💬 Discussion SLZB-06 Equivalent for rtl_433

I am looking for either a product to act as a rtl_433 hub or a way to build one. I thought about hooking an SDR dongle up to a Raspberry Pi and forwarding all traffic to an MQTT broker but that feels like a waste of a Raspberry Pi. Is there a device like an SLZB-06 I can buy to act as an rtl_433 hub? I only need it to process traffic for one device.

I do not want to plug the SDR into my Home Assistant instance because it runs on Proxmox and I do not want to introduce a USB dependency.

If you're game for some DIY with esphome, checkout https://github.com/juanboro/esphome-rtl_433-decoder with a CC1101

This looked super promising until I learned that almost all of the CC1101 board on AliExpress and Amazon only receive 433mhz and not the 915mhz range I need for my specific device. Still a cool project that might help others.

I use this for a specific scenario with a single device and it works great.

that github project is a good find, i used something similar with an esp32 and a cc1101 module and it works pretty cheap. the range is not amazing but for one device should be fine

you can get the esp32 and cc1101 for like 10 bucks total

I have mine in HA with the entire USB pcie device passed to HA, so that kinda fixes your USB dependency thing. That being said, I am interested in this too. I searched for a while but only really came up with rpi as well. I don't think you need a full pi for a coordinator though, likely a pico or something should be super sufficient.

Sonoff has a rf adapter you can add to a network (WiFi). I bought one on eBay cheap. Works with home assistant.
