#2Good write up Sam!
Re: RF hacking my cloud-controlled ceiling fan
#3Love these write-ups, i have various 433mhz things around the home that i’ve integrated with home assistant. Probably the most useful is still a bbq thermometer with multiple probes.
Anyway i was going to post my favourite tool in this space https://github.com/jopohl/urh universal radio hacker just makes the process trivial, but i see the repo is marked archived now. Either way, the software is excellent.

#4I do not have a home so perhaps I do not fully understand. If it is warm when I go to bed, I turn on the ceiling fan by rotating the knob next to the bed. When I wake up, I turn it off. What kind of automation are you looking for?
Re: RF hacking my cloud-controlled ceiling fan
#5Funnily enough, I did almost exactly that last week, but I kind of gave up for now as my 433 MHz transceiver does not seem to work well with esphome? It does seem to output signals when I use the remote. Oh well, I will revisit when I have more time.
A major difference is that I relied on a flipper zero I had to do the 433 MHz capture instead of an RTL-SDR (I have one too, but have not needed it yet).
For reference, the transceiver is the one that came with this product: https://www.athom.tech/blank-1/8ch-inching-self-lock-relay-f... (which I already use for controlling a heater). Weirdly, it is not listed in the official esphome config (possibly because RF is a recent addition to esphome). My next step is to test it on another esp board & compare timings with what esphome generates.
I should start doing write-ups too. I came across quite a few interesting sources during this mini project (2-3 hours max).

Not OP, but I can imagine piloting it with a temperature sensor: too warm=>increase speed. It could avoid some sweat-covered wake-ups, depending on the circumstances (trade it for a noise-triggered wake-up, perhaps).
Another use-case I have for this is in a house where the mezzanine gets much warmer than below when heating during winter: detect this with a couple of temperature sensors and turn the fan on when needed.

#7I'm working on there exact path since a few months to make this process feel magical to people who can run Home Assistant, but rf capture and replay is too technical. I'm using evilcrow-rf for it and goal is to provide trivial setup flow so that copying rf remotes feels easier than signing up with the company you bought your device from. Hopefully I'll be able to do a show hn in near future.

I forgot to mention I used URH, it’s such a good tool. Very approachable for something so specialized.

For the fan - I like having it turn on in the late afternoon to freshen up the air in the bedroom.
I also really like automatically adjusting the brightness/color temperature of all our lights during the day.
It’s by no means necessary, but I don’t want to go back now.

I’m really interested in the Flipper Zero, for your use was it capturing specific encoding or raw data?
