Found a dht11 but had no way to run a cable from the living room to basement, so I decided to use my pi running pi hole for the sensor. I spent a whole day just getting the values into webCore, and now I need a virtual humidity sensor dth. I wish I had just got an esp8266 and used konnected…well I took the challenge anyway.
Left a test setup overnight and it seems to be reporting temp fine. Once per minute. No updates if no change, presuming that’s normal behavior.
One thing I don’t understand is why there’s a need for a high level relay. Low level ones seem cheaper and easier to find. I’ve ordered 2 high level ones for £10 which isn’t great value.
Haven’t quite got my head around this, but wouldn’t it be possible just to have a low level and use the ‘inverse’?

Could you please clarify a couple of things ?

I’m attempting to future-proof a little here. Kinda sick of samsung/smartthings pulling the plug on certain things or randomly ‘improving’ something which then kills functionality. I initially thought of using the st_anything software, but this won’t be supported once ‘classic’ is ended. This is partly why I started messing around with konnected - the new app integration. Anyhoo, I take it that if for whatever reason, you guys decided to pull the plug on the cloud service you have, then this is going to quit working. Could you please clarify if my understanding of this is correct? Also, I’m assuming the cloud service isn’t cheap to run, so you guys need to be making your money somewhere, which I’m guessing comes from selling hardware / kits. I’d actually be quite interested in paying for a subscription etc if that was an option as I obviously didn’t find the hardware to be very good value for money over here in the UK. Could you maybe expand a little? I’m sure there are plenty of people like me who can happily pay a few quid for the cheap DIY hardware and support via a paid app/cloud service?
-
Disappointed to find that I can’t seem to use my DS18b20’s with konnected. I’ve added some DHT22’s, which seem at first glance to be awesome (!), but I also use DS’s to monitor pool temp and can’t link them to the DIY module. Apparently they are compatible with the ‘old’ konnected software, but not the new? Is this correct? The info from the forums seems a little sketchy. If I actually need to add a bit more hardware to one of the NodeMCU’s and then I’m able to use the DS’s too, that would be awesome. Could you please clarify? Seems to be something to do with a 5v breakout board or something… or is it a no go regardless?
-
Is it possible to adjust the polling interval for the DHT22 to seconds rather than minutes? Purely for testing purposes - seems to only work as 1, 2, 3 minutes. Is this correct? Would also be cool to only report if there’s a change in temp of more than x. Could you also clarify whether it’s normal for the temp report to only happen IF there’s a change? I set up the test board last night and woke up to think it had failed as humidity was showing changes, but temp was not. I’m assuming that this is due to no temp change = no report, regardless of polling interval. If so, it would be useful if temp could be polled regardless every x minutes to check that it’s functional.
-
Seriously considering a jump to hubitat for the mission-critical aspects of the home. If I did this, would I already be able to use this hardware, with konnected, to see motion sensors, door sensors, DHT22’s and DS18b20s … tomorrow? Or would I be better off heading to st_anything instead ? If that makes sense.
Cheers all, it’s been a fantastic learning experience and I really do appreciate taking the time to explain something so complex to someone such as myself with a fairly basic level of understanding. Eager to hear some of your insights.

“Us guys” are just other customers. We don’t have any inside knowledge, we don’t make any decisions about SmartThings platform or products.
This forum was started a number of years ago so customers could help other customers And share ideas. It’s actually not an official support channel.
There are a few smartthings staff members who do post here from time to time. They will all be identified as “staff“ on their icon profiles.
But otherwise, we are all just either guessing or speaking from personal experience as customers. 
All of that said, the best educated guess is that Samsung doesn’t make any money from smartthings itself. Definitely not from selling the SmartThings branded hardware.
Smartthings is a little tiny sliver of a gigantic company. I said back at the time of the acquisition that it looked to me like Samsung wanted the name and the buzz for being a Home Automation forward company. But their real money still comes from selling $4,000 refrigerators and $6000 televisions.
Look at it this way: there have been over 100 million downloads of the new V3 smartthings app (which is required for those smart televisions and appliances); less than 86,000 people have ever joined this forum. (And only around 1 million ever downloaded the classic version of the app. The big numbers didn’t come until the new app was required for those televisions and appliances. )
Home automation Power users have never been their target market, and it’s pretty clear that they aren’t actually making profits from us.
(There is a competing theory held by some community members that Samsung intends to make a lot of money by somehow selling information about customers connected to their cloud. But I just don’t see how that makes sense financially. And if it did, I think they would’ve made sure smartthings worked with their smart watches all along, which it hasn’t. But what do I know? 
)
If you are ok with leaving d8 unused, then all pins other than d8 have a low option. Anyway, if you can even find any 3v low level relays for cheaper than me…

Then it will work.
I think this question was directed at Konnected? Konnected’s cloud service is actually pretty cheap to run. It’s built entirely on AWS, which is quite affordable but scales up as usage increases. The big investment is my time – not the actual dollar cost of the AWS bill.
At this time, Konnected’s cloud service is free and anybody can sign up and use it. We may, at some point in the future, add premium features for a fee, or require a subscription or fee for people who are using hardware that wasn’t purchased from Konnected. As of now though, I haven’t spent the time to build any billing features – so it’s 100% free.
DS18b20 is not supported yet in Konnected Cloud, but it will be. I can’t commit to when, because priorities are always shifting.
No, the minimum polling interval is 1 minute. You may be able to modify the firmware to change this (it’s open source).
Konnected reports at every polling interval, but my understanding is that SmartThings collapses identical measurements and does not show a state change if the measurement hasn’t changed.
Yes, all the hardware will work exactly the same. You’ll just have to re-setup the zones in Hubitat.

They already sell this in the form of the $50 DIY kit with 6 zones.
Oh please no…I will be back to writing custom integrations if that happens…or I will be forced to use the groovy integration, which requires the dying classic app
If your dsb18b20s have a 3.3v option, then you can use the old groovy integration to get the devices into smartthings…
No…might strain the nodemcu
Hubitat has a groovy integration that is independent of the konnected cloud. It supports dsb18b20s. See the Hubitat section of this:

Thanks all. All questions wonderfully answered. Ta! Looks like hubitat is going to be ultimately the way forward.
So I think that for now, I’ll hook the pool temps up to konnected old school (or even stanything), and plan on eventual swap to hubistat when either my current hub dies or I manage to find one at a decent price, whichever comes first.
If I wanted to hook up some kind of rain / moisture / flood sensor I take it that’s possible with konnected? And also, a luminosity sensor?
Or, am I better off playing with stanything as Im guessing that it’ll support more sensors?
Also, if I wanted to monitor a doorbell push I take it that I’d just hook it up to ground / zone?
Cheers again - I’m now quite happy adding motion sensors, door sensors, dht22s and relays. =)
@djh_wolf I’m switching to Hubitat too most probably… the dsb temp probes work in Hubitat…the Hubitat integration is still in groovy
Hi JD, I think you may have got the wrong end of the stick from me =)
I was indeed referring to “what if konnected pulled the cloud” - totally get that this is an enthusiasts forum, with a few staff members kicking about. Also totally get the point about this being a drop in the ocean, not many users, smartthings lack of making money from this (which is 100 % the reason why they’re trying to stop everyone hammering their servers with groovy code etc).

Ah, bollocks it. I’ve just ordered a hubitat.
I really can’t be arsed with the issues. I seriously doubt that smartthings in general are going to be particularly concerned about losing, well, everyone who participates in these forums to be honest. It’s not as if they’re making any cash from us, and in fact, our lack of presence is probably going to do their servers more good than harm.
The performance lately has been patchy for me and I think at the end of the day, even if I do continue to play with the smartthings v2 hub when the new app is the exclusive option, then I just want all my mission-critical on a system that’s not going to give any aggro.
So it’s half a goodbye from me to smartthings! And onto the hubitat forums.
=p
@djh_wolf same here…just waiting for a $25 eBay deal before I jump in
@djh_wolf Smartthings requires the cloud for smartthings. The first thing that theives do nowadays is cut the internet cable, so this is useless in that case. Hubitat will work perfectly without internet. I know that my router and soon to get hubitat wont have battery backup, but a power cable can’t be cut easily. A coaxial cable, on the other hand, can be cut with pliers!
The other advantage to hubitat is that their is no possible way konnected will be able to charge a subscription. I can and probably will block the device from the internet and let the hubitat be the only device let on the internet.
Yes, get a binary water sensor and wire it up. Set the zone to water leak sensor.
Stick to zigbee for that… there is no option for such a sensor in konnected. If you have a pi for other things, I can slightly modify my pi dth11 smartthings and hubitat integration to work with light sensors if I can find a light sensor dth or code one.

@heythisisnate
Just wanted to revisit this thread and extend a huge THANK YOU for all the help and info.
I have now transitioned almost fully to hubitat, and would never have been so excited to re-do a lot of old projects (far better!) if it hadn’t been for this thread.
Bonus points for this coming along at the same time as St becoming so crippled.
To be fair, I think that if konnected (cloud) had supported my ds18b20’s then I may never have started investigating the other system.
Now.
Wow.
Door sensors, proper 12v motion sensors, humidity, temperature, garage door openers, relays… Trvs… The list goes on.
Very, very excited to be working on this new system and I owe it all to this thread. And the nodemcu / konnected.
Cheers!
@djh_wolf I know…
Ive been thinking about wiring 110v smoke detectors into Konnected. If you have old-fashioned wired smoke detectors, like me, there is a hot (110v constant), neutral, and a signal (Edit: 9v DC when fire is present). This is how all of the detectors beep when one gets fire. One of the detectors was on a wall where the other side was unfinished, so I could attach Edit: 9v fire alarm relay. This would trip a relay, and Konnected would see that as a closed door. This would trigger a fire system where the doors are unlocked and Alexa announces nonstop that there is a fire, as well as sound the sirens.
Also, hubitat is amazing. I am now using hubitat too! It all started with the news of SmartThings stopping groovy. The regular cloud outages and the fact that the security system needed internet made me think of it. $130 dollars was steep, but I was slowly thinking about it. Then, one day, I made a catastrophic error by deleting the virtual switch creator app. Because I did it in the new app, I got no warning that all devices would be deleted. This broke my entire system, and I knew I needed a hub with backup. Now, I have instant, local automations.

Perfect!
I actually have the kidde fireX detectors, which come with a dry contact relay for exactly that! I had them linked into my fibaro, but it’s on my road map for konnected.
Congratulations on the jump, and see you there!
hi lads i have been following your posts with great interest as i am looking to do exactly what you have been discussing. i want to move my existing wired alarm system to an automation system. I have been using smart things to link my home automation such as the lights roboc vac , tv and plugs to alexa. i noticed that you have changed to hubitat. have you used hubitat with your home alarm? if so is there any chance you could tell me how to do so
