Shelly Plus 1PM Mini

Hi all,

Bought 4 of these and am having nothing but trouble with the 3 I’ve installed.

They’re closer than any other device to my access points, report -60dB or better when they’re working and have static IP reservations at the router. Not using the cloud, using the HA integration.

They can work fine for a day or two then they go offline. All three of them do it; I’ve never had any other ESP based device perform as badly. I’ve got over 30 devices now including Sonoff, Shelly 1, Shelly Dimmer 2, some unbranded wall switches and some ESPHome stuff I’ve made and they’re all flawless, even the ones that are way outside in the garage. I know my network is good - I surveyed and set it up based on Ekehau’s heat mapper specifically for my IoT stuff.

I’ve disabled roaming on them, turned off the APs and BTLE. Yesterday one of them went 22 hours without going unavailable, then flicked in and out of consciousness before dying until I cycled the power (was offline for 9 hours). When they go offline their web interface doesn’t respond, yet my Ubiquiti dashboard shows them as though they’re still online.

I picked one of them last night and flashed it with ESPHome, to rule out any problems with the Shelly firmware. With ESPHome it’s not gone unavailable once, but toggling the relay takes 3+ seconds and I’m unable to flash anything else to the ESP without a serial connection; the ESPHome integration just throws an unknown error.

Basically crap. Just wondering if anyone else has had experiences this bad?!

EDIT: They’re all in the same room. Two in the ceiling, one in the wall. I have a Shelly Dimmer 2 in the same room also, between the three and further from the AP than the closest ones. That’s flawless. Don’t get it.

Support for the Shelly Minis has only just been added. There could be issues with it. Open a new issue here:
