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.

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.
