Controlling Select Blinds

ESPHome
1

Hi,

I am trying to dial in the settings for Select Blinds controls (BF-301,305). I believe they use a 433.9MHz radio with the protocol described here:

Has anyone done this? I will keep trying things until something works and report back.

So far this is what I have for pairing, but the editor says “sync” must be at least value 0… when I delete the list, it says it expects a list…

switch:
  - platform: template
    name: "Better Shade Pair"
    turn_on_action:
      - remote_transmitter.transmit_rc_switch_raw:
          code: '10111011111011111000001010000011110101001'
          protocol: 
            pulse_length: 23
            sync: [216,-108,75]
            zero: [-15,15,-15]
            one: [-15,30]
            inverted: false
          repeat:
            times: 10
            wait_time: 0s

Ah now the editor tells me the list cannot be > 3. This will get in the way of things…

Hi, did you get anywhere with this? I have the same blind/controller and I captured the raw transmissions using my RFXtrx433xl and RFXmngr - example below. Would be great to get working.

I haven’t made much progress. I began to suspect my esp32 was faulty, and have yet to replace it. I also tried with an esp8266, but read somewhere that its pulse output fidelity was less that the esp32. I never could get a clean read of the remote transmission.

I opened an issue some time ago in ESPhome to get more parameters for the sync field, etc. While I wait for my new esp32 I will try to do what my issue requests and implement those features.

Hi
I did this last year: home assistant covers - YouTube

I have a custom Espurna firmware that can be controlled via MQTT.
Please let me know if you need more details.

6

Today I received an updated beta firmware for my RTXtrx433xl, having provided the the raw transmissions to Bert in Support @ RFXcom. I can confirm that I can now control all my blinds :slight_smile:

I’ve asked him if this will become an official 1045 beta.

Hi Donald,

Thanks for the info. A few questions:
A. Please confirm you have blinds from www.selectblinds.com ? We are thing of getting them.
B. Which motorized control from their website did you select?
C. Do you have any other updates from the above thread or other advice?
D. Can each blind be separately addressed? If not, what are the limitations?

Thanks!
Neil

Would love details on how to set this up too. Trying to do the same thing w/ HA and Select Blinds shades.

9

We ended up buying 13 shades from Leviosa, fyi. I have 6 of them integrated into HA via Node Red so far.

10

I gave up and hacked a remote off amazon to emulate button presses.

11

Which controller did you end up getting on Amazon? I’m trying to do the same. I origjnally planned on 3D printing a remote holder and using a Switch bot but what you are using seems cleaner. Does the BroadLink RM4 work?

12

Hi. Please tag whomever you are asking the question to?

13

I mean I literally bought this remote: Amazon.com

And wired esp io to it.

Hi @Leviosa – I see there is an updated integration for controlling shade systems that allows for both directly controlling blinds that support wifi-connection and controlling Uni- and Bi-direction blinds that connect to a 433MHz WiFi bridge. The Leviosa Zone uses that, I believe.

Motion Blinds - Home Assistant (home-assistant.io)

Can you please work with the devs for it to support your hub? That could quickly get you out of beta and reduce your go-forward specialized development costs.

Thanks,
Neil

Hi,
Iam interested in your code.
I am migrating from Domoticz to HASS. RFXcom is not regonizing the signal in HASS.

Found this old post. I am considering ding the same hack. Would you be willing to share exactly what you did?
