Big night. I still have a massive cold and I've finally cracked: the heating is now on. Flow temperatures will go back down by 5 ˚C once we're a bit closer to equilibrium.
I had hoped to hold off until the smart meter goes in on Friday but the flesh is weak. #heatpump #newseason #OpenEnergyMonitor

For #Junited2025 I admit to capitulating and joining the #OpenEnergyMonitor forum, which is every bit as good as one would hope. The secret is that I actually joined it to support my current live #PhD #research experiment with the info it makes freely available, which shows the value of #open!

Je ne sais pas ce que fait #RTE ou #EDF, mais la tension a drôlement baissé entre minuit et 15h, allant jusqu'à une pointe de 184V ! Bien en dessous des 200V garantis.

L'éclairage et l'électronique commence à sérieusement avoir des soucis à cette tension !

A christmas gift for you all... #opensource #esp32 DIY energy monitor based on #esphome and #openenergymonitor libs.

It can read voltage and current of up to 3-phases and output power and electricity consumption to #homeassistant or #mqtt.

+ a full tutorial from hardware assembly to calibration and configuration.

@petereastern @brendanp My plan is eventually to link my #heatpump to me #openenergymonitor box but I don’t know where to start in terms of the Modbus connection. I’m told there’s a board one can instal… I also need to put in an independent heat meter and swap my two electricity meters. so that I have independent verification. The latter I’ve already bought and are sitting waiting for someone less likely to electrocute themselves than me to swap them over. 😂

For the #heatpump enthusiasts out there! we are developing an initiative to share open data from heat pump systems over at #OpenEnergyMonitor

Here's the forum thread https://community.openenergymonitor.org/t/public-heatpump-dashboards/20137

and a couple of example dashboards to geek out on:

5kW Mitsubushi Ecodan ASHP
https://emoncms.org/midterrace

5kW Samsung ASHP
https://emoncms.org/samsung5kw

Vaillant Arotherm 3.5kW ASHP
https://emoncms.org/Heatgeek

11kW Mitsubushi Ecodan ASHP
http://emon.cryosphere.co.uk/ashp

Public heatpump dashboards?

I was wondering if any members had made their heatpump monitoring graphs public? Is it possible to share publicly the whole built in ‘heat pump app’? I asked so that interested up and coming heat pump owners (ie me) could take a look? I’m totally curious about run times and minimum loads / COP etc at different outside temperatures. Appreciate that every install will be different and will perform differently. 👍 I’d hope to work out a way to share my Heat Pump App when I get mine installe...

@Shinra j'en n'ai pas entendu parler pour un truc "interne" aux contrôleurs.
En externe y'a toujours #OpenEnergyMonitor, mais c'est un autre délire...
