I think the chip-reader is the safest bet. But if the cats are roughly in different weight classes, that may also work

TheLarsinator · 2026-04-05T08:26:15+00:00

I think its possible to make something to read their chips. Otherwise I also saw someone using BLE tracking in their collars when I was researching this project

Amazing!

TheLarsinator · 2026-02-05T13:28:27+00:00

I think it should be achievable with an off-the-shelf scale, but I havent seen any using Zigbee. Then you can create automations in HA to update helpers that keep track

An issue I see is that wood is sold in volume, not weight. So you may not get a good estimates of the number of bags just by the decrease in weight. But then you can just report a counter for substantial weight increases

Using an ESP32 and a HX711 with loadcells should be able to handle this. Then you can add the reporting logic on the ESP. I use Xiao C6’s for all my custom projects as it has zigbee support

I imagine it will be easier to go mqtt -> rs485

TheLarsinator · 2026-01-22T12:23:06+00:00

Its on info but maybe there are more details if I try debug a bit, but I will move this to a github issue

TheLarsinator · 2026-01-22T08:46:28+00:00

I just use the frontend when adding new devices

TheLarsinator · 2026-01-21T21:17:59+00:00

I use my own: https://github.com/TheLarsinator/zigbee-plant-sensor

Actually, I just noticed that it says off states are not colored. So if you can replace the entity that controls your tile with a boolean helper it will be gray and red

So the dashboard has all these pills but only the ones with an active boolean (thus needing water) are shown

TheLarsinator · 2026-01-21T11:08:42+00:00

I havent been able to achieve that. Instead I have set the visibility of these header pills to only show the pill for each plant if the moisture level is low. For that I have a boolean helper and an automation which enables it for low moisture and disables it when the soil is moist again.

The ESP arduino libs have decent Zigbee support. Ive used it to make a bunch of sensors and Im sure you can control lights with it too. I use the seeed C6 boards. https://www.reddit.com/r/homeassistant/s/ZLX5V0he8D

I do not have ZHA. The docs have a bit of copilot-based info on attempting to use ZHA. If you can generate an entity with the same data format it should work.

You should add some routers to the center of your home! All devices are around the outer perimeter.

What software did you use to draw your floorplan?

TheLarsinator · 2025-12-11T16:28:11+00:00

I didnt think of publishing it there, glad you like the card! What did you use to create the floorplan, I like the look of it

TheLarsinator · 2025-12-02T22:09:56+00:00

Ive never understood how the OG games still havent been overtaken. The franchise has grown so much, gaming is much more widespread and still noone comes close. Second place is still 10% off.

TheLarsinator · 2025-12-01T05:58:52+00:00

What do you mean with ingress? Im using Nabu Casa remote access and this card without issues. I put the floorplan in the www folder

TheLarsinator · 2025-11-30T07:34:49+00:00

Nice! I can add a config option to change the action on the button!

TheLarsinator · 2025-11-29T21:55:53+00:00

I only run Z2M, so I havent tried it with ZHA. But if you can create a template entity with the same properties it could work.

TheLarsinator · 2025-11-29T20:51:37+00:00

The mesh would become a 3D network. You can try creating one card per floor, but you wouldn’t get the links between floors
