I had barometer BMP180 powered on 2xAA 1,5V , in usage from 1.March 2017 , Start battery power was 85% (not new batteries, before used) and now after 14 days of usage is 84 % , Im very satisfied. Using only without LEDs ,with power regulator on arduino.

updated my sketch with new values for SCT-013-00 result is now

@sundberg84

yes , but this solution needs buying of sensor which costs about 25-30 € , this what I write , take a look on it needs only resistors and wires (plus arduino and radio of course)

@gohan

Yes this is true but these requires of buying sensors for about 30€ for example AS3935 , I think that one , which I mentioned is cheap because it only needs 2x 10 kOhm and 3,3 mOhm resistors . Only problem which I had is bring that code works with mysensors.

Hi ,

I found this simple setup for lightning detection

[https://create.arduino.cc/projecthub/runtimeprojects/a-lightning-detector-for-arduino-9f679c](link url)

is there some way to implement it with mysensors to see it for example in domoticz ?

@gohan said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

is it reachable via IP or is it totally unresponsive?

I had same problem too.. When is longer not turned on, Sonoff disconnects from wifi , that ip is not in client list, in my case I only turn sonoff on throught black button on the top and than it is okay about day-two.

After electricity plugged off , it stops working / not connecting to wifi router, but on manual click it turns on and of , it is problem because I don't use haas config ? I dont know where can I place them, can you help me ? thanks

@mfalkvidd

And what about 433 mhz way like RFlink as usb gateway ? Will it drain less ?

@mfalkvidd

Thanks for reply and interest, but question is : Do I need use Solid state relay or classic relay or how can I switch light on/off ? Thanks

Hi ,

I want to help make led strip remote powered trought 3x AAA batteries , which can I turn on/off remotely without relay (it consumes lot of power). I think when it works on 5V battery(3xAA) it may be powered trought arduino , or any ideas ?

Tried LAN sketch after adding new hardware in domoticz this error occurs

2017-04-06 06:28:07.230 MQTT: Connecting to 192.168.2.209:5003
2017-04-06 06:28:07.335 Error: MQTT: disconnected, restarting (rc=2)

after that Sonoff blik twice. What may be wrong ?

Edit:

Understand now , it is added as classic mysensor LAN gateway , now working fine ! I tried to do it complicated way , but it was easy

@Efflon said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

@warmaniac the sonoff works just like any sensor except its configured as a gateway since that is what is needed for esp8266+mysensors . Mqtt or ethernet/wifi is just a matter of taste and your setup, skip mqtt if you don't have anything else using it.

I want to use standalone Sonoff (one device) than I must install broker (Mosquito) on my raspberry where is Domoticz running ? And how can I add than that device or how can this setup looks like.
