Ok, will order the "new" version when its back in stock.

That helps a bit.
Sad oh its 6 ports, but least thats useable.
A dip switch would be better.
Next version do 8 ports, and a dipswitch
TCA9548A is perfect, Im using it now.

I really want a "addressable" grove compatible switch.
Preferably in your nice packaging, and with 8 ports.
A small dip switch to set the address is fine.

Im using a TCA9548A with 8 ports, but its hardwired to port 0x70. :(

Not a passive Grove compatible coupler would be the perfect companion.
So then can control a large number of devices.

Software I already have. And happy to share.

I really enjoy working with your m5paper product combined with MQTT, and home assistant.
I would love to have a "plug-in" socket with the latest ESP32, that I can run my firmware (And Im happy to work togeather on that, as well as a "screw-in" version.

A AC Outlet strip, with individual controls per outlet would be wonderful as well.

A 3 Way light switch version of hardware would round it out.

I can easily do all of the above in software, just need your hardware.

I'm well on my way to having a app for esp32(Your epaper offering at the moment), that can drive a large number of i2c sensors, currently your relay modules, and i2c Thermistors as well, and planning to add more.

In addition Im planning virtual thermostats, which can watch temp sensors, and control local/remote devices, with auto updates to Home Assistant.

While Im writing this generally, it makes a great multi-zone radiant heat controller. (Im using it as a 8 zone heating system.

I've already got it talking to HomeAssistant, auto registering sensors, and sending updates, as well as controlling relays. All auto discovered. I've designed it for auto update as well over the network, and adding more configurabilility to it.

Just discovery your 10Amp relays with esp32, so plan to add support for them(By doing a mini version of the app).
And I saw your lcd driver, which could be used as a display. (Single grove port, so bigger switch would be useful.

I'd love to see a couple of things:

1. A TCA9548A based i2c switch with settable address. I already have support for multiple switches if you can set the address. This really would help on devices with less grove ports (Even 1 is good).
2. A 10 Amp Solid State Relay for 110-220VAC
