I am using A6c module ....i need help in capturing an image from the camera and i need to send it to email id ......i am beginner in this field ....
You don't check for which sensor the message is send - message.getSensor() - and in both cases you set the relays both on Like Skywatch said.
So you could do something like:
if ( message.type == V_STATUS ) { // check if GW send a status change
if ( message.getSensor() == sensor 1 ) {
// handles sensor 1
}
else if ( message.getSensor() == sensor 2 ) {
// handles sensor 1
}
...
etc
}
@fsgraz Did some testing Today and my RFM range is over 80 meters node to node, with no long range antenna. That will be my next test, just waiting for a shipment from China to arrive. I did how ever notice an extreme improvement when I connected the gateway through a USB hub and then started to dig through the forum. @AWI once wrote about using an external PSU to power the long range NRF PA/LAN. I'll try that this weekend as connecting it to they USB port of my PI extended the range to 20 meters Node to Node.
@nagelc said in New Setup for Home Environment Monitoring – Using NRF24L01+, Arduino Pro Mini, and BME280:
bme280
I read somewhere that the temperature sensor on the BME280 is sort of an afterthought. I did a few experiments comparing them to the DHT11/12/22 and found them only a little better. (Take this with a grain of salt, maybe you'll want to do you're own experiments.) I did do a lot of experiments with the DHT's and they really suck. +/-2°C Which turns out to mean +/-2°C offset (component variation) and +/-2°C measurement: +/-4°C from what the temperature actually is. My experience, yours may be better.
Please post your experience with OTA. I haven't tried it on Arduino's but it's awesome on ESP8266. I hesitate with Arduino's because I had some erratic behaviour running Arduino's when pushing the memory limit.
I, too, use the MQTT data transport to Home Assistant (HA) and I find that excellent. Getting data from HA is a bit tricky, but do-able. I have a flow meter and use HA to store the last read; meaning, if there is a power failure, HA sends the last read on Arduino boot. I don't use the EEPROM because that has a spec of 100,000 writes which the meter would do in about a year, thus, necessitating a new Arduino.
I truly appreciate you sharing. Thanks!

I think the comments you make are good. I do have a question about the removing the regulator. I assume you mean the 5V to 3.3V regulator.
I connect to the 5V and I see lot of variation in moisture readings due to the variation in the output of the power supply (solar panel/stepdown). I have a calibration routine for that. The voltage can go as high as 4.2V, which I believe may be bad if I connect the power supply to 3.3V.
Of course, this is not a concern if using two 1.5V batteries. With batteries, the moisture reading would be more consistent over a day. Lot of advantages there. I just don't like changing batteries and I really hate it when they leak. I have every reason to believe that my power supply will last 10 years and I am fortunate to live in a place with consistent sunshine . Someone replicating my project will have to take this into consideration. My design easily accommodates a different power supply.
And my power supply could be used in other projects.
Resistive vs Capacitive sensor. I'm glad you report good results. This gives people options.
Water moisture: I've had good experience with "spraying" the Arduino with clear electronic coating and sealing the enclosure with liquid tape.

@TheoL Thanks. As @OldSurferDude says, it's an analog sensor I got off AliExpress Fuel level sensor. I chose a 0-190 ohm sensor, 450 mm long. I wired a 100 ohm resistor in series with the sensor and read the voltage with an analog channel. I do a little extra math to linearise the measurement.
I normally use mysensor nodes, but since this one is always on, I tried using MQTT for a change.
