Need a RUBBISH network switch...!

katie279 · 9 May 2024 at 07:14

Hey all,

Got a strange one - my tado thermostat has started playing up randomly and looking online there's lots of posts (including tado themselves) who say that because they use an aging half duplex network style, it can cause issues with newer switches who are discontinuing this.

Their suggestion is to get a cheap 100mbps half duplex switch, connect the tado bridge to this and it'll resolve.

This sounds bonkers, but can anyone tell me how I can get one or check my existing ones?? I've got various old switches, but pretty sure I'd have gone with gig speeds even 10 years ago?!

I've tried looking online, but almost everything seems to be 1000mbps (no surprise!)

Any help appreciated!

If you have a managed switch you should be able to set that manually on the port. UniFi allows it as an example.

Ah good shout - yes, have a UDM Pro, so should allow.

Because it's super difficult to type "10/100 switch" into either Overclockers or the main online shopping site?

My basket at OcUK:

1 x TP-Link LS1005 - 5 Port 10/100Mbps Desktop Network Switch (SKU: NW-21W-TP) = £7.49
1 x TP-Link LS1008 - 8 Port 10/100Mbps Desktop Switch (SKU: NW-21X-TP) = £8.99

Total: £20.47 (includes delivery: £3.99)

Well I didn't realise that such slow switches were still available - I googled briefly, but everything was gigabit.

Anyway, Chris' advice has saved me £20, so I'm glad I asked, we learn more by asking, not by preaching after all....

Thanks Chris - super helpful. They actually recommend a 10mbps hdx which is bonkers to me, but it's great that the UDM has this - and your screenie has helped save me hunting!!

Most unmanaged switches would negotiate down so there might not be a requirement to set it manually. Either my Hive or Hue runs at 10 Mbps as an example on my USW Pro 24.

Yes, it's most peculiar, it's been running pretty much fine for 5+ years, so I'm clutching at straws a bit to work out what's happened - but thought I'd try!

FWIW, my Tado Bridge is connected directly to my UDM Pro, and the port is set to 'Automatically Negotiate'. So it's perhaps something specific to your bridge/setup which is the issue?

Yes, it ended up being the UDM/U6 Pros. The tado is notoriously poorly coded, so it doesn't handle odd conditions well at all (or degrade gracefully) but this was a very weird issue on the UDM side.

Raised with support and they shared a pre release firmware fix that resolved immediately....

Glad it's sorted!

Did that also fix your wifi issues?

Yep, all disappeared instantly!
