Redundancy and Resilience.

With the Pyronix Enforcer WE v10 panel, I know it comes with Wi-Fi built in as standard, but if you get the GPRS SIM module, does it replace the "built in" Wi-Fi module or is it in addition to it? I.e. can you install the GPRS module in addition to what it comes with OR would you need the v11...

I have a problem with one of my new Hive Heating thermostatic radiator valves that I got last month, it has stopped responding to manual temperature changes via the valve it's self, but the valve still wakes up when you go to manually adjust it as shown in the video. Have I accidentally enabled...

To have the two or more Hive TRV's in the same room function as if they are one virtual TRV. i.e. If I increase/decrease the temperature on one radiator, the other radiators in the same room will sync/update to the same temperature.

But I often hear about things being or not being up to "code", and was wondering what "code" entails and if it specifies certain tests. Do test meters like my Megger MFT1730 have much use in the states?

Hi all, for a long time I have just had three Hive TRV's. One in my bedroom, one in my bathroom and one in the spare bedroom. I have just installed 6 more Hive TRV's for the remaining radiators in the house (except the main bathroom rad what intentionally does not have a TRV) and wanted to know...

I am in the UK where when new circuits are commissioned, a number of tests are done to ensure the safety of the circuit. Such tests consist of (but not limited to) insulation resistance tests, loop impedance tests, RCD/ELCB characteristics tests, etc... How does that compare to the sort of...

Be warned, see below. (Originally filmed for 3rd party who sold me the device!) Regards: Elliott.

I know, I took common sense and intuition for granted, and paid the price as a result. As someone who is technical both in a professional sense and as a hobbyist, I saw the job as a simple one from my own perspective stupidly and did not foresee how it could be done otherwise. If you took it...

So my Granddad (who is in hid mid 80's) has had a UPS on his router for a number of years as he lives in a rural area and gets lots of power cuts and power dips. The UPS was 10-11 years old and had started to become unreliable, so I ordered him a new one. In the mean time I sent him this via...

We had our Electrolux combi microwave/fan oven replaced with a brand new one under warranty as our old one was written of due to severe rust, what prevented a previous repair man being unable to get to and replace the heater element what was leaking current to earth and tripping the RCD. I was...

I use mine to for charging my electric tooth brush and have done since about 2006. Op, has it always hummed when nothing is plugged into it or is it a recent problem?

Surprised no one's mentioned heat pumps/split type air conditioning with a heating mode.

So they can view who's at the door on their iPad's and interact with the person at the door. Essentially gain the benefits of a smart internet enabled doorbell.

I recently installed a Google Nest doorbell along with a Surf 2 Note Door Chime and a 12V doorbell transformer from TLC, and noticed the Surf 2 Note Door Chime is very quite when rung. Yes, it is wired correctly and has the module installed inside the door bell that came with the Google Nest...

I think that is a different unrelated company. This is the one that I was on about: https://www.linkedin.com/company/uk-automation-retail-ltd/about/ and use to sell consumer smart home devices like Z-Wave and X10 modules.

I assume uk-automation has closed for business as it has had a "Down for Maintenance" message on the site for a while now. Just wondering if anyone on here knows anything more about what happed to the business? Regards: Elliott.

I am well aware of that, I have a GS38 compliant voltage tester for that. I am also aware I can trigger it by rubbing it on my clothes by creating static electricity. I was just a bit surprised that it was detecting when it was so far away from any sources of electricity and was standing still...

Is my Di-Log PL107N Voltage Indicator over sensitive or are all similar non contact voltage indicators/detectors what rely on the principle of capacitive coupling going to detect unwanted sources and give false positives like featured in the video? Regards: Elliott.
