I did wonder if that’s what it was for. I have thermostats in all ‘important’ rooms where better control is needed (bedrooms, livingroom and kids playroom) but would like better control in our offices and kitchen etc. Plus as they are considerably cheaper i could swap out the thermostats and sell them on as they are used only as a temperature/humidity sensor any way and never interacted with.
Im not too fussed about the additional devices (temp sensors, humidity sensors etc) , I decided to go with native zigbee devices and use ZHA…
why can’t you ?, the Gen2 supports OpenTherm as well ?

get yourself a OpenTherm Gateway, it has far more control than the wiser could ever give anyway.
here’s a sample of sensors (not all of them).
and a list of Actions:
and an example of how to set Max Central Heating Temperature.

Because it was only supported on Gen 1 with the Multi Kit 1, not the Kit 2 or 3 with stored hot water.

Well I guess I’ll find out when my new gen2 3 Channel HubR arrives.
But the instruction Manual defiantly shows it is supported.
The fact it has the option to switch between OT Modulation and On/Off load compensation might be their way around the problem - OT Modulation supported on Kit 1 and On/Off on Kits 2 and 3?
They supplied the OT module with Kits 2 and 3 on Gen 1 despite the fact the manual states “The communication module will not work on systems with a separate
hot water cylinder (Kits 2 and 3) even if the communication module is
present”, It was “being looked into by the Devs” to get it working with Kits 2 and 3 but never materialised, but with the Gen 2 hub here I can see why they may not have spent too much time on it.
I’d like to be able to use OT modulation, but even if I cant and I can get some of the other OT sensors working either via this integration or with a gateway I’d be happy. I’d be looking for things like flow/return temps, flow speed, exhaust temp, circuit pressure etc. I have an OTGW module I bought a couple of years ago and I tried to get that to sit inbetween the hub and the boiler but I could only ever get the heating or the hot water working correctly, never both.
But saying that, the fact it’s got better wifi capability - the existing hub is the only 802.11g device on my network - and supports the small temperature/humidity modules, if they can be used in place of thermostats is probably enough of a draw for me to upgrade especially with the 40% discount.

I’m not sure I totally understand what you mean. To save the schedules to file:
- Create a
wiserdirectory in yourconfigfolder. - Go to
Developer Tools / Actionsand then select anEntity, plus aFilenameand a folder. - Repeat for each
Entity.
I have multiple schedules for each room, and depending on the time of the year, each one gets assigned to that room, but the action only save the current schedule that is assigned to the room and not all 3 schedules.
Ah, right. I understand what you mean now. In that case, yes, I am fairly sure you will need to activate each one before saving it to file.
It does seem that way. Kind of wish I had thought of this before placing my order for the 2-channel hub. Too late now, as it just arrived an hour ago.
I agree, regarding the bundles. It’s the same price as buying each item individually, so not really a bundle at all. Howewer, at least the 40% discount appears to apply to everything in your basket whether you select a bundle and/or individual items, so there are good savings to be had across the range.
I’m in the exact same situation. Room Thermostats in the most important rooms, but no-one ever uses them and I would largely like to hide them out of sight.
I ordered five headless temperature and humidity sensors (along with the new hub) for all the rooms without a Room Thermostat and may consider replacing some of the existing Room Thermostats with these in the future.
I can see the second hand market being flooded with Room Thermostats in the near future. 
I’m open to anyone who knows better, but there seem to be two problems I see with getting OpenTherm working with Domestic Hot Water(DHW):
- With just OpenTherm control, the DHW water temp is entirely controlled by the Boiler and the tank thermostat is rendered ineffective. More importantly, there is also a safety cutout in my thermostat, set at a fixed higher temp of 80C which I think is required to comply with Building Reg G3, so I think that running DHW solely from OpenTherm may be illegal (and possibly dangerous!).
- When I experimented connecting my Baxi 824 System Boiler to an OpenTherm shield to see what it could tell me, the Boiler no longer responded to the On/Off controls, and had to be switched off at the mains and the OpenTherm connections disconnected before it would revert back to On/Off control.
- You would install a heat probe and uninstall the tank thermostat as it is an on/off control.
- That’s normal, why would you need on/off controls operating at the same time as OT.
OK. So I have an S-Plan system (seperate valves for DHW and CH).
From the programmer, the switched live feed goes to the thermostat on the tank and if the temperature of the stored water is lower than the setpoint on that it closes and sends the switched live on to the DHW valve which opens and in doing so send the calling for heat signal to the boiler.
The bit that then I can’t work out is how the boiler would know what temperate to fire at if it’s expecting a temperature from OT. Either that, or does the controller, knowing that DHW is on and calling, does it send a fixed temperature.
I guess we’ll find out and at £85 I couldn’t not upgrade my controller.
I used my own hard earned cash to buy the 3ch with temp sensors bundle. Can you imagine! Maybe @jamiebennett will find scope in his large corporate budget to send over a test one and each of the new devices so that i can continue to provide excellent promotion and support of their product with this integration??!!

I think you are absolutely spot on!
I’ll start the ball rolling…
I’ll offer £60 for three used displays.
(Please…)
I’ve already made the same demand in France but no response…
I don’t know what system you have, but my system is S-Plan (separate two port valves for each of Heating and DHW circuits) with an unvented DHW cylinder, so great care has to taken to ensure the tank does not become a bomb in the event of failure, and unvented systems therefore require the installer to have an additional G3 qualification in order to legally fit them. I don’t believe a temperature probe is accepted as a suitable protective device as the regs say that, amongst other things, it must be non self-resetting.
This is a schematic of my S-Plan Baxi 824 System Boiler system with unvented DHW tank and an IFOS (In-Flue Outdoor Sensor), ie weather Compensation. The IFOS changes the operation of the boiler front panel control such that instead of choosing a CH Flow Temp, you select a Weather Comp Curve, and the flow temp then depeneds on the outdoor temperature. The higher the outdoor temp, the lower the flow temp. However, if the boiler has a call for DHW from the tank thermostat, the IFOS overrides the selected temp curve and sets the flow temp to maximum (ie 80C). The DHW thermostat then decides the DHW water temp, opening the circuit when the set temp (55C in my case) is reached. There is also a safety (limit) cutout in the thermostat which trips at 80C, and must then be manually reset. The tank thermostat (an ESI ESCTDEB) is (slightly) intelligent and once a week allows the tank temp to rise to above 60C to kill legionella bacteria.
