Updated 2025-06-10 ! The sea water pump, labeled 3589907 and replaced by 21380890, was leaking a little so a change of seal was necessary. Numbers below refers to the explode view. Detach the generator belt from the pump pulley and the 2 hoses from the pump. Unscrew the water pump, 4 scews, from the engine block. Remove the cover, 7, from the pump. Pull out the impeller, 6. Remove the cam, 4, by unscrewing screw 18. Remove the washer, 22. Remove the lock ring 14 and washer 21. With a pliers try to remove the seal 8.

Updated 2025-02-15 ! Empty the fresh water system with compressed air !! One of the things, when You head back to land with the boat, is to empty the fresh water system. I have got several instructions/tips over the years but the best advise I got is to empty the pipework with compressed air. Some time ago I bought a handy Stanely compressor. Just below 10 Kg in weight including a 6 liter tank. Nice for smaller works

  Updated 2024-12-01 ! In my underfloor heating project, using Node-RED, I have to have one sensing thermometer per room/zone, seems to be 8 in total, so therefore it would be nice with a wireless battery sourced device with good resolution and frequent updates. During the test phase I used a Z-way device but the resolution was pretty bad. Another device mentioned is  the  Ruuvi tag  but since it's a bluetooth device the transmitting range could be better. After some googling I went for 433 MHz devices.

Updated 2024-11-14 ! The installation of a CTC heat pump(HP), EcoAir 600 , and the indoor module, Eco Zenith i360 , was not optimal from the beginning, so to monitor it closely I checked how to retrieve data.  The newer CTC HP:s are always shipped with a MODBUS TCP interface, without any additional hardware, which solved the issue. MODBUS was new to me but after some reading and checking I found that there is a NodeRed node which solves the interface dialog.

Fresh air at home is very important ! For more than 15 years ago, at a major renovation of our house, we installed an HRV or in Swedish  FTX system . Since then there have been nice updates for FTX equipment so when one of the fans was a little noicy and when the motor for the rotor died it was time to do an upgrade instead of repairing the old one. So we purchased an  CASA R7 Genius (R7). For me its important to get as much data as possible, to optimize energy consumption in our house, so despite that the the R7 have a nice app we also added a SEM interface to get the data, via MODBUS , that is available.

Updated 2024-08-15 ! Do You use a floor heating system from LK Systems ? We had a problem that in some rooms, despite that the thermostat worked, the temperature was too high. To check if it was the valve, or something else, I just took away the actuator and forced the valve to be closed. Cable ties did the work. The valve was OK so what was the problem ? Building your own floor heating controller,   PID controller ? 

In search of the optimal solution on how to interface our IVT Heat pump,   first try here , I stumbled over   a nice integration   for Home Assistant(HA). A first quick setup is shown at the right. The first obstacle was that it was HA which I knew about but never used.  So it was "back too school" and doing  a blog post  about a HA Core install.

If you are running the IVT Anywhere or the  Bosch Easy remote  app you probably also can  retrieve its data with for example NodeRed.  With the nice application  Bosch XMPP you can set up an integration with the cloud service supplied by your vendor.

In former posts   I used the temperatur sensor DS18B20, in several applications, but now it was time for the boats exhaust temperature and checking out YDTC-13 from Yacht Devices (YDTC). ( But please note that the YDTC can be used in any temperature application.) When you are boating, using the engine, it's  very important that the cooling water  always is present otherwise major damages can follow.  In "wet exhaust" systems it's easy to get the temperature which I posted here .

The gasket on our Kamado Joe was falling off after a very hot pizza cooking project. After some Googling, search link here , I found several post where people, to my surprise, used 3M™ Super 77™ Multipurpose Spray Adhesive. I'm surprised due to it's just specified to handle up to 65 °C, 150 °Fahrenheit.  It was also not available in the nearest shops so searching a bit further I found ...

I have tried to find some basics how a standard underfloor control system is regulating the heating, but haven't, so started with checking up  our own temperature control system from LK (TCS). I used Node-Red, with Raspberry Pi(RPi), sensing when the TCS applied voltage to the actuator. Since the actuator is running on 24 VAC and the input on a GPIO PIN is maximum 3,3 VDC I used a optocoupler to level shift.  Schematics below Please find another post here where I realized, using Shelly 1 and NodeRed , the regulating of the underfloor !!

The PCB is mounted just below the buttons Our Husqvarna dishwasher QB 6221 stoped working and displayed the servicecode 60. The washer stops dishing and the pump empties the washer. After some Googling I found some Guys who have had the same problem  and it indicates overheating. It also seems that many modells from both Husqvarna and Electrolux shares the same control electronics.

Replacing hinge for Jabsco toilet, 37045-1092, lid Sometimes it's easy maintenance, but the hardest thing is to find the right parts. After some Googling I found the part at Hjertmans  with the Jabsco sparepart number 29098-2000

Swap from toothbrush holder to soap dispenser We really missed soap dispensers, in both toilets, when we bought the boat and thought that a tooth brush holder, mounted at delivery, isn't mandatory. So after some investigation we found the Smedbo HK370 which solved the problem and also cover the old holes for the tooth brush holder.
