• RE: best solution to monitor and log power usage

    Reporting back: There's now a way to bring sonoff devices into home assistant without having to reflash them:

    Sonoffs can work with Home Assistant without changing the Firmware! – 09:41
    — DrZzs

    Whether or not that includes power/energy data, I'm not sure, but I'll give it a try and report back if anyone is interested.

    Some Sonoff switching devices has got power metering.
    Upload ESPeasy or Tasmota firmware and connect with HA....

    I'm in the hunt for the same as what the OP wanted. Although there are good sensors and apps for tracking temp and humidity on a minute/minute basis, shockingly there's almost nothing on amazon offering that level of granularity for power consumption in a simple inexpensive plug-in device for appliance measurement. From what I've read, the Sonoff SONOFF POWR2 can apparently be hacked, though, as it is based on ESP8266. At $20 each it seems overpriced, but I guess that's what the market is willing to pay for it.

    There are plenty of modules on amazon that can report instantaneous power consumption, but there's no easy way to get or log that info outside the associated apps, which, as near as I can tell, are all hot garbage. For instance, I purchased a topgreener module (which I'll be returning for the reasons that follow), which is typical of what's available and which costs an average of only around $6 if you buy a set of four and which reports the instantaneous power consumption and the daily consumption to the cloud, but I see no easy way to break that information out of its smartphone app prison. Very frustrating!

    An alternative would be to build a mysensors power sensing module from scratch, using either a split core transformer or a hall effect sensor, and maybe/probably that's the least effort way to collect the data. 10 bit resolution on a 20amp ACS712 sense module equates to 20ma resolution, or about 2.2 watt resolution on 110vac mains, which is good enough for my purpose, which is to monitor the power consumption/efficiency of my two kitchen refrigerator/freezers and compare them. They seem to be running a lot more than I think they should, but the one thing I have learned from the topgreener is that they're not drawing anywhere near as much power when running as I thought they were. Well, that is, assuming the topgreener module is accurate, which is something that these days I don't think one can take for granted.

    @virtualmkr If you say so. I'd wadger if SPI is working on the atmega4809, and just regular arduino basics, that there's not a lot of adaptation needed. But I guess to prove it I'd have to do it, and I have other priorities at the moment.

    @virtualmkr I don't speak for mysensors, but while it may not yet be officially supported, I would imagine that it should work, other than maybe OTA updates/bootloader, provided that it's wired up correctly. I could be wrong, but I think you may just need to comment out whatever it is that's causing the compilation to abort with an error. Maybe some of the pin mappings need to change, but I wouldn't imagine it's terribly dramatic. If you have the gumption, give it a try and report back. After all, the atmega4809 has more flash and more ram. Running on lesser hardware would be potentially not feasible, but running on superior hardware shouldn't be a show-stopper if you work around the obstacles.

    Well, answering my own question, the atmega4809 seems to be the best of the most recent AVR chips--more memory, more flash, more UARTS, an RTC, and still has a sleep current of 100na in shut down mode while retaining the contents of all of its memory. And, interestingly, the cost is less on mouser than it is for the atemega328p. It's the chip used in the Arduino "Nano Every". However, it has no extra SPI's or I2C's as compared to the atmega328p. In fact, if I'm not mistaken, none of the low power AVR chips do.

    Do you really do that just for a problem on one website with one browser ? That's a bit extreme 😄

    Yup. I really did, but only because it looked like something a virus might do: force some bogus login to steel a password. Not that a mysensors password has monetary value, but an indiscriminate virus wouldn't know that.

    I nuked it from orbit. It's the only way to be sure.... 😉

    Reporting back: Rechecked just now, though, after wiping and re-installing Windows 10 fresh, and the same problem persists when using Chrome and trying to comment on lcduino. Mysterious! At least Firefox is a workaround.

    Hmmm.. Firefox seems to work. I'm running the most current version of Chrome, so I guess some problem with it. I'll wipe this computer in case it's a virus....
