Trying to submit my data from ESPAltherma via the Emoncms History integration into heatpumpmonitor. I’m getting “Incorrect DHW status, negative defrost energy not included” from the reviewer. I’m not sure what I need to do.

Anyone have any tips for me?

I think I’ve worked out the ‘negative defrost energy’ issue. I had removed it from the Heat Power Out template with ‘, 0 ]|max’ after the round(2). I’ve undone that.

Still not sure what ‘incorrect DHW status’ means though.
