I’ve made your of your config to flash 9 Shelly 1 Pms and it works great, apart from none of them report current or voltage. It’s always 0.0.
Power works fine though.
Is your’s reporting V and A OK?
What may I be missing?
Seems like current and voltage is not possible without hardware modification due to missing wiring.
See https://github.com/arendst/Tasmota/issues/5716
Thank you for finding that. I’ll waste no more time in trying to get the readings!
Are these able to be flashed with tuya-convert in the normal way? Are they affected by the encryption issues affecting other Tuya devices? I am trying to do one now but it isnt finding the device.
Shelly devices do not run Tuya, so no, you won’t be able to use tuya-convert.
However - in case you missed it - Shelly devices are now natively supported since v0.115, so there is no need to install a different firmware. If you still want to run Tasmota/ESPHome instead then you would need to flash with a serial connection, and the Shelly 1PM conveniently exposes the required pins on the outside of its case.
Does anyone know if the Shelly 1PM in HA displays/reads the current/voltage items natively as well? I can’t seem to find anyone to confirm/deny that.
I flashed shelly1pm with sonoff tasmota.i think it works fine.
I have connected CF1 to GPIO14 and SEL to GPIO12.
What would be the correct configuration? I think mA may have started working but not voltage…
@alferboy I have since replaced my 1pm’s with 2.5’s, which have a different sensor. So I am not setup to test this, but referring to the esphome docs it appears my originally posted config above may be incorrect… Try using the config posted on the info page instead:
sensor:
- platform: hlw8012
sel_pin: 5
cf_pin: 14
cf1_pin: 13
current:
name: "HLW8012 Current"
voltage:
name: "HLW8012 Voltage"
power:
name: "HLW8012 Power"
energy:
name: "HLW8012 Energy"
update_interval: 60s
Also note at the bottom of the page there is a section about a “Permanent SEL Pin” hardware variant, which only has measurement mode available (likely power only). I suppose if you have a 1pm that has the pullup, you could find out how to remove it from the board to allow all 3 measurement modes.
That was my base to add current and voltage, but according to the pins used as in https://github.com/arendst/Tasmota/issues/5716 (GPIO12 and GPIO14). There is no pull-up a.
I’ve connected those wires but it seems maybe something’s mixed up on the voltage/current (they seem maybe “swapped”).

When voltage is belows 100v is when I turn off the relay. Yet current is always fixed, leading me to believe that they are somehow exchanged. Perhaps the sel pin needs invertion? very odd…
Reading that, my understanding is that the 1pm has some disconnected pins. It looks like Vorta came up with a hack that requires soldering 2 wires on the esp chip. That could be translated to esphome configs easily, but would still require the soldering.
Now, the “proof”:
Consider the “sent watts” as correct (they are pretty close).
Look at when I change the 4w bulb for a 2000w heater…
Takes a few seconds for the value to raise but when it does the “current” stays the same, and the “voltage” increases.
I think the “sel” pin needs inversion. I see no option for that…

I did that soldering, that’s the issue. I soldered the wires as suggested.
cf1_pin: GPIO14
sel_pin: GPIO12
And it does get current/voltage values.
Yet, they show up as you see, seemingly swapped.
Does anyone know if this fire hazard issue related to the ade7953 in the shelly 2.5 Shelly 2.5 + ESPHome: potential fire hazard + fix | Savjee.be is all present in the Shelly 1PM and if so if the same fix applies?
To my understanding they have different chips in them. Also my ESPHome flashed shelly 1PM and same with original Shelly FW seem to be running at the same temperature (~50 degrees).
Are you having heat issues with 1PM?
Awesome, like that and while I was able to find a working config here, I always start looking at https://www.esphome-devices.com/ first.
Now I have two questions, is esphome-devices not good to start over or why do these configs not end up on that website?
Is there anything better to get things rolling with esphome and a “working” config?
I am thinking about Tasmota Device Templates Repository - Templates for Tasmota which is THE go to site for getting devices up and running with Tasmota. Lots of people buy devices because the show up there with a configuration.
Thanks for the 1PM config anyhow.
Because no one takes the time to do so… I did a few and it takes some time to do so.
Here’s my config I compiled from a few sources I found here and there. What’s added:
- restart switch
- wifi signal sensor
- polynomial calibration which works for me much better than linear calibration
- total daily energy sensor
- overheat protection with notification

I’m sorry for not posting the config there, but it’s not really easy to do so and I can’t easily figure it out with time limitations on my hands.

Awesome, thanks for sharing your findings regarding calibration! I suspected linear was going to be a bit off… kinda surprised it lines up with 5th/6th order, but then I know nothing about the sensor.
