  • I’ve got a decent number of local manual controls, but not all of them. For example, some of my wall switches operate the relay because they are just turning on and off the power. Others I have disabled the relay on because the lights themselves are WW/CW tuneable and HA controls the colour during the day.

    I’m wondering about having another look at zigbee groups and commands for the simpler automations in the house. I avoided these because they aren’t really visible to HA and I didn’t like having two automation ‘languages’ at the same time.

    Overall, how long do you think you could cope without your HA platform before it becomes an issue?


  • I was thinking about matter yesterday, I like the idea of being able to have multiple controllers. My house is half wifi devices and half zigbee. I’d been favouring zigbee recently because I don’t want to swamp my network with device packets, but maybe that needs a rethink. At the very least my wifi devices all have esp home configs that could be configured to fall back to defaults.




  • I totally understand mission critical motivations, but I reached a different conclusion from you. I’ve been HA’ing for a long time and everything dies eventually.

    Do you have a backup HA green in the cupboard? my wife would murder me if I couldn’t get the house back in 24 hours. I want to use hardware that you can buy literally anywhere so I don’t need to keep a backup.

    I’m not there yet, but I havve moved to running HA on a proxmox server and have used my HA backup to recover from a software failure. I’m now thinking about what the same would look like for a hardware failure, either the mini pc or the zigbee dongle.


  • I like this, but I don’t like that rooms are cold unless I hang out in them. I live in an old stone house and I’d rather have a room schedule than a room presence sensor.

    I’ve done something similar. I use the excellent scheduler from Niels Faber. I have room radiator TRVs. I have a helper entity that counts the number of radiators that have an open valve, and an automation that triggers when this changes to/from zero. This automation adjusts the central nest thermostat, converting it to more or less a posh switch.

    My radiator valves use Better Thermostat and external temperature sensors, and the whole thing keeps my house warm in every room. I need to write a GH blog post about it, but happy to answer questions/share bits of config








  • I don’t know how tech savvy you are, but I’m assuming since your on lemmy it’s pretty good :)

    The way we’ve solved this sort of problem in the office is by using the LLM’s JSON response, and a prompt that essentially keeps a set of JSON objects alongside the actual chat response.

    In the DND example, this would be a set character sheets that get returned every response but only changed when the narrative changes them. More expensive, and needing a larger context window, but reasonably effective.
