Declan52 Posted January 2, 2021 Share Posted January 2, 2021 At present I use a simple heating control to turn the heating on to my rads upstairs. I only use the rad section of it and not the central heating side. I have all my time programmes set so it comes on in the morning etc but my main issue is I would like the option to hit it to the boost option for an HR in the evening if I need to. At present I have to get off my fat ass and go upstairs and go into the hotpress and manually press the boost button. Now with getting lazy I would like to do this via an app on my phone. So what are my options. At present this is the controller I have https://www.amazon.co.uk/Danfoss-Randall-FP715SI-Heating-Programmer/dp/B001HB9LAG Link to comment Share on other sites More sharing options...
PeterW Posted January 2, 2021 Share Posted January 2, 2021 Shelly 1 could do it - bypass the live to the feed (unless it’s a Nv switch ..?) and can do by pressing a button or phone / app etc. Cheap and easy for about £10. You could go all the way and replace the whole of the system with a Shelly with a thermostatic head, you can programme them and they will also communicate with other MQTT devices. 2 Link to comment Share on other sites More sharing options...
Declan52 Posted January 2, 2021 Author Share Posted January 2, 2021 All the controller does is turn the pump on my manifold for my rad circuit. From memory it had 3 wires in the back. What they are I haven't a clue. Link to comment Share on other sites More sharing options...

Declan52 Posted January 2, 2021 Author Share Posted January 2, 2021 Am on a deep dive in YouTube videos but from what I have seen so far it could be a winner and not just for doing this job. Link to comment Share on other sites More sharing options...

They need a good set of eyes to see the terminals and a small screwdriver so I tend to make them up on the kitchen table with some tails on and use Wagos to connect them. Make a power fly lead using a plug and you can test and programme on the bench first as they keep their memory for ages. The main issue I found was getting it to recognize on the phone app, so use an Android tablet or laptop - also worth adding your phone hotspot as a secondary internet provider so if you lose the internet signal you can still access the unit. Monitoring is good too - I’ve got a couple (one is a 1PM with the sensor header) and it gives me the outputs of the sensors over a period of time and you can download the data too. Nice touch is the override switch - if you go for a retractive switch it means it can never be left “On” and lock out the controls from the app or the timer. 2 Link to comment Share on other sites More sharing options...
Declan52 Posted January 25, 2021 Author Share Posted January 25, 2021 So just to tidy this up my Shelly 1 arrived and I set it up. Very easy and well impressed so far. Here are a few pics of its setup and the app that controls it. I have a live and 2 neutral coming in plus a live going out and 2 earth. The live coming in gets split so a live goes to the L port to power it and another to the I for the input. The neutral goes to the N. The output then is the live return from the O. For tidiness I have them in a 2g box, a single would have been fine but had a double so used it. A blank face plate then covers it up. With the app I can then call it whatever it needs to be, lights or heating or whatever it's purpose is. By clicking on the correct option I can then set a weekly schedule to come on when ever I want. As a further option I can connect to the Shelly via the cloud and turn the rads on when I'm not using my home network. Link to comment Share on other sites More sharing options...
SteamyTea Posted January 25, 2021 Share Posted January 25, 2021 If you have programmed the Shelly to come on at a set time, and then you have a power failure, does it keep the same state i.e. on, or does if fail safe i.e off. And can it repickup any times that are set? Or are they done on your phone/cloud? Link to comment Share on other sites More sharing options...
Declan52 Posted January 25, 2021 Author Share Posted January 25, 2021 I had it wired up roughly just to test it and had to disconnect it and all the settings where still there. But not sure it's stored on the device or the app. Link to comment Share on other sites More sharing options...
PeterW Posted January 25, 2021 Share Posted January 25, 2021 It’s all on the device. I had one hanging off a 4G hotspot doing outside lights on dusk to dawn and forgot to plug the hotspot in and it kept going. Link to comment Share on other sites More sharing options...

I wonder what happens if you use a local network, with the settings on the phone, then the power goes when you are out. Not sure if that would be an unusual scenario or not.

PeterW Posted January 25, 2021 Share Posted January 25, 2021 Doesn’t matter. The only difference is that the device needs to get to a time server at some point to recalibrate the NTS event, and you need it to have internet access if you want it to talk to the cloud and have remote access. @Declan52 the Shelly Temp header is very good with 3 DS18S20 sensors attached as you can let it make decisions on the temperatures.

Declan52 Posted January 25, 2021 Author Share Posted January 25, 2021 I'm flat out looking at the rest of the range trying to figure out where I can use them. For such a small and very cheap item,£14, it's very easy to both setup and use. Link to comment Share on other sites More sharing options...
PeterW Posted January 25, 2021 Share Posted January 25, 2021 There is some fun and games with some of the dimmer ones - there is a good Facebook support group with the developers on it. The difference is that if you install the Shelly in the ceiling rose or roof space rather than behind the switch you don’t have the hassle of not having a neutral so you don’t need to use the Shelly1L which they have had issues of not working correctly. That way you can just use it’s a switch wire as normal on the SL line. Link to comment Share on other sites More sharing options...
