An update on WiFi issues. Unfortunately we thought we had a fix but it failed over the weekend on a trialists hub. We continue to investigate, thanks for being patient with us.

They often get stuck too over years of use. I had to replace two of mine recently because of exactly this and I suspect another is playing up (not opening fully). The valves are many years old though.
Ok so progress on the Yorkshire project. Having fixed some of my heating system issues identified by my data, I have seen a pretty significant reduction in gas use. I would say that without the great data available from the Wiser system, I would never have identified these issues as we never run around the house checking each room on a 10 min basis! 
Anyway, below is my gas usage graph for the past few days. Can you see when I fixed the issues? Still have the office issue to fix fully as it seems I have a balancing issue. This is by far the furthest radiator from the boiler and it does not get very hot like the others - however it is the newest in the house!
Couple of other things to note.
-
I did set my office to heat with the rest of the house from 7:30am instead of its previous 9am to see if combining would save any energy (as is the big question on this chat). I can say, it may have actually cost more. This could be to do with the issues I have with this radiator but my (not so overly scientific) analysis would confirm that heating individual rooms as and when needed rather than trying to overly combine makes the most sense.
-
If I keep the same level of gas reduction up this equates to about Ā£60 pm saving. Not bad for a little maintenance effort!
-
Iām now also tracking outside temp in my graphana graphs to see how rooms demand/loose heat more as the weather gets colder. The outside temp has been pretty consistent for the past days so the savings showing are real and not a cause of temp fluctuation.

One thing that has changed significantly (in the SE at any rate) since 11/11/22 is the relative humidity. Itās been up at 100% much of the time. Iām not sure what if any impact that has. It makes things feel colder when thermometers say otherwise.
So true
Oh news, after so long at not having experienced the āredā light disconnect issue I faced my first one yesterday 
It sorted it self out by itself after about 20minsā¦ I only noticed because I wanted to manually boost the living room from HA>
I have experienced this past week several 2 hour disconnects (solid red only), all of which recovered and all of which occurred shortly after midnight. Then, one flashing red event which did not recover where I resorted to toggling the hub setup mode. I had had a very good run prior to this 
I wonder if high relative humidity affects wifi?
@Angelo_Santagata Welcome to the club! Very late to join the party!
@darcey - humidity may affect wifi signal (so many things can - even walking passed it!) but I donāt think this is the issue with the hub drop offs. Or more precisely why the hub does not reconnect quickly to a wifi loss. See my ( 3 hubs now ) below. The first is my actual hub with all the devices connected. The āSpareā is my dev hub and the āTrialā is a Jamieās team hub running different firmware trying to get to the bottom of the issue. They are all sat on the same mesh node within 1 meter of each other. Quite different behaviour!
The tank meter is my ācontrolā device - an ESP32 device about 5m away from the same node in the garden.
Maybe Iām not interpretting your chart right, but live and spare unit look quite similar. My hub was running great, until last week when I experienced a series of drops of similar duration and similar time of day. Looking at the hub wifi strength, thereās no indication of deteriorating wifi signal.
I have a SMETSv1 meter (EDMI British Gas) which octopus dont support and finally when I called the this week they said they can now upgrade this to a SMETSv2 meter! hurrah! It was delayed because i have three phase at my house (very weird and awesome at the same time). Im on octopus btw

I have spoken to at least a dozen different people on whatsapp, live chat and telephone at EDF since April this year, each one gives a different answer and seems to have no knowledge of any previous conversations, or supposed actions that were taken by previous agents.
I understand that the upgrade from SMETS1 to SMETS2 is an OTA upgrade, can be done remotely and takes very little time.
So I was told during one session with them, that the OTA had already been done, my meter had been upgraded, and all that required was for them to be commissioned which would take a bout 48 hours - great !
so about 3 days later I checked the web portal, and it showed no data, so I contacted them again, and was told by the agent at that time, that my meters had not been upgraded and that they were working on it, and basically they could not tell me whether it would take a week, a month or a year to fix them.
there were several chats / calls thereafter, and my conclusion of each one was that there was no priority whatsoever, and no incentive for them to do it.
On 26th October I spoke to them again and was told āThe meter in your property is not a generation 2 smart meter it is a generation 1 smart meter. I have already escalated the eleigibility request to our smart team to make your property smart meter 2nd generation eligibleā - great !
So I called again yesterday, and after waiting an hour to be connected, was told that thereās no record of any eligibility request being made, and that they would fill in the form now, please wait while I put you on hold, and that was for 20 minutes, took them 20 minutes to submit the request for upgrade.
I dont know whats happening with support / customer service these days, ever since Covid which appeared to be an excuse for everything, it has continued on.
I have no confidence that my meters will be fixed this year, and probably not next year either.
Just been looking at some of the history graphs for scheduled heating and observed that the heating is often boosted an hour or so before the scheduled on-time.
This boosting appears to roughly correspond to āsunsetā time, and wondered if it would be logical for an automation event to advance the schedule at sunset, particularly in the living areas of the house ?
Thatās quite a nice idea to get around the fact that you cannot have dynamic schedules on Wiser heating. For note, dynamic schedules of sunrise/sunset are available for lights and blinds in the EU.
If you set your on time to be after latest sunset and then have an automation to advance schedule at sunset, hey presto, dynamic heating schedule.

They are quite similar but if I show a wider time range, the live unit has many more drops than the spare. Only difference is that live has devices linked to it but both on same firmware, both poll to HA at same rate and they are physically sat on top of each other.

I think this is probably a question for @jamiebennett, but if anyone else knows the answer to this, please jump in. I wasnāt able to determine this from the Wiser website.
Can a single channel hub be used for hot water in the situation where someone already has a smart thermostat (Netatmo in this case) for their heating and a separate ādumbā timer for the hot water and they donāt want the expense of replacing the existing smart thermostat and TRVs? Or would the two channel hub be needed and just leave the heating channel unconnected? I know someone in this situation and said I would try and find out.
Also, can the hub be purchased without the Room Thermostat, as this would not be needed in this situation, regardless of whether the one or two channel hub is needed.
Ha ācustomer serviceā ā¦ sounds familiar - my DNO is SSEN and Supplier is Octopus - I am having the supply moved by SSEN from inside to outside and they told me Octopus have to move the meter. Octopus say they canāt as by law they are not allowed to move from one wall to another, and it has to be done by the DNO. SSEN say they are not allowed to touch the meter as itās not their equipment and they are not licensed to do so.
On the other hand, if SSEN move the supply, therefore disconnecting me, by law, Octopus have to reconnect me - so I said they can fight it out when they all arrive.
Utter madness!

Short answer - YES, but it depends how dump timer is controlling hot water. As far as Iām aware conventional boilers are either sending heat to hot water tank or sending heat to radiators, it canāt do both at the same time. Wiser hub is just a relay at the end of the day (unless OpenTherm is used) , so if dump timer only opens or closes single circuit, you can use Wiser hub as smart relay. On that note I would just buy any HA compatible relay as itās much cheaper.
Thanks. Itās not actually to be connected to Home Assistant in this case, as itās not for me. I am thinking that the 1 channel hub will be looking for a thermostat to control the relay, rather than acting as a simple on/off relay in the Wiser app, as the HW channel does on the 2 channel hub, if that makes sense?
Single channel is for heat only Iām afraid (combi boiler). As for kits without a thermostat, unfortunately not but there are some cracking deals out there this week including a kit 2 with thermostat for just over Ā£100. If you are into energy monitoring too, Iāve seen the Wiser plug (which has energy monitoring and acts as a ZigBee repeater as well as on/off control of course) for around Ā£25.

You can buy Tuya compatible wifi relay like this https://www.amazon.co.uk/Breaker-XUELILI-Controlled-Compatible-Support/dp/B09NYBKX6 and use Tuya app to create schedule, wifi obvioiusly required, but no need for HA. If you want to go Wiser way, buying just hub for conventional boiler would work as well (you would just use hot water controls and ignore heating side on both app and relay) - again all dependant on how hot water controls are implemented.
As Iāve mentioned, Iām using conventional boiler hub on combi boiler (moving soon to house with conventional boiler) and just ignoring hot water controls.
