Mill heaters won't connect to WiFi

ampennick — Fri, 15 Apr 2022 12:16:02 GMT

Had two Mill wifi heaters (AV1200W) for 3 years. One died so bought a replacement. Couldn't get it to connect to EE router (changed settings according to their website and still nothing). Reset router settings as it killed my Google Home connection and now I can't get the old heater to connect either.

Both connect to a mobile hotspot so it's definitely something on the router side but EE have advised that they can't support as the router connects to other devices (so it's not "faulty").

Anyone else have experience with similar and know what I'm missing? Tried disabling 5GHz, disabling firewall, selecting channel 1, tried all 3 WiFi modes, DHCP and WPA2 are enabled. I'm out of ideas!

For an EE Smart Hub, but not an EE Smart Router, try separating the wireless bands/SSIDs. On the Advanced > Wireless Settings page of the SH there is a button near the top to Separate the Bands. Turn it ON. Then the 5GHz SSID will appear starting with "5GHz-" & the 2.4 GHz SSID not starting with "5GHz-". Then connect your devices to the 2.4 GHz SSID if they can't do 5GHz. The Smart Router doesn't allow this.

Did you ever get yours working? I've just bought a new Mill Wifi heater and I cannot get it to connect at all

@damianwebber have you tried the suggestions above?

Nope, never managed it. Ended up returning the new heater and will be binning my old one too next month.

Thanks EE!

TBF the Trustpilot page for the Mill heaters is riddled with poor reviews. Bad app, poor connectivity, only work with older routers etc. So no, it isn't just EE. Not sure I would have much confidence in a heating system that's tied to your router anyway.

My existing radiator was fine. In fact, it's a great piece of kit. But get this. Since I tried connecting the new radiator, my existing radiator isn't connecting. My radiators actually use a Archer C50 router configured as an access point but my main router is EE (hence coming here - I thought it might be firewall config or something).

Mill have tried suggesting a few things but no luck - i expect their engineering dept is pretty small

I had a look at my access point and EE router. I can see the MAC address of the heater registered on both network devices.

in fact, the heater’s Wi-Fi light is lit green so seems connected. Then checking the room’s statistics I can see that energy use is being collected.

the only (major) fault is that I cannot see the actual heater in the app. What’s that all about? It must be some sort of firewall or NAT issue.

any ideas?

Did you ever fix this problem? I'm having exactly the same problem with a Gen 2 convector heater.

Thanks.
