Re: Internet access problems

Thanks so much! No idea why this has worked for so long and definitely through many router and RPi reboots, but this fix worked like a charm. I am back in business!

Thanks,

Paul

I am thinging that there is a problem with the DNS or router but do not know enough to know how to resolve it. This is the content of the /etc/network/interfaces file.

Internet access problems

Hi - I have a RPi3 that has been working perfectly OK for 2+ years but I was making some changes/updates and instead of moving forward, I've moved backwards. I am sure that you have all been there! The Rpi is connected to the network on a static IP of 192.168.1.21 using wlan0 and I am remoting into ...

Re: Home temperature monitoring

Hi - my current configuration is the following: - Raspberry Pi zero Wireless running EasyIoT as a web server - Two ESP8266 Adafruit Huzzah break-outs - Various OneWire, DHT-11 and DHT-22 sensors to measure humidity & temperature The ESP8266 is programmed with the Arduino IDE and receives temperature...

Re: Home temperature monitoring

This looks good. I hadn't considered using RF to communicate. I will be looking at this. I currently have a couple of ESP8266 WiFi modules with DHT-22 temp/humidity sensors that are sending results to the RasperryPi ZeroW which is running Easy IoT. I can connect to that from other computers. The maj...

Re: Home temperature monitoring

Thanks. I finally got EasyIoT working and am evaluating it. I'll move to Node-Red if I don't make progress. I think I looked at it last week but it has a fee associated with its use?

Amazing. Good response and very clear.

It worked.

Can I ask what the -AE does in the ASKPASS command string verses the -A that was there previously?

Re: Home temperature monitoring

Btidey: What sort of sampling period do you have set up on your system and what sort of power supply is used? If batteries, what sort of battery life are you seeing?

Are there any other details of your ESP8266 sensor based system you can share?

Thanks,

Re: Home temperature monitoring

Thanks - from what I have researched, they have a 'deep sleep' mode so a Lithium AA can in theory power the ESP8266 for a couple of years if readings are being taken every 5 mins or so. Practically as long as I get to once/year battery replacement, like smoke detectors, I am happy. See this: https:/...

Thanks Dougie. I will look into the /etc/dhcpcd.conf and man dhcpcd.conf files but I am not sure what to change in there and what I comment out/delete from the Interfaces file.

Also, pardon my ignorance on this, but what is a 'head -5 /etc/network/interfaces' command?
