I’m moving into a new house in a couple of months, and the house comes equipped with a DALI lighting system from Helvar called Digidim. If I remember correctly, it comes with at least two (or even three?) Digidim 910 routers to be able to support all light sources + a couple of PIRs. The routers will be connected to a local network switch that allows you to communicate with them over the local network.
I’d like to integrate this system in Home Assistant, i.e. read states (which lights are on?), listen to updates (light was dimmed), and send commands (turn off light). My challenge? I don’t have access to the system / the house yet, and there seems to very few folks here running DALI systems together with HA so there’s not much I can read up on in advance…
I did however find a brief mention of support for DALI gateways while scanning the KNX light integration in HA. Is anyone using that? I assume I’d need multiple KNX-DALI gateways since each gateway only supports 64 DALI devices… which seems like a bit of a hassle, but might be worth it if it “just works”.
In a better/perfect world, I could see my Helvar system communicating with HA over e.g. MQTT. This seems to be possible by purchasing a couple of DALI-MQTT gateways, but again - it feels a bit sad that I’d need extra equipment for that.
I also found @dgomes DALI <-> MQTT bridge, but again: that seems to require an additional USB device hooked up to the DALI bus. The bridge itself uses python-dali internally, which might be my last resort here.
Again: I do have the DALI routers from Helvar connected to the local network, so I assume (which I maybe shouldn’t, given that I can’t find any information on Helvar’s homepage) that I could communicate with the DALI lights/PIRs over TCP/IP… somehow
At this point I’m somewhat confused, and would be eternally grateful for advice from folks who’s been up for similar tasks - please hit me with your best tips and tricks!
