  1. Does your ASHP modulate that far down, I have not found a 5kW one that will go below 1.8kW.
  2. Pay now save later, makes sense but only if they tell us how they are going to adjust the system so gas is not the producer of last resort.
  3. Are you close to a neighbouring property that might be causing radio interference? I notice that the data sheets on the U8 show a set of engineers DIP switches that can be used to test the zones maybe this could be a way of eliminating some issues although it looks and feels like an RF comms issue doesn't it. Don't attempt an internal playing with power on unless you know what you are doing though. The manual I found here: https://www.theunderfloorheatingstore.com/cdn/shop/files/UH8-RF_V2_Datasheet.pdf?v=16128903087641331176
  4. I am slowly compiling one for our build and a collection of spares.
  5. So can you not charge them one after the other either?
  6. How the mighty fall from grace. To be fair to Octopus they have not yet had the chance to respond to my query, I think I have all the evidence there is a problem, their own backend data shows that there is no missing data on the day and, judging by the colours in the 30 minutes slots, we were exporting more that nothing across the whole of daylight. I think this means there is a glitch in the software that is copying the data across. One can speculate on why that might have happened and it is likely that the scrape over from one to the other can be rerun, lets wait and see.
  7. Did that and here is what I see: A bit patchy but no missing data and not unlike previous / subsequent days. No '0' (Zero) blocks in the main part of the day. So it must be a software glitch somewhere although it consistently shows the same missing blocks every time in the App and on the Website. Looks like this is is one for a call in the morning.
  8. Very Buddhist!
  9. Are you telling me that buildhub members have expended 14 pages of advice, leadership, speculation, creativity and enjoyed a not inconsiderable quantity of schadenfreude to go nowhere!
  10. https://www.powerbee.co.uk/sentry-pir-sensor-1-2-w-powered.html or https://www.amazon.co.uk/Lighting-Sensor,4250Lumen-Floodlights,IP66-Waterproof-Forecourt(Daylight/dp/B0BTHJZWR5 or if you want to make your own as I did: https://www.amazon.co.uk/Waveshare-Micro-Motion-Continuous-Technology-Integration/dp/B0CT8JTMJM/ref=pd_day0fbt_thbs_d_sccl_2/257-1277778-3538256?psc=1
  11. That graph is what the inverter thinks has been exported and it aligns perfectly with the Octopus graph but has no missing 30 minutes segments like the Octopus one has.
  12. I was just running through our generation data this week and I noticed that the Octopus app was not showing me the same thing as the local inverter was for the 25th although the 26th and 24th are perfectly the same. Here are the two graphs for the 25th. I notice occasionally the Octopus takes time to show the readings, but I have never seen it only catch up part of a day. Anybody else seen this? I wonder how much back data our meter keeps locally? I will call Octopus on Monday to discuss or perhaps put this on the Octopus tech forum to see if anybody there has seen it if not seen here before. Here is what Octopus is showing for 25th. Here is what the inverter is telling me rounded to 2dp not three as Octopus.
  13. You can get them now with Radar which can detect humans and reject other animals. I have built one for experimental purposes that works well enough considering the sensor cost under a tener.
  14. Yes we will boost the MVHR but also restrict the rest of the house. I was going to experiment with flow temp and the flow sequence to see how it goes - so through the fan coil then on to the UFH so I can keep the UFH flow temperature within reaonable bounds or run the fan coils and UFH at different times. I did the calcs years ago, literally, some things have changed so I will do them again and see how it goes. It was never intended to be air conditioning just enough to keep the bedrooms below a bearable max and knock back the overheating days.
