Digital Inputs add more

[Chris Pitman]

Was looking to swap to white wing dimmers to add more channels, currently have a couple loxone 4 Ch Dimmers and using some of the digital inputs on one unit, what options are there to add more digital inputs to loxone if I remove the dimmers to free space, I see loxone DI extension but quite expensive any other options?

I'm happy to go off-piste with outputs like dimming and relays (used DMX, KNX and modbus RTU all with good results) but for inputs I quickly settled on always using the Loxone DI extension. 

Yes it's relatively expensive  - but not absurdly so in the grand scheme, and it's compact, robust and easy to setup and low latency.  I've looked at modbus input modules but the latency is unacceptable for most user-driven interactions because it has to poll the inputs.  Using something like this you could cook up a custom RhPi to TCP/UDP protocol rather than use RTU, but that is really obscure and not much cost saving once you factor in the RhPi itself.

If you only need a couple inputs then https://shop.loxone.com/enuk/nano-di-tree.html may be more economic.

But also, why not just keep the Loxone dimmer(s) along side ? They have much higher power rating so maybe useful for some circuits.

you could use a Shelly i4 (either in 240v or 24v version - i know its wifi but they are cheap and reliable (assuming your wifi is ok)

I've just replaced a couple of Shelly relays I was using (in plugs) with a Loxone Air module.  It will depend on the use case but I was finding the response time was really variable.  using it for a light, sometimes the light would come on immediately the command was sent. Other times it would take some seconds - long enough that I'd think the button press hadn't been registered so I'd press it again.  

It's not an issue for all use cases (I have one on my printer and the wake up time is long enough any delay is immaterial) but no good for lighting.

Thanks for the reply's looks like most stable solution is either DI or keep a dimmer as said (cabinet getting quite full tho)

There's a reasonable market for used mains dimmer extensions so if you sold both you should easily cover the cost of a DI extension.
