Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

After having both OTGW's running for a day and taking a look at both logs, it seems like the heat pump is passing on all the messages unmodified. I couldn't find anything that is changed from to logs or from the graphs created by otmonitor. With the information from this thread I can now see a clear...

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

Ah, that indeed was the case. I'm sorry for my stupidity, I must have skipped something in the manual.
I'll collect some logs and post them logs from both devices tomorrow :-)

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

I've added the second OTGW in between the heat pump and the actual boiler (Remeha Calenta), a weekend later then anticipated :p I can't seem to get otmonitor working on the second OTGW, it does receive messages but I'd notice the output from to OTGW seems different. The only difference is that this ...

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

Thank you very much for checking the logs (again) and considering the new feature.

I'll solder the second otgw this weekend and collect the logs from both of them (and share them).

Sure, forgot to upload them last night.
Here are the log covering the starting period of the heat pump.

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

I issued the UI command's in 'away' mode and restarted my heat pump. It started heating again after a 'relative modulation' level, but didn't stop anymore, so I issued the KI commands again, after which it did stop immediately.

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

The heat pump seems to stop at 21:55, which is the same time the room setpoint changes from 20 to 18 degrees. This is because different rooms have different setpoints, 20 is my livingroom and 18 is my bathroom (which I always like the be a little heated). At 22:00 the living room is set to low by t...

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

Thanks for checking the logs! The heat pump is active (= heating) during the better part of the logs, the blue line in the graph shows the power usage, which is unfortunately the only thing I can measure from the heat pump. This might explain why the water temp is rising so fast? The heatpump is pre...

Re: Tado <-> Inventum heatpump: Can I modify the OT signal?

When your OTGW arrives, please share a log of the incorrect behavior. I'd be interested to see it and try to determine which side is to blame. My OTGW did arrive and I have installed it today and observed the behaviour again, see graph: Screenshot 2022-11-27 at 22.11.22.png I've also attached the l...

Tado <-> Inventum heatpump: Can I modify the OT signal?

Hi there! I'm very new to this forum and to central heating stuff, so please bear with me if I say something stupid :P TL;DR: is it possible to adjust a signal received before it's sent out again? The situation I'm facing now is that since I've got a heat pump installed in between my Tado and Remeha...
