I think I looked at it last week but it has a fee associated with its use?

Re: Home temperature monitoring

Paul - I can't comment on EasyIOT, but I've been using Node-Red (pre-installed on Stretch) and can't praise it enough - it's really easy to install and use. There's also a large community of users that have been a huge help to me https://groups.google.com/forum/#!forum/node-red I've only been using ...

Homebrew Solution for Monitoring Heating Oil Levels

Hi All, My home central heating system runs on oil, rather than Gas. I have a 1000 litre tank in the garden, which is filled on average every 3 months. However, I need to check the oil levels manually to ensure that when it runs low, I order from the oil supplier in good time. There have been occasi...

Re: Home temperature monitoring

@paul - following this thread with great interest. With the help of the kind and knowledgeable people on this forum, I'm now controlling my hot water and central heating using a Raspberry Pi 3 and Node-Red. Still pretty basic On/Off and Daily Schedules. I'm still controlling the central heating temp...

Re: DIY Open Source PiHome Smart Heating Control

@hunty1980 how you are controlling your gas boiler (heat source)? pihome project works with mysensors library. I have a Raspberry Pi 3 connected to a relay, which is controlling my boiler - on and off. I then have a Raspberry Pi Zero W, with temp sensor (DS18B20) sending the temperature to the Rasp...

Re: DIY Open Source PiHome Smart Heating Control

This looks like an interesting project and keen to give it a try. However, my hardware setup is slightly different and wondering if this will work with what I'm running? I have a Raspberry Pi 3 connected to two relays - 1 relay controlling the Heating and the other relay controlling the Hot Water. I...

Re: Beginner - Automation of Outside Christmas Lights

By way of an update (for anyone that cares :lol: ) I purchased a cheap DS18B20 temperature senor and wired that to a spare Raspberry Pi Zero. The DS18B20 is successfully logging the temperature every 30 seconds to my Node-Red Central Server (Raspi 3) and I'm able to graph historic temp; display curr...

Re: Beginner - Automation of Outside Christmas Lights

Fundamentally, as I think you've already realised, you can't really move forward without measuring temperatures around the house. So you need to assess what's possible there, and that depends on the layout of your house and its construction. One option is to use wireless temperature sensors; must b...

Great - thank you!! Will fine sometime this week to wire in the relays and report back ;) In the meantime I'll continue putting together the logic, using Node-Red, to turn on/off and basic scheduling.

Ignore this - managed to work it out. Changed the GPIO to another input pi and changed the option in Node-Red to 'Resistor?' drop down to Pull Up...see the screenshot below.

Smart Burglar Alarm using existing Wired PIR Alarm Sensors

Hi, I'm starting to work on a home automation project where I'll use my existing home burglar system to send an email/sms if it's triggered. I've disconnected one of the PIR Sensors and connected it to the GPIO Pins on my Raspberry Pi. Here's the current setup:- Alarm Yellow Wire -> GPIO Ground (PIN...

Re: Beginner - Automation of Outside Christmas Lights

Sorry Steve - the 3 hours in the cold garage has frozen my brain - I'm not 100% sure I understand what I need to do here. I've tried to sketch what I currently have in place (I've left off neutral and ground wires for ease). Can you point me in the right direction on the diagram. The squares with 2...

Re: Beginner - Automation of Outside Christmas Lights

It was mainly the frost stat wires that weren't long enough - luckily I had some 3C+E wire in the garage, so just rewired a longer piece. With regards the earth wires - I did as you suggested - created a 'daisy chain' with a couple of spare terminal blocks, which seemed to work well. It also gave me...

Re: Beginner - Automation of Outside Christmas Lights

The wire in the top leftt is actually the frost stat, so that means the Hall thermostat is feed up via the conduit!? That actually makes more sense, since the hall is presumably a short distance away? So there should be several wires going up that conduit: 1. A T&E (twin and earth) taking power to ...

Re: Beginner - Automation of Outside Christmas Lights

...although the wire from the boiler is only 3 core. In some ways that simplifies things Now something that has thrown me there is another wire coming from the conduit that is 3 core. It seems to connect a red wire to the radiator valve. Any ideas what could this be for? How about the frost stat, w...

Re: Beginner - Automation of Outside Christmas Lights

Looking at the junction box, I would say that: 1. The wire coming in top left hand corner at the back is the thermostat 2. The wires coming in through the top conduit are probably the programmer 3. The grey wire bottom right is the incoming mains 4. The two black wires out of the bottom are the val...

Re: Beginner - Automation of Outside Christmas Lights

If you trace the wiring, this could be the best place to link in your Pi. Depending on how the system is plumbed, it could well be that you've actually got a standard Honeywell S-Plan or Y-Plan or something (these diagrams pretty much apply whoever's system it is). Do you have a single 3-pipe valve...

Re: Beginner - Automation of Outside Christmas Lights

That's a very good place to start; I assume its the output of your programmer. I also assume that you have a hot water tank. You need two mains relays controlled by the Pi (normal caveats with mains wiring apply). The first simply connects between live and terminal 3. When closed, it indicates a de...
