I’ve just updated and mine is the same, although I have Gas Boiler set instead of Oil Boiler. It’s also missing the Control Type option that was present in the previous version. Looks like a bug to me.
Thanks for the feedback. Strange this one, I’ll pass it on to the team to fix.
Wiser works with heat pumps and it is an option as the source type. Wire up the ‘external controls’ input of the heat pump to Wiser.
So it is!! Ive never looked at that part of the app for… sooo long
Hello, Thank you a lot for this integration. I was messing with Schneider apps and this brings me all I need (and more) inside home assistant
Defining schedule is so easy compare to what it is possible in the app.
Is it possible to user Wiser devices without connecting the hub to the internet? As I see I’ve everything maybe except the device association?
I would like to remove internet access because I discovered recently the hub consumes my bandwidth ( > 20Mb/s) and I really don’t know why?
Does the integration communicate only with the hub or it needs a connection to the Wiser cloud?
Thank you a lot for all the work
There seems something very wrong there. My Wiser Hub has transferred approx 100MB of data in total over the past 5 days since the router last restarted. Are you sure the 20Mbits per second is correct that that equates to approx 9GB per hour.
Almost all of the Wiser Hub traffic should be local to your network and not touch the wider internet
my wiser hub is connected to the wiser cloud so it communicates. i have to isolate the wifi in order to have better information.
the only information i have is from my ISP box which something like this:
in green is what the hub is sending which is near 20Mb/s all the time
Does it matter which kit i should order if im using heatpump? They have configurator on their site which asks me to choose between combined/conventional boiler.
As the wiser system is smart, and learns how zones respond to heat over time, shouldn’t all of the lock shield valves be fully open & let the wiser system balance the system instead ?
It’s probably best you raise a question with Schneider to identify why you are seeing this volume of data traffic.
The combined v conventional will be whether you need a 1 or 2 channel controller. Ie a 2nd channel for hot water. If your heat pump has different controls for heating and heating the water you will need the 2 (conventional). If not, just the 1 (combination).
AIUI ‘works locally’ means this HA integration communicates directly with the hub and not with the wiser cloud.
However I’m not sure to what extent the hub functions when deprived of WAN connectivity.
No WAN access certainly means no firmware updates. Also, probably, no working eco/comfort mode or insights.
Whilst here, the bandwidth it consumes doesn’t seem to be 20Mb/s, it certainly seems to send a fair volume of data. I confess to being uneasy about this and keep meaning to try it out firewalled off like the other IoT devices I own.
Thank you very much. Yes the pump has controls for DHW separately (which right now i doesnt use). It commands a 3-Way valve to heat the boiler. So i have to order the conventional kit?
I would. You can also choose not to use HW output until you’re ready but will save you regretting it later down line.
Should say there is also a 3 channel hub for 2 x heating zones and 1 x hw.
Great, i bought the Multizone Kit 2, 2 channels for conventional boiler. There is Black Friday btw where the kit in bundle is 100 pounds discount.
I think the main issues you will have by “stopping internet access” is
- Unable to control it via the App when away from the local network , obviously you can use HA
- Firmware upgrades (you mentioned this)
- Finally, I think I read somewhere that the initial setup requires the cloud…
thats all I can think of.
Be interesting to see what data is being sent out, are you able to wireshark it?
Just because you are seeing 20 Mbps bandwidth use by the Wiser Hub reported somewhere doesn’t mean it is consuming 20 Mbps of your bandwidth all the time. It means that it has peaked at 20 Mbps at some point, which could be very short.
For example if it transferred 20 kilobytes in 1 microsecond this would equate to roughly 20 Mbps. (21 * 1000 = 21000 kilobytes per second = 20.5 Mbps).
Even if it does that frequently (every minute even), it may still not have a noticeable impact on the experience of using your internet connection.
If it keeps this up solidly for consecutive minutes or hours then you have a problem, but if it just does short bursts, you aren’t likely to notice it.
If it did seem an issue you could use QoS or bandwidth limiting of your Wiser Hub on your router or access points, without cutting it off altogether.
If your primary concern is privacy, then it is a different matter and cutting it off from the internet makes more sense, IMHO.
@dunxd @Angelo_Santagata I agree!
@valvin was concerned about the bandwidth utilised by the hub. I did not measure that, but I noted the connection endpoints and volume of data sent over time. Other than DNS, all traffic between hub and WAN is encrypted, as you’d expect these days. Encryption is a double edged sword!
I connect to the hub & HA via VPN. So do not require the cloud in order to reach the hub. But I have a feeling the hub may not function as expected with out WAN access. Even if one forgoes eco/comfort modes and insights, the hub doesn’t seem to like being disconnected from mother ship for too long
EDIT: Re connectivity needs, I am guessing the hub requires cloud services for telemetry, eco, comfort and insights. So, I wonder if ‘normal’ heating control (on/off & TRV demand) occurs entirely locally.
In general, if you have concerns regarding privacy with these IoT devices that require cloud connection to function correctly, isolate them onto their own VLAN that denies all access to all networks except its own subnet and the internet.
That way, who cares if it phones home or whatever. It can’t collect any sensitive data, only status/activity of itself, the WiFi AP and other IoT devices on the VLAN.
If you think about it, the hub is designed to and will function fine without WAN (Cloud) access and it does, as I can attest to after having an Internet outage for nearly a week (thanks to Virgin being so unreliable in my area currently). However, you will lose functionality like ‘weather compensation’, as it clearly needs WAN access to retrieve temperature and weather information, also firmware updates etc. For regular users that aren’t integrating with Home Assistant, they will obviously lose remote access and for us, we lose the ability to use the app when not at home (alongside the Home Assistant integration, which for some is important, as it allows non-techie family to just use the app).
AFAIK Wiser is the most unreliant on the cloud of all the smart thermostat systems and we should be grateful for the fact it was designed to work without a WAN connection, even if it is with reduced functionality.
If I had gone the other route and chosen Tado, I would have been in a far worse situation with the Internet outage, with barely any control or functionality. As far as I understand it Tado has all it’s schedules stored in their cloud, rather than locally, so the system would probably have pretty much stopped functioning.
That was one of the deciding factors (this Home Assistant integration being the other and main one actually) that I chose Wiser over the other options.
