future.Check the maximum power output of the switch.
Many switches have 8 or 16 PoE or PoE+ ports, but will have a maximum power capacity that is insufficient to power everything at max simultaneously.
So you need to add up the consumption of all the PDs that will be powered from that switch and make sure the switch can support that +15%.
For example, 8 ports of PoE running full-load (12.95W ea.) = 103.6 (call it 104) watts. +15% gives 120W. Technically, the PSE (switch) needs to do 8x 15.4 = 123.2 watts, but that's where my 15% rule-of-thumb comes from...close enough.
You will find that a lot of 8-port PoE switches only can source 60 or 80 watts. So if you have a lot of low-power devices that are like 5 watts, then you're good as you stay within the budget of the switch. Just remember that just because it says it has 8 PoE ports doesn't mean it can support 247 watts output. Nor do you typically need it to.
Time to run fiber.TLDR Version of Dirk’s post - his house has more copper built into than the US Mint on penny stamping day ….
Until you have to screw something to the wall....Hey, I absolutely love both. Having dealt with redwood siding, T-111, cedar shingles, asphalt shingles and worse all my life, I absolutely love my concrete exterior. It'll last longer than me, probably will never need repair or paint, and from inside my house, looks exactly like any other exterior I've ever lived in!![]()
Do you want to tell the non desert people what a riparian area is?There is a road nearby that runs across a wash (dry River bed for you non-desert rats). It’s the lowest point in the area.
I've done it plenty. Concrete drill and any of these types of anchors. It's not as easy as wood, of course, but it's no biggie.Until you have to screw something to the wall....
BTW. Who says stucco does not need to be painted? This guy with a CBS house just had his whole outside repainted. I anticipate the paint to probably last about 15 or so years, but you do need to repaint.
Why? My color is in the stucco. 11 years and it still looks new! It might get dingy, but I am hoping a pressure wash will restore it well enough, should the need arise. And so far, it hasn't.BTW.

That sounds possible. But I suspect my post-tension slab will have a hand in minimizing cracks. And my windows aren't caulked. We'll see.Every house exterior needs maintenance.
After about 15 years I had my stucco finish recoated to seal spider cracks and all of the windows recaulked.
You can pay now and keep the house shell weatherproof or pay later with rot and mold repairs.
