I’ve made good progress figuring out the APIs and connection settings for the Signum, and I can now trigger actions through the APIs (still in the early stages, but it seems to be working). However, I’m noticing a significant delay – sometimes up to 30 seconds – when controlling blinds or lights, which isn’t ideal.
I’m moving to my own Home Assistant server, as the Signum seems underpowered for my automation needs and struggles with performance.
Has anyone else tackled this issue or found a way to reduce the response delay?
First off… I have to confess that I don’t use HomeAssistant. No doubt someone who does (there are plenty on the forum) will be along here shortly. But I am a software developer, and I am curious about what might be going on.
30 seconds certainly seems a very long time.
I note that Signum is a Raspberry Pi-3 Compute Module (CM3) internally.
HomeAssistant web site says, “neither the Raspberry Pi 3 Model A nor Model B have enough RAM to be stable”.
If this is causing the CM3 to page memory (to SD card… not great) in order to run then that will slow HA hugely and will eventually wear out the SD card (as SD cards wear they become slower and eventually fail altogether).
You should be able to run everything you need, and more, on a Pi4 or Pi5 with more memory. What particular features of the Signum do you need?
I use the Odroid C4 devices, we’ve sold hundreds of them to run openHAB etc
Recently I tried installing HomeAssistant from the software menu.
It takes its sweet time to fully deploy, but so far… It’s running very well.
Best week… I’ll be leaving one on site for a BBC show… With a local chap being left to manage it for the end user… I’m not allowed to give any more details
