If you want to use a different protocol than MQTT it is probably easyer to ask Xose Perez the maker of Espurna to include another protocol.īesides, I think it is hard to make firmware, for a SonoffPOW, that works better than Espurna. Only people who are too lazy to learn to work with the webinterface of Espurna will ask for including SonoffPOW in ESPEasy. You do not have to compile the sourcecode of Espurna you can flash a binfile found here: which can be flashed very easy. Touching 3.3V, Rx, TX, or signal GND is the same as touching the live powerline, when it is powered on.

There are NO optocouplers between the HLW8012 and the ESP8266. So touching any component/wire around the HLW8012 or ESP8266 is life threatening. The way the HLW8012 works the chip needs to be connected direcly to the live powerline (115 or 230V) therefor the ground pin of the programming header is connected directly to the live input pin of the device. So it is nearly impossible to connect any other device/hardware unless you will use RX/TX for I2C.īut I strongly want to discourage to use the SonoffPOW for anything else than just do the power measurement because connecting any wire/device to any pin (including RX/TX) is extremely dangerous. The SonoffPOW has no other pins easy accessible than RX & TX. Domoticz can work with MQTT and communicates perfectly together with Espurna/SonoffPOW. No other protocol is supported in Espurna. You have to use MQTT as protocol with a server. The webinterface looks indeed much different than the webinterface of ESPEasy but it works very intuitive. I was willing to give Espurna a chance, installed PlatformIO, learned to work with the basic commands and flashed my SonoffPOW. I understand that many ESPEasy users would like to see support for the SonoffPOW in their favorite software, until 2 weeks ago I was one of them, until I received my SonoffPOW from china by the mail. I do not think it is wise to include support for SonoffPOW in ESPEasy. I think official Sonof support in espeasy is a good thing for both ESPEasy and Itead. I also offered to implement it myself if he sends me a bunch of Sonof pows to work with. I also mailed Jerry of Itead to see if i can help their devs on working on sonof support. Tinkerman) have posted teardown of the previous Sonoff TH10 & TH16 models with tests of sensors, actuators, and displays: More technical details availalable in their wiki: The button is tied to GPIO0 so just press it while powering the board and you are in flash mode. The programming header is labelled and goes like this: VCC, RX, TX, GND. I would personally not connect anything higher than a 10 amp device to this, if even that.įor hackers, Sonoff Pow is exciting as prebuilt and flashable ESP8266 device.

But it should be noted that none of these Sonoff devices have yet been FCC or CE certified, (though they confusingly have a "CE" marking but that in the case of these stands for 'China Export' and not Conformité Européenne). Sonoff Pow features a 16 Amp relay (max 3500W) and is suppose to be able to directly report wattage consumption. The "Sonoff Pow" is a ESP8266 based hackable WiFi power-switch with Power Consumption Measurement (which probably uses ITead own PSF-A85 module that integrate ESP8285). This info below is the info I found on this specific devices: ITead Studio have released "Sonoff Pow" as a cheap hackable WiFi Power Switch with integrated Power Consumption Measurement (Watt Power Meter / Energy Monitor).īefore I buy one, could anyone here tell me if the latest ESP Easy firmware specifically supports using the Power Consumption Measurement functionality of this Sonoff Pow for Watt Power Meter / Energy Monitor?
