Nice work. Agree, this is an excellent integration. I’m still running on my system without any issues 
@glyn.hudson do you know whether there is a current power sensor that gives current power consumption? I see there are cumulative power sensors but I cannot see a working current one.
Yes sensor.heat_pump_electrical_power. But it’s not very accurate, it underreports by about 20%.
The Grant heat output figure is even worse, it over reports heat by about 40%.
Therefore, the Grant COP figure should be ignored, it is totally meaningless. Grant reports a SCOP of 8 for my system, when it’s actually 4.7 according to independent MID approved meters.
Thanks Glyn.
That sensor does not seem to produce anything for me. The heat pump ran last night to heat the water & to warm the house for when I get up but that sensor stayed at zero (well according to the sensor graph in home assistant).
Interesting, it works for me.
I did notice that the COP display seems to have been removed from newer firmware versions. Maybe the power readings also been removed. I don’t think it’s no big loss, they have realised how useless the onboard energy monitoring sensor are! Incorrect data is worse than no data.
Agree
Does anyone have timeout issues with the Home Assistant integration? I seem to get random timeouts very few hours for about a minute or 2 then data is available again.
It seems to work fine for me
Dropout - Found the culprit a very poor WiFi signal. Now sorted with a powerline adapter.
I’ve about two to three hours of a thermal lag. I was thinking weather comp based on weather forecast data might be a better way to run the system. Can you shift the curve via econext?
Yes, econext can shift the curve
Top job!
I don’t have a Grant unit…but folks releasing kind of de-clouded control would certainly make me consider one / consider recommending one. 
I’ve had a strange issue recently where the Circuit 1 data and controls are unavailable in HA. The heat pump itself is running fine, circuit 1 is active.
Data and controls for the main heat source and DHW are still working fine
Any ideas? As far as I can tell the econext server is running correctly, it’s reporting
{"name":"ecoNEXT Gateway","version":"0.1.0","status":"running"}
I’m running EcoNext HA integration Version 0.1.1
I’ve attached the output of http://<IP>:8000/api/parameters

Slightly different to yours, but I had an occurrence a short while ago where all the data in HA became unavailable. The gateway was functioning but not getting any parameters. I ended up doing a reboot of the controller & that corrected the issue.
Ah do you mean the heatpump controller? I’ve tried rebooting the econext server and this makes no difference.
Yes the heat pump controller.
Restarting the HP controller hasn’t fixed the issue 
Did you also power cycle the outdoor unit?
thanks for the detailed report, I managed to figure out what the issue is. My logic detecting active circuits is flawed. Just need to test the fix before releasing an update.
@glyn.hudson in case you haven’t seen it, I released a hotfix v0.1.2 for the HA integration that should fix the problem
Yes! That’s fixed it. Nice work 
Thanks a lot.
