Honestly, L1T NEEDS to make IoT the way it should be.

Allegedly “Thread” is supposed to do this. But it’s been delayed another year. It’ll be a consortium of standards for *secure* interop. I suspect it’ll be much more complicated than MQTT and Pub/Sub which is a bummer, but at the same time it’s probably needed. Fingers crossed it’s not a disaster. I think it’s been delayed another year again though you can pull up the current state

using it with tasmota for around 2 years and a great benefit is that most sensors are much cheaper than the fancy protocol ones. the range depends mostly on the sensors and thats the only negative thing i can see

A standard RfxCom USB transceiver works out of the box for all 433MHz devices. Using it for years with several home automation systems. It never failed me in all those years. Yes, it's a bit more expensive than a Sonoff, but it's just plug and play.

raspberry pi with dvb-t antenna (via usb) and rtl433 does a lot with 433Mhz. besides other things, get the temp/humidity date from my TFA Sensors and my Pool Temperature Sensore :-D

I have been using this for a few years now (home assistant) with PIR sensors and touch remotes and switch remotes, but have recently migrated to esphome and the difference is amazing, I found with tasmota some sensors gave 2 codes so didn't work 100% of the time. The challenge with esphome was soldering that damned wire on to the chip. I have over 30 entities linked to it 👌👌

Another option (at least in Europe, no idea if it is sold in US) is the rfxcom USB transceivers for 433 mhz. I have a first gen 433trx hooked up to a raspberry pi. Still going strong after ~8 years. No limit on the number of devices it talks to, unlike the device covered in this video. Not quite as advanced as a software defined radio, but it can do some raw packet sending and receiving if I remember correctly. It integrates nicely with domoticz (which is what I run), though these days home assistant seems more popular, and according to a quick search it should work with that too.

Did this a few months ago but switched to a cheap usb SDR with RTL_433 since it couldn't decode my lacrosse temp sensors or work with my wireless food thermometer. Have to say I like the 433mhz stuff though, cheap, low power, and very reliable in my experience.

@Catsrules1 2 жыл бұрын

And most sdr have a much wider listening range. For example mine is 25MHz - 1750MHz. I am listening at 900 MHz where my power meter operates so i can pull in my power usage.

To all SDR USB Adapter user, this way you might get sent data from a remote or sensor. But the sonoff rf Bridge with tasmota is esphome you can send RF codes as well.

@0ChAnTi 2 жыл бұрын

My understanding was you can receive and send any 433 code based on mqtt connection. The limit of a specific number of rf codes is only in the tasmota web ui. But based on raw mode you can send any rf code.

Actually, is have a lot of network socket spread over the house and I use in some locations PoE adapter to just get 5v from a network socket to power wifi/ ZigBee devices. So, you might have to prepare a wifi anyway, but you can use small PoE adapter to power any 5v/12v device.

433MHz is the same frequency of tire TPMS sensors, and those sensors transmit their unique ID number. So theoretically, you could track a specific vehicle around a city.

ESPHome on the RF Bridge is a major improvement over Tasmota IMO. Especially for motion sensors. It is at least 1-2s faster.

@0ChAnTi 2 жыл бұрын

I guess this is because tasmota updates sensor data only every 5 min , and does not consider those information time critical. But you can change the update frequency to make tasmota react similar fast du ESPhome I think.

In raw mode it could listen but past 8 devices it was not forwarding events to the mosquito broker reliably. Could possibly have been a problem with the type of 433 devices I was testing though

Trying to count in my head.... 10 window sensors each with 2 codes. 1 mail sensor. 1 washer. 8 buttons. 20 devices shooting out 30 codes. EDIT:. I forgot about an RF remote... That's at least another 8 RF codes.

@0ChAnTi 2 жыл бұрын

I think the same. There is no such limit of 8 codes to read and send. some remotes doesn't send the rf code long enough. I found pressing longer the remote makes it more reliable for the bridge. But I am sure that is configurable.

@jmr 2 жыл бұрын

@@0ChAnTi My understanding is it gets a little more complicated if you want to send more then the standard 16 codes the device can memorize. I had an interesting idea though. I believe it's possible to add an IR led to it and you should be able to do both RF and infrared. The RF bridge with Tasmota would then be more capable then the RM pro devices.

This is outdated. Since latter 2021 it is only available the RFbridge R2 V2.2, that is almost impossible to hack and turn it useful! I just want to read and send a RF door command whenever necessary. But it doesn't recognize it, even if the 433 code isn't a rolling code! The sonoff RFbridge is just junk for me...
