Drayton Wiser Home Assistant Integration

Hi @xjackh ,

Unfortunately, this is not how the hub works. The channel on/off is driven by the assigned trvs, roomstats etc demaning heat and are not controlled directly. You can set the temp of devices to drive the channel on though.

Opentherm also only works on channel 1 afaik.

Hi @msp1974,

Can you think of any way of getting around this with the integration in its current state?
My current theory is to get some Shelly/Other smart relays and activate them based on HA automations from this integration. Eg, Room X requesting heat, fire shelly relay for X heating loop. Room y, Shelly Y for Y heating loop.

Struggling a little with what you’re trying to do as your description seems simple. So, when you say room X turns on, what do you mean by ‘turns on’?

Normally for a 2 zone heating setup, you assign different rooms to the relevant zone (needs to be done in app). Then when the room calls for heat (hub algorithm and cycles times permitting), the hub activates that zone relay (turning on boiler and valves as setup).

What am i missing about what you are trying to do?

See the above diagram as I’m bad at explaining. I do not have smart TRVs.
When room thermostat X hits the desired temperature the boiler turns on and delivers heat. Zone X valve opens and heating zone X gets heat to the radiators.
When room thermostat Y hits the desired temperature the boiler doesn’t turn on but Zone Y valve successfully opens.
The hub communicates with the boiler using Opentherm only via channel 1. Channel 3 doesn’t tell the boiler to do anything as Opentherm is only channel 1.

Is there a way I can get both zone valves to open with both room zones communicating over Opentherm? The only way I can think of with limited knowledge of the integration is to do automations with smart relays whilst having all of my rooms on Channel 1 on the app.

Ah,ok. Understand now. Im not sure i have a better option than you describe. I dont have OT but i know many on here have. Anyone have any thoughts to help Jack?

Has anyone with a 2nd gen hubr had any issue with WiFi? I have had another instance where the setup light on the hubr is flashing red, HA integration says the “HeatHub Signal” is invalid but I can access the hubr via HA and the Wiser app.

I have discovered that this issue happens when WiFi goes off and is restored, the hubr reconnects to WiFi and picks up its ip address and continues to work ok but the setup light flashes red until I power the hubr off and on.

Mine always shows this with HubR gen2, no idea why

I’ve had a couple power cuts over the past few weeks and I’ve had to reboot the hub at the mains to get it to reconnect to WiFi.
