Another I have had these running posts.

I have had 3 Sonoff relays running on 240v 50Hz for 2-3 months straight.

2 of them in IP67 outdoor lights with Phillips LED Lamps, switch on and off several times per day, Not a single hardware issue.

best $6 ever

seems to be fixed after I deleted and reinstalled the DHT library several time.

Thanks mfalkvidd

Does anyone know how I can request the current state of the relay via MQTT.

Eg HASS has rebooted, forgotten what state the switch was previously in, then it wont work untill power is cycled to the sonoff.

I want to send an MQTT message to the sonoff to get its current state. Tried looking over the forums and page and cant seem to see anything about requesting a state from a binary switch / relay actuator

What @mfalkvidd said, I had the same issue on an esp8266

Thought it might be a little harder than my pay grade.

might implement it a little later

Having an issue trying to figure how to get instant response from the binary inputs (reed switch) whilst also having a DHT in the mix.

The issue is that the binary change only gets sent when the temp or humidity is sent.

Running the code with out the DHT in there work flawlessly. and state changes are sent immediately

I assume is has to do with the Wait function in the loop, but with out that wait you poll the DHT too much and it wont read any data.

Set up is NodeMCU as MQTT gateway. running 2.0

Thanks

This sketch is awesome, First MySensors sketch I have used that worked straight off the bat.

The details page does need a few extra bits of info....

3.3v FTDI tool needed

Hold down the button on the Sonoff when you power it up to enter flash mode.

Hey Guys,

After searching a ton and doing a heap of reading, I couldn't find a multiple door switch sketch that works on 2.xx at all.

I have this sketch working on the bench on a nodeMCU, Works best when 10k external pull ups are used as well.

Going to add a relay to the sketch as well next now I have the 3 door switch's working.

So I'm just sharing this so others can see hows its done.

I'm a copy paste programmer so please dont shoot any mistakes or lack of knowledge, I'm sure there is a better way of doing it like I have seen in the relay sketch with some ++ sort of thing I have yet to work out.

This is designed to be used with Home Assistant, It will monitor a garage door with open and closed reed switches, The internal door into the house, and the relay will trigger the garage internal light. But you could use it with whatever you want.
Enjoy.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 *
 * DESCRIPTION
 * The ESP8266 MQTT gateway sends radio network (or locally attached sensors) data to your MQTT broker.
 * The node also listens to MY_MQTT_TOPIC_PREFIX and sends out those messages to the radio network
 *
 * LED purposes:
 * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/esp8266_gateway for wiring instructions.
 * nRF24L01+  ESP8266
 * VCC        VCC
 * CE         GPIO4
 * CSN/CS     GPIO15
 * SCK        GPIO14
 * MISO       GPIO12
 * MOSI       GPIO13
 *
 * Not all ESP8266 modules have all pins available on their external interface.
 * This code has been tested on an ESP-12 module.
 * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
 * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
 * - Connect GPIO15 via 10K pulldown resistor to GND
 * - Connect CH_PD via 10K resistor to VCC
 * - Connect GPIO2 via 10K resistor to VCC
 * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
 *
  * Inclusion mode button:
 * - Connect GPIO5 via switch to GND ('inclusion switch')
 *
 * Hardware SHA204 signing is currently not supported!
 *
 * Make sure to fill in your ssid and WiFi password below for ssid & pass.

@alowhum They seem to be not quite as easy for copy paste programming. I have had to do a heap of reading and learning to get it all down.

Any the other one is you search the forums for soloutions before posting and half the solutions are pre 2.x and dont work either, I don't like noob posting basic stuff due to my lack of programming skill, but people here seem quite nice and willing to help

Wait for my debouncing post later tonight if I cant work it out hahaha

This seems to be a common issue, maybe a change to highlight that the exact listed DHT library mentioned needs to be installed and no other lol

I suppose I could remove the sleep / wait function all together seems as it's going to run off mains and not a battery, which is what I would assume people wanted a sleep function for altogether.
