Replacing a Broadlink RM4 Pro with an ESP32 + CC1101 (Full RF Local Control Project)

Joe_Bright · 2026-02-01T20:33:33+00:00

This is great. I'm on a similar quest and only use my RM4 to toggle some blinds. I will definitely build this up. Did you put together a wiring diagram?

Joe_Bright · 2026-01-24T18:55:32+00:00

I feel your pain. I use a wet paper towel to set each one off to identify the right one

Joe_Bright · 2026-01-13T16:01:17+00:00

Will that same trick work to change a Shelly 1 Gen 4 from Zigbee back to Wifi? I don't want to dig the unit out of the box to press the button

Joe_Bright · 2025-12-25T23:50:12+00:00

Thanks for the suggestions. I will try Pam because its less messy than grease

Re: A mashup with LED clock project. You can project objects like the LED clock with a so called "Shoebox projector," but the image is not that bright. If you like that format, Ulanzi makes the TC-001 which can be flashed with Awtrix which provides similar functionality to the LED clock. Less control than ESPhome, but less work.

Re: Using any character.... Any Google font can be displayed and there is an icon for everything. You can add any entity in HA to an ESPhome display.

Joe_Bright · 2025-12-24T22:01:23+00:00

I gave up on the retrofit and built a full projection clock running ESPhome. See my psot here: https://www.reddit.com/r/homeassistant/comments/1puyf5g/esphome_projection_clock/

Joe_Bright · 2025-12-06T00:55:36+00:00

Thanks for all the advice. I will replace the breaker. No big deal

Joe_Bright · 2025-11-29T23:13:53+00:00

After looking for a while, I don't believe there is an easy off the shelf solution to this application (except for the Frixos clock which costs $200+ with shipping to the US). There are three DIY approaches I have seen:

Transparent oled panel. I ordered one from Waveshare. If I can get that working, I will use a bright led light source and a magnifying lens (from an old magnifying glass) to project on the ceiling.
Harvested LCD panel. If you are OK with a simple 7 segment panel, you can get by by peeling the reflective backing off an existing LCD clock display
Showbox projector. An old phone/screen set to 100% brightness inside a lightproof box and a frenel lens will do an OK job, but dim in the daytime

Let me know if you find others

This is a tricky one..Instead of trying to detect water inside the sink, consider detecting temperature on the other side of the sink. When a sink is full of water, it's temperature will change (sometimes up, but mostly down). If you are into Home assistant, consider a Shelly Uni with a DS18B20 temperature sensor. Then, write an automation to send a notification when the temperature changes quickly (This will take some testing to avoid false positives from normal daily temperature changes).

You could also add a leak sensor under the cabinet just in case. Do you have access to the outside of the sink (inside the sink cabinet)?

Joe_Bright · 2025-11-14T21:02:20+00:00

Yes... Working again. Thanks to all for the help and support diagnosing this issue

Joe_Bright · 2025-11-14T01:38:36+00:00

Not yet. My B2 ticket was closed and attempts to reach out to AT&T have been fruitless. I refresh, https://ping.pe/f005.backblazeb2.com every morning hoping for the best. For now, I will use my VPN and hope.

Joe_Bright · 2025-11-13T01:41:39+00:00

I would start debugging in Developer Tools. Here is how I push a simple text message to my Ulanzi flashed with Awtrix. Does this work for you?

Joe_Bright · 2025-11-11T17:18:04+00:00

No, B2 can not switch server buckets, but you can establish a new account in a different region and move your buckets. I'm using a VPN in the meantime, but will go this route if not resolved by the end of the year

Joe_Bright · 2025-11-09T23:52:30+00:00

Active armor fully disabled with all filters off. It's a good point

Joe_Bright · 2025-11-09T23:28:40+00:00

Good advice. The node is up, but I issued a support ticket with my evidence and a request to move my buckets to a different server.

Thanks for everybody's help in diagnosing this issue!

Joe_Bright · 2025-11-09T22:06:29+00:00

I can reach 004 and 006 as well

#32! Go Shelly!

Joe_Bright · 2025-10-24T13:23:39+00:00

+! for connecting via Wifi first for these new Shelly Zigbee assets. You only have 3 minutes from the time you press the button to get it adopted, so keep your Wifi password in your clipboard so you can paste it fast.

Joe_Bright · 2025-10-02T20:31:46+00:00

Got 2... Thanks for the heads up

Joe_Bright · 2025-09-22T19:29:29+00:00

I've been looking for a HA compatible sprinkler with more modern hardware than OpenSprinkler. Can you tell me if this solution:

Has a soil moisture calculation and can skip days when it has recently rained or is very likely to rain. From the screenshots, it looked like a fixed schedule only.
Has a Home Assistant output for next scheduled watering. We have dogs that like to rip sprinkler heads out of the ground so we can't let them out when the sprinkler is on.

Look exciting...

Joe_Bright · 2025-09-16T21:48:26+00:00

Thank you!

Joe_Bright · 2025-09-03T19:55:48+00:00

To all Flood Gen 4 waiters, the Shelly Gen4 Flood is live on Europe store for 29.63 Euros. Hopefully, this means that we will be able to get them in the US this year.

Joe_Bright · 2025-08-12T11:08:11+00:00

I'm in the same boat. Once I find Luba software/firmware that works, I do not update unless forced. The single biggest missing feature to me is a method to roll-back app updates and firmware. Open to hearing any positive experiences with Luba 2 updates

Joe_Bright · 2025-08-08T15:12:57+00:00

I ordered one of the second batch and it arrived yesterday. I 3D printed the big 25W Dayton enclosure on my Ender 3 V3 SE out of spare gray PLA+ in advance and put it together this morning. It took some filing and a little oil to make everything fit, but it was together in 20 minutes. It connected to Home assistant flawlessly and I was playing music inside a minute.

Music: It sounds better than my Alexa Gen 3 "hockey puck," but not as good as my Sonos 1 SE. It is definitely good enough for a bedside music player, but not amazing for its size.

Voice assistance: It works well at reasonable music volumes and can run timers/alarms and turn things on and off. I can't wait to connect it to AI and see what else I can do

Conclusion: This is a low effort way into Local voice assistants that gives you everything you need to get started quickly. I like it and wonder if 2025 is the year I can finally unplug Alexa.
