Drayton Wiser Home Assistant Integration

Frazzyfin · April 14, 2022, 12:53pm

When a room is being boosted and I then manually change the setpoint, I would have expected the entity to cancel the boost and go into the manual override state. As it stands it shows that it’s boosting but the heating isn’t on (because I lowered the setpoint), which doesn’t make much sense. Is this a bug?

@Frazzyfin This is currently how the Wiser App works. Whether it makes sense or not is probably different for different people. Please raise an issue on our github page and we will ask the community to up vote it if it is a change that they want to see. Thx

With the release of HA 2022.4 came a new feature - Trigger Variables. For any of you who are using the recipe for managing temps with external sensors, this has allowed a significant simplification of that automation. In fact, I have also split it into 2 automations to make it much simpler to manage/configure. Recipe is currently in dev branch on our github but here it is below.

Welcome any feedback.

# Using External Temp Sensor to Manage Room Temp Accuracy V2

The basic premise of this automation is to monitor a series of external temperature sensors and boost wiser room heating to reach the correct temperature as set by the schedule, which is one of the failings of having the temp sensor in the iTRV as it is too close to the heat source to be truly accurate for a whole room and often shuts the heating off before the room is at the correct temp.

On updates from the external temp sensor, it will compare this to the scheduled temp of the Wiser climate device (aka room).  If the room is not already heating or boosted, it will boost the room by 1.5x (adjustable) the difference.  I have found this to give pretty good results but this may need tweaking for your own home.

It will also look if the current room temp is within 0.5C (adjustable) of the scheduled temp and cancel any boost if it is.

## There are 3 requirements for this automation to work:

1) You need at least version 3.0.20 of the Wiser integration for HA.  It uses the 'current scheduled temp' attribute that was new in this version.
2) You need at least v2022.4 of Home Assistant for the trigger variable functionality
3) That your temperature sensors are setup in HA Areas with the Wiser Climate device you wish to control in the same area.

## Changes in V2

### 1) Splitting Into 2 Automations
I originally tried to write this as a single automation (which worked fine) however I think it added quite a bit of overhead to HA as I could only trigger it on all state changes.  It was also very difficult to debug as each state change for any device triggered it and therefore traces contained triggers not for what I was interested in debugging.  As such, it is now split into 2 main parts.  
  - Part 1 (Fire Event When Room Monitoring Temp Sensors Change Reading) is the automation to monitor for temperature changes in the devices I am interested in and fire a customer event when a temperature change is registered.
  - Part 2 (Manage Wiser Heating From Ext Temp Sensor) is the automation, triggered by this custom event to find the Wiser Climate device in the same room as the temp sensor and boost/cancel boost where necessary.  It also logs key informaiton in the logbook so you can see when it has activated, what the schedule temp/sensor temp was, how much it boosted by etc and also when it cancelled a boost.

Looking for some feedback on a possible new feature for this integration. It would use the fantastic zigbee2mqtt-networkmap card by azuwiz to display how all your devices are connected in the zigbee network. Should we do this? Would it be useful? Image below of how it would look.

tombadog · April 29, 2022, 10:25am

Yes, this would be great and very useful!

Does anyone have experience configuring the Eurpoean Wiser hub from Schneider? I have installed Drayton Wiser Integration for Home Assistant through HACS and I’m all good to go . I also followed the instructions on how to obtain the api secret however that’s not possible. In AP mode I have checked the IP address but in my case http://192.168.220.1/secret does not provide a response. Any suggestions?

Angelo_Santagata · May 3, 2022, 10:45am

I dont… , is it a later firmware?

tma · May 3, 2022, 10:47am

The firmware version is 1.62.4

msp1974 · May 3, 2022, 12:08pm

That’s not the IP address. Following the instructions and connecting to the hub AP directly creates a different network using the hub AP address range. You need to use the IP as per the instructions.

tma · May 4, 2022, 6:57am

The network when accessing the hub in AP mode is 192.168.220.0/24. The phone gets the address 192.168.220.10. Following the instructions and going to “http://192.168.8.1/secret 1” does not work. I have tried connecting using the IP 192.168.220.1 instead but that doesn’t work either. Any suggestions?

msp1974 · May 4, 2022, 10:06am

@LGO44 are you able to help here as you have the EU hub?

Angelo_Santagata · May 4, 2022, 11:17am

its been ages since I put the hub in AP mode. Not at home now but if your network is 192.168.220.0/24 then try http://192.168.220.1/secret (without the 1, its a typo in the docs)

I’ll check it later tonight when Im back

tma · May 4, 2022, 11:51am

Thank you! Just for the record I did try http://192.168.220.1/secret (without the 1) also without any luck.

I use Fing on my phone when I have to deal with unknown networks.

It helps me to find any other devices on it. It has a feature also to do a port scan on a device to know what is open.

Angelo_Santagata · May 4, 2022, 1:50pm

Fing could help actually… We need to find the ip address of the wiser hub and then (assuming the EU version is the same as the UK) /secret to get the secret out of the hub…

GSzabados · May 4, 2022, 2:28pm

Can you tell us which model of the Hub you have actually?

There are actually a few of them.

tma · May 4, 2022, 2:56pm

It’s the Wiser Gateway (550B1001). https://www.lk.dk/produkter/?iid=550B1001
Firmware version is 1.62.4

Angelo_Santagata · May 4, 2022, 3:09pm

Right, here is the issue, this integration was primarily written to support the UK Drayton Wiser solution for heating (see here https://wiser.draytoncontrols.co.uk/how-set), not this gateway… I know Mark @msp1974 has been working with @LGO44 on getting some EU hub features working but given we dont have the hubs its been difficult to get working…And after doing some googling I think there are quite a few different wiser hubs/gateways,…

GSzabados · May 4, 2022, 4:06pm

And some works together with the Heat Hub and standalone as well, which is the most confusing… (Wiser Home Touch).

GSzabados · May 4, 2022, 4:13pm

As @Angelo_Santagata said, this is not the Hub which for the integration has been built,

BUT

Assuming that the Hub operates the same way as the Heat Hub, you can help to reverse engineer it.

For finding the secret, you would need a computer running WireShark connected to the Hub’s AP and do a commissioning of the Hub. When the Hub commissioned the mobile app, in theory, should acquire the secret, and set the Wifi settings. What could be captured by WireShark when happening.

On the other side, there is a way to connect that Hub by Ethernet to your network, so must be another way to acquire the secret, not just through the AP mode. Which suggests that the secret might be available when the Hub is in a factory reset state, before commissioning.
