I could override this manually and force it to go, as I seriously doubt the esp8266 inside is wired differently, and I do have the ability to hot-air it off and manually flash it back to something usable, but I thought I'd ask about it prior to attempting that!

[Numbski]

As it turns out, it's a good thing I didn't! I was completely wrong - the GPIOs are used differently between the plug and the plug US.

Shelly Plug US (shelly-plug-u1)

GPIO #	Component
GPIO00	Led1
GPIO01	None
GPIO02	Led2i
GPIO03	None
GPIO04	Relay1
GPIO05	BL0937 CF
GPIO09	None
GPIO10	None
GPIO12	HLWBL SELi
GPIO13	Button1
GPIO14	HLWBL CF1
GPIO15	LedLink
GPIO16	None
FLAG	None

Shelly Plug (shelly-plug-2)

GPIO #	Component
GPIO00	None
GPIO01	None
GPIO02	None
GPIO03	None
GPIO04	Relay 1
GPIO05	HLW8012 CF
GPIO09	None
GPIO10	None
GPIO12	Button_i 1
GPIO13	Led 1
GPIO14	Led 2
GPIO15	None
GPIO16	Led 3
GPIO17	None

Looks like some GPIO wrangling needs to be done.

[timoschilling]

The reason why it doesn't flash is that the US plug has a different name then the (EU) plug2, shelly-plug-u1 vs shelly-plug2. During the update the name of the current and the new firmware is compared and the flash will be aboard if not match.

I think you mixed some things: There are 3 Shelly plugs out there

1. Shelly Plug
2. Shelly Plug 2
3. Shelly Plug US

The pinout you listed as "Shelly Plug (shelly-plug-2)" is that one of the "Shelly Plug", but the "Shelly Plug US" is more like the "Shelly Plug2".

I can give you a test build for the Plug US, but I have no test hardware at hand so I need to trust the Tasmota template, so it can happen that it brick your device.

[Numbski]

I have 4 sitting here and the ability to pop it open and manually re-flash, so let’s do it. :) Also, I did paste froM the tasmota template for us, but I was initially confused.

[rojer]

@Numbski ok, try this one - http://rojer.me/files/shelly/shplgu1.zip
built from the commit above, i think it might work.
if it does, please report if power consumption figures look ok (a good way to test is pluggin a heater, or a a fan, or iron and comparing power consumption numbers).
also, let me know if system temperature in web ui looks reasonable (should be 45-60C or thereabouts).
also please test reverting back to stock.

[Numbski]

Thank you for that. My mother-in-law is critically ill, and we had to leave on a moments’ notice to get to her, and my return timeline is unknown. I will get to this when I can. I am so sorry for you to go to that effort then make you wait. I may be able to do it remotely, but that may not be feasible. Tony Shadwick

[rojer]

@Numbski oh, sorry to hear that! don't worry, there's absolutely no rush with this.

I was able to try the OTA update with this build, but it doesn't take for me.

[timoschilling]

@Numbski any updates with your testing?

[Numbski]

Not yet. I am back in town though, will try tomorrow. Tony Shadwick

[just-inlewis]

I'd be willing to test a new firmware on my plug if needed. It appears the previous iteration didn't work?

[just-inlewis]

I tried compiling @rojer 's commit after rebasing master but the firmware doesn't apply for me either.

Has the name changed for my plug?

[evanpierre]

What is the state of Shelly Plug US support? yay or nay?

Attempted to install shelly-homekit today (after updating to latest stock firmware) and I get stuck with this message: "Trying to update from http://shelly.rojer.cloud/update."

Cheers and Thanks

[Numbski]

I had a death in my family last year about the time a test build was made available, and I never got around to testing it. I have five of them here, so I really should get on that.

[RaphiePS]

@timoschilling Here are the results of GET /shelly, I think this implies a non- Plus plug, but I could be wrong.

{
   "name": null,
   "id": "shellyplugus-c049ef892e60",
   "mac": "C049EF892E60",
   "model": "SNPL-00116US",
   "gen": 2,
   "fw_id": "20221206-140846/0.12.0-gafc2404",
   "ver": "0.12.0",
   "app": "PlugUS",
   "auth_en": false,
   "auth_domain": null
}

Note that it didn't come with v0.12 firmware, that was a relatively recent upgrade suggested by the Shelly Web GUI. Do you have a suggested firmware version I should downgrade to before attempting the HomeKit flash? (And if so, where I could find these older firmware files? http://archive.shelly-tools.de doesn't seem to have files for the US Plug).

[timoschilling]

@RaphiePS There three reasons why yours must be a Plus:

1. the output you posted shows gen: 2
2. The current version of non Plus US Plug is 1.x
3. The model of the gen 1 is SHPLG-U1

Take a look in the web Ui of your Shelly in the left top corner is a logo, I expect it contains a Plus.

[Numbski]

I suppose I should get on trying this today, as all of mine are plug US. Tony Shadwick

[timoschilling]

@gedeyenite If you like to test it, you could simply do it by open this url in your browser http://a.b.c.d/ota?url=http://rojer.me/files/shelly/misc/shelly-homekit-ShellyPlugUS.zip (replace a.b.c.d with the ip of your shelly)

[timoschilling]

@Numbski @just-inlewis @evanpierre @ryanshuck was someone of you able to test that build? Reminder it's only for the "Plug US" not for the "Plus Plug US".

[just-inlewis]

Hey @timoschilling sorry for the delay! I will keep an eye on this now to speed up your debug cycle!

[timoschilling]

@just-inlewis you have a Plus Plug US and not a Plug US, this build is only for the NON Plus version.

[timoschilling]

Still nobody that can test it? @Numbski?

[RaphiePS]

@timoschilling It looks like only the Plug Plus US is available for purchase, both on the Shelly site and Amazon. If I could get my hands on the non-Plus I'd be happy to test it, but I'm having trouble finding one and I figure others are in the same boat.

[timoschilling]

@RaphiePS yes the Gen1 US Plug is out of stock.

[mrala]

@timoschilling I was able to get 2.11.2 installed on two of my Plug US (non-plus) devices. They are both now overheating consistently and the homekit server keeps stopping.

Installed version:

Version: 2.11.2
Build: 20230202-214551/2.11.2-21-gdd9215b-749-shelly-plug-us-support-dirty

Debug logs show:

38287858 shelly_main.cpp:360     == System temperature normal, resuming service
39285945 shelly_main.cpp:255     === Creating accessories
39294866 shelly_switch.cpp:244   Exporting 'Shelly Plug US': type 1, state: 0
39304051 shelly_main.cpp:351     == System temperature too high, stopping service
39308855 shelly_main.cpp:314     === Destroying accessories

The device works properly after reverting back to the stock firmware.

{
    "type":"SHPLG-U1",
    "mac":"<snip>",
    "auth":false,
    "fw":"20230913-113516/v1.14.0-gcb84623",
    "discoverable":true,
    "num_outputs":1,
    "num_meters":1
}

[mrala]

Are there any other logs I can provide that would be helpful?

[timoschilling]

Looks like temperature measuring didn't work. We need to make a build with disabling it.

[rajtotherescue]

Is there any update on firmware support for the Plus Plug US?

[waffles0042]

Is there any update on firmware support for the Plus Plug US?

humble bump.

I would also be very interested in seeing this plug supported.
