Hello,
I'm doing the Ethernet getway, but I have a problem.
I would like adding a a button to sync the sensor.
Someone know how I do this?And of course add button in sensor to sync the devices.
Thx
@OldSurferDude I use this. https://www.homedepot.com/p/Orbit-Solenoid-for-Battery-Operated-Timer-57861/203151515
Instead of having to hold the valve open, i can just pulse it. I use a simple motor controller to pulse it and when i need to close it, pulse it in "reverse". That way I could use a battery and if it only opens once or twice a day it's only a half a second or so of draw off the battery.
Quick Range Check on the WIO-E5-LE. The LE version uses only the low power PA, +14dBm max. Using the default settings except for 915MHz
#define MY_SX126x_FREQUENCY (SX126x_915MHZ)
#define MY_SX126x_LORA_SF LORA_SF7
#define MY_SX126x_LORA_BW LORA_BW_125
#define MY_SX126x_LORA_CR LORA_CR_4_5
I get about 190 meter range, just walking around the neighborhood, line of site except for some trees and power lines.
No tuning on the antenna. Just using a 77.9mm wire.
Not as dramatic as some have achieved with LoRa radio's, but plenty good enough for my house and yard : )
@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!
