ESPHome weekly round up.

First up is probably the smallest Sendspin speaker amplifier from user RealDeco. It uses a ESP32-S3-Zero [1] and a MAX 98357A breakout board [2].

This thumbnail sized device turns any powered speaker in your house into a smart speaker capable of multi-room synchronised audio.

See reply for a video demo.

Another day, another issue with #ESPHome 2026.4.0: the LVGL keyboard widget is completely broken 😭

Fixed it by removing `grid_column_align: stretch` from containers with a grid layout. Not sure why.

Even though I really like #ESPHome, it's always a gamble to update because things tend to break. With v2026.4.0, it’s LVGL.

Sad part is that I cannot reproduce the issue on the `host` platform, which means I have to start the tedious cycle of modify-compile-upload-check-repeat, on a board that supports a max baud rate of 460800 and a firmware that's about 2MB in size... 😭

@zrail Interesting. I have a good home assistant setup, but I’m currently using nodered completely separately on the pi for this.

I’m just getting started with #esphome. I have a bunch of esp32s sitting around. The central nervous system of this thing is this 8-way relay. I control it with 8 GPIOs off the pi. Closing or opening a relay on the elegoo will cause 24VAC to go to the right place and make the right thing happen.

If I can put esphome on an esp32 and control all 8 relays from that, I can do all the scenes and automation in home assistant. That would be super, because the whole family is all familiar with home assistant.

Is it that simple? Pick 8 GPIOs on the esp32, and wire them up? Then just control everything in #homeassistant?
