mongoose-os Support of HLW8012 energy meter

Hello,

Many devices (like Shelly 1PM or SonOff Pow R2) are using the HLW8012 sensor to monitor the power consumption. Would it be possible to integrate the HLW8012 library (https://www.arduinolibraries.info/libraries/hlw8012) to Mongoose OS ?

Thanks

I had it on my todo list (because I have those exact Shelly 1PM units), but I'm afraid I won't be able to get to it in the short term. I can work on this in ~June at the earliest, although it would be pretty straight forward to add because the chip is a straight forward I2C speaker. By the way, Shelly 2.5 uses ADE7953 which would've been the first one on my list to implement a driver for.

Shelly firmwares are based on Mongoose, so it should not be too difficult to integrate it.

That would be awesome to have this power monitoring available for Shelly 1 PM ! I can't wait !

I just submitted https://github.com/mongoose-os-libs/ade7953-i2c which is for Shelly 2.5 and confirmed working on my unit:

I do not currently have access to a spare Shelly 1PM for the HLW8012 driver. I've ordered a few units to be able to write and test the driver, and as soon as they arrive I'll work on that next.

this is great, i can integrate it into https://github.com/mongoose-os-apps/shelly-homekit now

By the way, Shelly 1PM seems to be based on BL 0937, not HLW8012, but they are often referenced together so likely the same interface. I will update this issue once I have my hands on either, but could probably use some help testing that one.

i only have 1 and 2.5 myself, unfortunately

I got a "ready to be tested" shelly 1PM, so please do not hesitate to ask for help !

Could you check which chip is soldered in the Shelly 1PM ?

It is a BL 0937 ...

I’ve ported the Arduino HLW8012 power meter sensor library.

It's working fine with the Shelly 1PM. (BL0937) You can have a look here:

Great job !!

interesting, i need to take a look. anychance you can integrate it into the firmware as well? i don't even have 1PM to test.
